Beijing Airport Automated People Mover (APM) System
In cold weather climates, Automated People Mover (APM) system running surfaces, such as guideways, power and signal rails, switches, and turntables, require de-icing for safe operation.
Beijing Capital International Airport needed to keep snow and ice from forming on the guideway and associated running surfaces of a new APM system for the Beijing Capital International Airport. This APM system was part of the airport’s extensive expansion program in preparation for the 2008 Olympics being held in Beijing, China.
Pentair Thermal Management can engineer heat-tracing systems to accommodate the most unique aspects of de-icing applications, including embedded guideways and tight clearance and configuration areas as seen in rails, switches and turntables.
Bombardier Transportation, acting as the prime contractor for the Beijing Capital International Airport Authority, contracted Pentair Thermal Management to provide all engineering, design and products for an integrated heat trace system for a new APM. The system was designed and based on predicted heat requirements and thermal profiling of the guideway running surface.
Pentair Thermal Management performed a Finite Element Analysis (FEA) to predict the heat requirements and snow melting characteristics under varying conditions. A total of eleven case studies were submitted using data on Beijing’s snowfall and temperature averages over the past 100 years. This information was used to establish and implement operating philosophies for the customer that allow for the most suitable and energy efficient heating system solution.
There are specific challenges inherent to this type of project including:
- Extremely long running surfaces associated with the guideways
- Tight clearances
- Unique configurations typically associated with power rails, switch points and turntables
Pentair Thermal Management provided a final system design that incorporated various heat‐tracing technologies to address these issues.
The largest engineering challenge for the new APM at Beijing Airport lay in the design of the Skin‐effect heat tracing system for the concrete guideways. By developing and utilizing specialized component assemblies, Pentair Thermal Management was able to design a system with long continuous circuits averaging over 1000 meters in length. Other unique components and assemblies were designed specifically for this project to be compatible with the power rails, switch points and turntable layouts.
By doing a thorough analysis and design for the deicing system, Pentair Thermal Management created an overall solution that was cost effective and very reliable. The de-icing system used the best heat tracing technology and customized components and assemblies for this application.

Downhole Heating Application for Heavy/Extra Heavy Oil
One of the world's largest accumulations of natural bitumen and heavy oil is the Orinoco Heavy Oil Belt in Venezuela. It has been estimated that there are about 270 billion barrels of recoverable oil in place. These reservoirs hold a heavy to extra heavy oil with API range of 16 to 8 API with high viscosities that inhibit the mobility of the crude. The use of diluents has become standard practice to move this oil, resulting in an expensive maintenance process, not only to procure but to treat (separate). In 2008, Pentair Thermal Management supplied and installed a PetroTrace Downhole Heating System for use in the Orinoco Heavy Oil Belt to assist the oil recovery.
Pentair Thermal Management engineered a PetroTrace Mineral Insulated (MI) Downhole heating system for this deep onshore, horizontal well to deliver bottom-hole type heat to reduce the viscosity of the extra-heavy oil in this producing well.
The PetroTrace Downhole heating system supplied produced 65 kW along the 3,000 ft (914 m) of the 7-in slotted liner. The heater was designed so that more power was delivered towards the end of the liner where heat is needed the most. The heater was configured by three heating sections with a lower power density in the sections closest to the Progressive Cavity Pump (PCP). The heater was deployed inside the horizontal section of the slotted liner by attaching it to the outside of a 2-3/8 in supporting pipe.
The supplied system included a control panel for ease of operation and monitoring of temperature and current.
The products utilized for this flow assurance project include Pyrotenax Mineral Insulated (MI) heating cable for bottom-hole heat and Raychem control panels.
The heating system significantly lowered the viscosity of the oil by increasing the temperature in the liner approximately 50°F (10°C) in less than 24 hours. As a result, oil production increased 65% from 340 BOPD to 560 BOPD.
Downhole Heating System Increases Production in CA Stripper Wells
Some of the largest heavy oil reserves in the continental United States are located in California's Central Valley oilfields north of Los Angeles. The reservoirs in this area are estimated to be a 40-billion-barrel resource, primarily of heavy crude approximating 13 to 9 API located in shallow reservoirs not deeper than 2,300 ft (701 m) in depth. Pentair Thermal Management has been supplying PetroTrace Heating Systems to oil companies in this region since 2005.
