Turbine Rotor De-Stacks
|
Quickly and safely heat rotor hubs to remove disks from shaft. No need to use gas rings or electrical resistance heaters.
|
Retaining Ring Removal
|
Removal of generator retaining rings and other shrink fit components.
|
Heating of Rotating Parts
|
Pre-Heating and PWHT of rotating components, such as turbine shafts, can be heated inside an Induction coil and monitored with wireless thermocouples.
|
Turbine Bolt Heating
|
De-tensioning and tensioning of turbine bolts. Typical heating time is two to eight minutes per bolt, resulting in significant time saving for client.
|
High Temperature Heating
|
Annealing, solution, and narrow band heat treatment of weldments is performed in a safe and efficient manner. Induction heating negates the need to remove hot electrical resistance heaters from the work piece at high temperatures.
|
Line Thaws
|
Induction cables up to 240 feet in length can be used for line thaws. No need to remove insulation from the line as the coil is placed over the insulation. This reduces set up time and provides a substantial cost saving.
|
Exchanger Bundle Pulls
|
Quick and easy set up assists with the expansion of the exchanger body to allow the bundle to be pulled from the exchanger.
|
Nut Heating
|
Fast heating of nuts on Hydro-Cracker flanges, Reactors, and Exchanger heads allow for quick dismantling of components. Typical heating time is 30 seconds to two minutes per nut. This application helps to eliminate bolt thread damage.
|
Welding Preheat
|
Advanced automated systems control and document welding preheat to reduce thermal stress in three primary ways. First, it drives off moisture that would release hydrogen that could penetrate the steel and cause porosity and subsequent cracking. Second, it reduces heat loss to the surrounding metal, minimizing the rate of weld hardening and allowing hydrogen that is present to escape. And finally, it improves the microstructure and durability of the heat-affected zone.
|
Post-Weld Heat Treatment
|
Carefully controlled PWHT is a crucial step in maximizing the life of your process equipment. PWHT tempers the metal and reduces tensile stresses, minimizing the risk of brittle fracture, stress and corrosion cracking and metal fatigue. This is especially important for equipment used in harsh service environments. Team engineers ensure the structural