Pentair Thermal Management engineered a PetroTrace Mineral Insulated (MI) Downhole Heating System for these onshore low-flow, shallow wells to deliver bottom-hole type heat to improve the mobility of oil in the near wellbore area and allow for an increase in production.
The PetroTrace Downhole heating system supplied produced 27 kW of energy in the pay zone at 600 V. The Downhole heaters were secured to a stinger pipe below the pump that contained several passes of MI cable, producing a power density of 300 W/ft.
The supplied system included a control panel for ease of operation and the monitoring of temperature and current. To allow the client to confirm target temperatures along the length of the heated section, multiple sensing thermocouples were installed to provide temperature measurement.
The products utilized for this flow assurance project include Pyrotenax Mineral Insulated (MI) Heating Cable for bottom-hole heat, and Raychem Bottom-Hole Heating (BHH) Control Panels.
Production increased from 3 BOPD to over 20 BOPD, resulting in a payback of less than four months.
Expertise in Heat Tracing Systems for Crude Oil Transfer Ensures Flow at CA Refinery
The Tesoro Refinery in Martinez, CA needed to heat trace its Amorco Wharf pump station and transfer lines to ensure crude oil flow from its off-load wharf to a series of storage tanks. Detailed engineering drawings for the heat tracing did not exist and the project proved to be complicated due to the intricate valve piping at the pump station. The client had a tight deadline and so they contacted Pentair Thermal Management.
Due of the variety of pipe sizes, high number of large and small valve assemblies and the tight temperature maintenance requirements, the heat trace design required creative solutions and flexibility to best meet the customer’s needs. Pentair Thermal Management engineers visited the refinery and completed a field design by taking pipe measurements and designing the heat tracing system on site. They worked with the local refinery personnel to define the necessary power distribution systems, power-point locations, necessary control and monitoring solutions and heat trace cable recommendations.
Our experience with crude oil transfer and marine applications allowed us to develop a timely and cost effective solution for the Tesoro Refinery. Raychem XTV self-regulating heat trace cable was specified for all of the piping in order to minimize the installation costs as well as to ensure the temperature maintenance requirements. Raychem 920 Control & Monitoring panels were combined with transformers and a power distribution system in a self-contained skid to reduce on-site installation time and expense.
The installation was completed in accordance with Tracer safety standards resulting in a 100% safety record on the project. Along with the quality installation of the heat tracing system by experienced craftsmen, Tesoro received a Warm Pipe Warranty as a guarantee of the quality of the installation. Experience, creativity and flexibility were key in completing this project for Tesoro Refinery. Put these traits and capabilities to work for you on your next job.
Fuel Leak Detection for Crude Oil Storage Tanks at French Refinery
A refinery in France sought a system capable of quickly detecting hidden leaks beneath its four crude oil tanks. Undetected leaks beneath oil storage tanks pose a major threat to operational safety at oil storage facilities and have the potential for disaster.
The refinery needed a specialist sensing cable to quickly detect the presence of liquid hydrocarbon fuels at any point along its length, without reacting to the presence of water.
Pentair Thermal Management installed its TraceTek TT5000 Oil and Fuel Sensing Cable at the refinery. Each of the four crude oil storage tanks at the Notre Dame de Gravenchon refinery now has TraceTek TT5000 cable buried beneath its perimeter. The cables are attached to the TraceTek Sensor Interface Module to continuously detect and pinpoint any oil leak.
Pentair Thermal Management’ TraceTek system is constantly ready to alert the operators to any fuel leakage. This allows the refinery to detect leaks early, giving the response team enough time to react before the situation becomes critical. The system protects the operational safety at the oil storage facility and shields from potential disaster.
Leak-Sensing Cable Helps Protect the Cabinet War Rooms Museum, London
The Cabinet War Rooms are situated in the basement of the Treasury building in the Parliament Square in London, where Winston Churchill directed the war effort. It is now a museum containing irreplaceable artifacts and exhibits from that time. As part of the recent refurbishment of the Treasury, facilities management noticed undetected water leak could damage or destroy many of the historic contents.
Pentair Thermal Management advised that the Cabinet War Rooms required a system that is capable of quickly detecting, locating and alerting the facilities manager to water ingress.
Pentair Thermal Management installed a TraceTek leak detection system with over 2.3 kilometers of TraceTek TT1000 sensing cable to detect water along with Sensor Interface Modules and Master Modules, each of which can monitor up to 500 feet (150 meters) of sensing cable. The modules are connected to a building management system via a RS-485 network. When water is detected, the TraceTek Sensor Interface Modules provide an alarm and leak location display.
Pentair Thermal Management’ TraceTek monitoring system allows the museum to quickly take remedial action to protect the exhibits. The leak detection network has been designed to be versatile enough to enable the system to be extended to other areas in planned phased expansions.
Optimized Heat Management System Ensures Safe Sulfur Transport at Large LNG Plant
Qatargas Sulfur Transfer Line’s heat management system challenges included:
- A tight range of allowable temperature from 125°C to 145°C for molten sulfur, with a set point of 135°C along the entire length of pipeline.
- A large outdoor pipeline with significant weight, multiple flow paths, and vertical expansion loops at every 150m.
The customer also required the capability to re-melt and re-heat solidified sulfur without causing overheating or over-expansion. Additionally they needed a redundant heating system that would cover 100 percent of the pipeline.
Pentair Thermal Management’ ability to engineer and integrate multiple technologies with its expertise in construction and commissioning heat management systems resulted in a world-class, safe, reliable and efficient electrically traced sulfur pipeline.
To meet the needs of this application, Pentair Thermal Management employed a heat management system that included the following:
- An inherently safe Raychem Skin-effect Tracing System, which has high exposure temperatures and efficient heat transfer to the pipe
- A state-of the-art Raychem control and monitoring system with vacuum contactors.
- Finite element analysis to determine the temperature profile of sulfur across the cross-section of the pipe.
- Fiber-optic based distributed temperature sensing system that provides a dynamic pipeline temperature profile at each meter within 1°C accuracy for the entire length.
- A multi-power heat delivery mechanism with 7 percent of installed power for normal operating conditions and 100 percent of installed power for heat-up/re-melt conditions.
- A multi-later thermal insulation system with high temperature expanded inner layer, load bearing closed call foam out layer and UV resistant jacket.
- Full service procurement of materials, project management, construction and commissioning of the pipeline.
A Pentair Thermal Management Heat Management System provided Qatargas Sulfur Transfer Line with the following benefits:
- The Raychem STS Skin-effect Tracing System minimized the number of circuits and also resulted in better heat transfer and a low temperature differential between the pipe and cable sheath, thus leading to a safer design.
- The finite element analysis and Raychem control and monitoring solution ensured that the sulfur temperatures did not go outside the tight control temperature range under normal operating conditions.
- The fiber-optic distributed temperature sensing system provided continuous monitoring of the temperature along the entire length of the pipe. This helped to locate hotspots along the length of pipe during the re-melting process and in turn avoided excessive pressure generated by melting sulfur.
- Multi-power heat delivery mechanism and multi-layer insulation systems not only optimized the total operating costs of the system but also contributed to a shorter re-melt duration.
- By assuming total responsibility of the heat management system, Pentair Thermal Management ensured that the project was completed on time, and to the satisfaction of the customer.
Optimized Heat Management System Reduces Costs at Ethanol Production Facility
Bridgeport Ethanol is a green-field 40-million gallons/year ethanol production facility in Nebraska. Their heat-tracing application needed to be modified to include pipe freeze protection for water lines, tank heating and process temperature maintenance of syrup, silage and caustic lines. They brought in Pentair Thermal Management’ Tracer Turnkey Solutions team in May 2008 for the project.
The Tracer Turnkey Solutions team completely engineered, procured and installed the necessary heat management systems (HMS) at Bridgeport Ethanol. The team leveraged a complex and diverse range of Raychem control and monitoring solutions to reduce the number of necessary circuits to 35. And in doing so, the team was able to reduce the total cost of the heat management system at Bridgeport Ethanol.
Products used included the Raychem 200NG with proportional ambient sensing control (PASC) for the pipe freeze protection and broad temperature maintenance applications. In PASC, the power to the heat tracing is proportioned based upon on the ambient temperature.
The Tracer Turnkey Solutions team also selected a combination of the Raychem 920 and HTPG local control system to control and monitor remote circuits for tank heating as well as pipe freeze protection of the water lines. These areas were respectively 800 feet and 450 feet away from the centralized control panels and would have required 2/0 power wires due to the voltage drop.
Additionally, the team chose the Raychem 200NI with line sensing control for the critical temperature maintenance applications. To reduce the RTD wiring costs, we used the Raychem power line interface technology (PLI) and Smart End Seals (SES) to transmit temperature and continuity data over the heating cable conductors.
The project was successfully completed in November 2008. With the use of PASC algorithm, the Tracer Turnkey Solutions team was able to reduce Bridgeport Ethanol’s operating costs by 75 percent from that of the standard ambient sensing controller. The conduit and wiring costs were also greatly reduced by using a local control system, and the use of Raychem power line interface (PLI) technology eliminated the estimated $40,000 of RTD wiring costs.
Pentair Thermal Management Installs Electric Heating Solution for Offshore Flow Assurance Application at Maari Field
In March 2006, Pentair Thermal Management was brought in to install an electric heat-tracing system into an offshore oil production facility located in the Maari Field off the coast of New Zealand. The customer was having trouble with wax buildup in the production tubes of five separate wells, which was interfering with oil flow from the reservoir to the platform.
The Pentair team faced tight installation constraints between production tube and casing, thereby necessitating a unique solution of system deployment through the production tube. Minimizing the platform footprint relative to the power supply and associated system controls was also a challenge the team faced.
For similar wax mitigation applications, Pentair Thermal Management normally employs heaters externally strapped onto the production tube, such as the PetroTrace DHSX™ or PetroTrace MI product lines. However, the project-specific restrictions and constraints at Maari Field made those technology applications difficult to use. To overcome this, the Pentair team developed a unique solution utilizing the STS technology, resulting in the first-ever application of Skin-effect Tracing System to downhole heating. The team combined the systems to a common power and control scheme, thereby minimizing the need for several large pieces of topside equipment.
The PetroTrace STSi Skin-effect Tracing Systems at Maari Field utilized an STS™ wire that was inserted into coiled tubing filled with dielectric fluid. It was then installed inside of an offshore production tube to deliver heat along the length of the entire production wellbore maintaining the flow rates necessary to prevent wax buildup.
The PetroTrace STSi heaters installed on the wells provide power outputs up to 150 W/m for a total of up to 315 kW per well. To maximize heat transfer, the team installed the heaters within the production tube. The successful development of this field was largely due to the efficient heat transfer of the STS system, preventing the crude from reaching the wax formation temperature even with only a 3°C variation between the reservoir and wax appearance temperatures.
The new PetroTrace STSi Skin-effect Tracing Systems at Maari Field were successfully completed in July 2009. The project-specific solution proved to be reliable and provide realistic returns on investment as it mitigated wax buildup in the well’s production tube and maintained consistent oil flow from reservoir to topside.
Pentair Thermal Management Installs Electric Heat-Tracing System at Tesoro Golden Eagle Refinery
The Tesoro Refinery in Martinez, Calif., needed its Amorco Wharf pump station and transfer lines heat traced to ensure crude oil flow from its off-load wharf to a series of storage tanks. Detailed engineering drawings for the heat tracing did not exist and the intricate valve piping at the pump station proved to be a challenge. The client had a tight deadline, so they contacted the Tracer Turnkey Services Team at Pentair Thermal Management.
Due of the variety of pipe sizes, high number of large and small valve assemblies and the tight maintain temperature requirements, the heat-tracing design required creative solutions and flexibility to best meet the customer’s needs. Pentair Thermal Management engineers visited the refinery and completed a field design by taking pipe measurements and designing the heat-tracing system on site. They worked with the local refinery personnel to define the necessary power distribution needs, power-point locations, necessary control and monitoring solutions and heat-tracing cable recommendations.
Pentair Thermal Management’ long history of experience with crude oil transfer and marine applications allowed the team to develop a timely and cost-effective solution for the Tesoro Refinery. The team installed 7,000 ft. of self-regulating heating cable and 40 control circuits. The Raychem XTV self-regulating cable was specified for all of the piping in order to minimize the installation costs as well as to ensure specified maintain temperatures were met.
In addition, Raychem 920 control and monitoring panels were combined with transformers and power distribution panels in a self-contained skid to reduce on-site installation time and expense.
The installation was completed in October 2007 in accordance with strict safety practices resulting in a 100 percent safety record on the project. The successful installation of the new heat-tracing system allows Tesoro Refinery to seamlessly pump crude oil from its Amorco Wharf pump station to the storage tanks. Tesoro also received Pentair Thermal Management’ Warm Pipe Warranty as a guarantee of the quality of the installation.
Pentair Thermal Management Installs Floor Heating at Syon Park Waldorf Astoria
The newly constructed Syon Park Waldorf Astoria Hotel, on the outskirts of London, called on Pentair Thermal Management to provide floor heating solutions for its 5-star, 13,000 square meter complex. The hotel is on the grounds of the Duke of Northumberland’s mansion and had been a home to the duke’s family for more than 400 years.
TTC went into the hotel to install Raychem Quicknet-160 floor heating mats to provide warmth under the luxurious marble and limestone floor covering. TTC also installed the Raychem floor heating systems in the hotel’s luxury spa.
The Raychem systems are controlled centrally via the hotel’s building management system, which switches on the floor heating when the room is occupied. Of the 151 guest bathrooms, 124 have had this technology installed.
The main spa area includes 350 square meters of T2QuickNet heating mats, which are insulated using Raychem Isolecta insulation boards to reduce heat loss and increase energy efficiency by about 20 percent.
The project was completed in October 2010 and guests were welcomed to the hotel in early 2011.
Pentair Thermal Management Installs Heating Solutions at London Rolex Building
Pentair Thermal Management was brought in to employ a variety of its heating solutions at the new Rolex Building in London, England. Rolex was looking to convert its heating to a simpler, lower cost single pipe system that required less maintenance.
Pentair Thermal Management provided hot water services using the Raychem HWAT single pipe hot water temperature maintenance system.
Pentair Thermal Management installed more than 400 meters of cable to provide hot water all the way to the point of use, 600 meters of WinterGard pipe frost protection cables, and RayClic connection devices to safeguard the chilled water supply lines from freezing.
In addition, a beautifully tiled floor at the entrance foyer now welcomes visitors with the ambient warmth of Raychem floor heating systems, with the installation of nearly 50 square meters of T2QuickNet.
The reduction of pipework left more space for the single pipe and insulation so that thicker insulation over the system could be used to increase its efficiency. The total estimated energy savings for this project will be approximately 50-60 percent. Even with the higher unit cost of electricity, the actual customer savings are expected to be 5-15 percent.
The design, supply, and installation of the Raychem systems were undertaken by Jointing Technologies, a Pentair Thermal Management distributor partner headquartered in South East England. The project was completed in October 2010.
Pentair Thermal Management Installs Tank Insulation System for Disneyland Resort
Pentair Thermal Management was hired to install its Trac-Loc tank insulation system on a thermal energy storage (TES) tank built by Chicago Bridge & Iron at Disneyland Resort in Anaheim, Calif. Vital to the park’s operations, the tank had to have advanced thermal functionality as well as an aesthetically pleasing design since it’s located by the park and private hotels.
Working in a very tight space, Pentair Thermal Management ensured park operations weren’t interrupted and that guests weren’t bothered while insulating the 58 foot tall tank with an approximate surface area of 18,500 square feet. They also paid close attention and adhered to stringent safety standards due to the close proximity of numerous guests through the project’s five week duration.
Complete with the new insulation system, the neutral-colored Disneyland TES tank blends with its surroundings and chills close to two million gallons of water during off-peak hours. The chilled water is then used during the day by surrounding Disneyland Resort buildings for the HVAC systems.
The installation of the Trac-Loc System helped ensure that the tank's service to the surrounding area is done effectively and in a more economical manner. Additionally the tank is protected from heat, resulting in an energy savings of approximately 3.3 million kWh per year.
"The Walt Disney Imagineering team really challenged us to be cognizant of the details from project award through onsite completion. This tank will be an essential part of the day to day activities of Disneyland. We're confident we met the challenges of this project with the highest safety standards, detailed scheduling, and quality assurance of the installation." - Blake Heger, Project Manager
Pentair Thermal Management Provides Single Source Heat Management System for Biodiesel Terminal in Canada

The project was managed out of the Kitchener Services office in Canada and they utilized resources and talent from service centers in Houston and Edmonton to complete the project on schedule.
The project entailed a detailed heat tracing design in combination with insulation on the B100 tank. Raychem XTV heating cable was used for its design flexibility to maintain an accurate temperature; Tracer Trac-Loc, a vertical lock-seam tank insulation system, was used to insulate the tank.
The comprehensive design was easily integrated within the customer’s timeframe and provided the accuracy required.
Pipelines Traversing Beaches on Mayotte Island, Tanzania and on the Coast of Chile
When tankers unload their cargo of crude oil or refined fuels into small oil ports and pipe systems, there’s risk to the sensitive beach and dune zones they pass through. In locations like these from Mayotte Island to Tanzania to the coast of Chile, SCADA-based leak detection systems may be ineffective since the pipes are small and the flow is inconsistent.
Environmentally sensitive areas required a more advanced product that can detect and pinpoint the location of a leak instantly.
The TraceTek TT5000 pipeline monitoring system uses specialist hydrocarbon leak detection cable that is buried inside slotted conduit and located in the same trench as the pipework. The system is installed with one kilometer circuits to monitor the entire pipeline and pinpoint leaks within one kilometer in either direction.
Each circuit on the system has its own Sensor Interface Module (SIM) and up to 128 SIMs can be networked back to the alarm and user interface panel. This system can be installed along with single wall steel pipes to provide a long-term monitoring and leak alert capability.
Raychem Pioneers Combined Temperature and Moisture Sensor
In the summer of 1986, 300m of gutter snow melting cable was installed at CKW Ruopigen (Switzerland). As well as guaranteeing roof snow melt, the client’s objective was to accurately determine the operating cost of the system.
The installation was divided in two systems, each with a different control method. One system operated with temperature sensing only; the other with temperature and moisture sensing. Temperatures and power consumption were measured during four months.
GM-2X snow melting cable
Electricity consumption dropped by 78% when the system was operated using temperature and moisture sensing, compared to temperature sensing only.
Taking Energy Expertise Underground
TO SAFETY TRANSFER CRUDE OIL OVER A RECORD-BREAKING 700km, PENTAIR ASSISTED CAIRN IN DEVELOPING THE WORLD'S LONGEST HEATED AND INSULATED PIPELINE
In 2004, Cairn India Ltd. uncovered India’s largest onshore oil discovery in 25 years. More than 4 billion barrels were discovered 1.5 Kilometers below ground in the Thar Desert. In this remote, undeveloped area, the oil needed to be transported to refineries 700 km away, without roads or rail.
In all, the transfer solution had to cross a variety of urban and rural landscapes, as well as 34 major rivers. The highly viscous composition of the oil only complicated matters, as it solidified to a hard wax as soon as it reached the ground surface. In order for the oil to flow, it had to be heated to and maintained at a temperature of 65° C (150° F).
To be as safe, reliable, and economical as possible, the best transfer option was determined to be, an underground pipeline employing a sophisticated engineering system known as the “Skin-Effect Heat Management System” (SEHMS).
Cairn tapped Pentair Thermal Management to help implement the Mangala Development Pipeline Project, leaning on the company’s technical expertise and localized presence in India. Pentair held a strong track record with similar projects, making it uniquely qualified to execute the complex engineered system.
THE HEAT MANAGEMENT SOLUTION
Pentair Thermal Management designed and engineered a custom implementation of its Raychem STS proprietary heat management system. As the backbone of the underground pipeline, it maintains the flow of the crude oil at an elevated temperature, irrespective of changes in environmental conditions.
The Mangala pipeline consists of a 24” pipeline buried 1 meter below the ground and thermally protected with three different insulation layers. The insulation minimizes heat loss, prevents corrosion, and reduces any potential physical damage to the pipeline.
AN INTEGRATED EFFORT
Pentair teams in Mumbai, India and Houston, Texas, US worked daily with the engineering teams at Cairn to design and implement the important and challenging application. The collaboration was vital to progress on a project that would take over five years to complete.
Throughout the development, Cairn took great care with regard to the regions social and environmental impact. While the shortest available route for the pipeline was sought, a direct line would have run through the Gulf of Kutch, home to a fragile marine ecosystem. Cairn engineers extended the pipeline route by 75 km in order to avoid the area, ensuring its conservation.
From an engineering standpoint, the ability to bury and submerge the pipeline while not adversely affecting the performance of the HMS enabled Cairn to minimize the chances of a potential leak or spill due to interference.
Economically, the Mangala Pipeline Development has been a major boon to India. The resulting domestic oil production reduces India’s import bill by more than $6 billion USD each year. Besides affording the country energy self-sufficiency, the crude oil has enabled India to enter the market as an exporter.
“Technology like Pentair’s “Skin-Effect” Heat Management System will be increasingly vital as the search for energy resources requires going to areas that are remote and undeveloped.”

The world's most luxurious cruise lines are equipped with Raychem's energy-efficient heat tracing technologies
Each cruise liner is built to individual specification and to tight deadlines. Depending on the design, between five and nine kilometres of heat-trace cabling need to be deployed for frost protection and temperature maintenance of oil pipes on each liner. The pipework is complex and each installation must be completed in about 15 weeks.
Pentair Thermal Management Germany is supplying EHT systems based around Raychem self-regulating and constant-wattage heating cables. BTV self-regulating cables are deployed for frost protection of pipes and instrument lines maintaining temperatures above 5°C. The major part of each installation is the deployment of FHT2-CT constant-wattage parallel circuit cables. These are used to maintain temperatures within the oil pipes at a constant 120°C.
Depending on the size of the cruise liners, between 100 and 250 heating circuits are installed on each ship. Control is provided via Raychem TM-10 surface sensing thermostats.
Each deadline is achieved by Pentair Thermal Management expert Tracer installation teams. Pentair Thermal Management brings 20 years' experience, having installed similar systems on over 40 cruise liners at Meyer Werft and Neptun Werft shipyards since 1992.

TraceTek Detection System Gives Early Alert of Water Leaks
Large museums will often display only a fraction of their exhibits at any given time, with the remainder held in archives. At the National Museum of Korea they are stored in 20 basement vaults that are protected from fire and theft. The biggest potential danger is water ingress and this can ruin the priceless treasures, dating back over 1500 years, in the storage area. Water can originate from the leaks in the plumbing systems or enter through the structural walls and foundation seepage.
The museum need a device that would detect water leaks quickly so operators could take remedial action before irreparable damage was done to the valuable contents.
Pentair Thermal Management installed its TraceTek water leak detection system. At the heart of this system is the TT1000 water sensing cable which will quickly react to the presence of water and trigger an alarm. This is supported with Sensor Interface Modules and a remote control panel that alerts building management staff in the security office and central control room.
The TraceTek system allows building management staff to continuously monitor all 20 of the archive vaults individually for the presence of water in sensitive areas. A leak can be quickly detected and remedied before it’s too late.
TraceTek Detects the 'Weeps' and 'Seeps' that SCADA Systems can Miss
Regulatory pressure and environmental concerns have led operators to take more precautions in high risk areas to detect large leaks. Small leaks may still go undetected since conventionally used SCADA-based CPM systems are unable to detect a leak less than 0.5% of the flow rate. This can be very dangerous since small leaks often grow into larger issues.
A leak detection system can be installed on pipelines spanning many kilometers to detect and closely pinpoint the leak within one meter in both directions.
Pentair Thermal Management offers a TraceTek TT5000 Oil and Fuel Sensing Cable, which detects liquid hydrocarbon fuels without reacting to water.
TraceTek TT5000 is located inside the PVC conduit and is buried in the same trench as the pipework, keeping it protected and secure. The system prevents even the smallest leak from causing damage in the pipeline and surrounding area by quickly detecting and alerting operators to its location.
TraceTek Fast Fuel Sensors Alert Emergency Response Teams Quickly
A refinery in France sought an effective hydrocarbon leak detection system for its fuel storage tank that would immediately alert operators and trigger an emergency response in the event of a leak. Hydrocarbon leaks pose an extreme danger if they’re not quickly detected.
Pentair Thermal Management determined that the refinery needed a fast acting, hyper sensitive device that could detect hydrocarbon fuel spills and not react to water. Oil is often on the surface of rainwater. Sensors that can quickly detect leak detection allow drain valves to close before fuel escapes into storm drains or surface channels
Pentair Thermal Management recommended its TraceTek FFS (Fast Fuel Sensors): fast acting probes for detecting hydrocarbon fuel spills as small as one milometer.
The device’s sensors will trigger an alarm within a few seconds of initial contact. The probes will reset once removed from contact with the oil and fuel residue is easy to clean off, making it easy to reuse them.
TraceTek Sensing Cables will Detect and Precisely Locate Leaks in Hydrant Fuelling Systems.
More and more airports are adopting hydrant fuelling systems with underground fuel lines. The fuel lines pass beneath the thick concrete surface of airport runways, taxiways and aircraft aprons. These systems can have considerable environmental, safety and repair-cost implications if the leak is not precisely located and fixed in a timely manner.
Pentair Thermal Management determined that the airport needed a cost-effective leak detection and monitoring system to accurately monitor and detect fuel leaks.
Pentair Thermal Management installed a TraceTek leak detection monitoring system and its TT5000 sensing cable, which contains a hydrocarbon scavenging material. It’s designed for installation in PVC conduit within the backfill when the fuel pipes are laid down.
If a hydrocarbon leak occurs, the liquid fuel is detected by the cable and drawn into the conduit by capillary action. This triggers an alert via the TraceTek monitoring system, which will pinpoint the location of the leak to within one meter in either direction. Pull boxes (access holes) and connectors allow the system to be inspected in small sections. The TraceTek system quickly detects leaks and alerts engineers of the precise location of the leak, preventing time - intensive excavations of the line.
TraceTek System Will Quickly Detect a Fuel Leak and Alert Operators to Its Location
Oslo Airport realized that a leak in the underground pipe of its hydrant fuel system could result in significant environmental, safety and cost implications since it’s very time intensive to reach the source of the leak underneath the concrete.
Oslo Airport fuel system designers sought a solution that would mitigate safety and environmental risks and offer a more complete leak monitoring solution than periodic hydrostatic pressure checks. The designers needed a system that would immediately detect and pinpoint a leak for operators, enabling them to quickly reduce the implications of the oil leak.
Pentair Thermal Management’ cable-based TraceTek system continuously monitors a pipe to alert operators if a leak is detected within one meter of the location in either direction. The system has TT5000 sensing cable with a hydrocarbon scavenging material that is installed in the backfill of a 42 millimeter slotted PVC conduit when the fuel pipes are laid down.
The TraceTek system quickly reacts to a hydrocarbon leak. The liquid fuel is detected by the cable and is pushed to the conduit by capillary action, triggering an alert via the TraceTek monitoring system.
TraceTek Systems Provide Early Warning of Oil Leaks Into Soil
Coast Oil Co., one of the USA's largest distributors of gasoline, diesel fuel and lubricants, wanted to prevent ground water pollution at its San Jose tank farm and exceed the standards set forth by the Regional Water Quality Control Board.
The facility, consisting of 12 closely grouped small diameter tanks, needed an effective leak detection system to monitor the soil beneath the tanks without interrupting commercial operations. The solution was a complete monitoring solution to detect and signal an alarm. Working within space limitations, engineers used a small, customizable drilling machine.
Pentair Thermal Management recommended its TraceTek leak detection system using TT5000 sensing cable, which contains a hydrocarbon scavenging material.
Installed within PVC conduit in the soil, beneath the fuel tanks, this system quickly detects and signals an alarm if the fuel leaks. Any spillage is drawn into the conduit by capillary action and is absorbed by the cable jacket.
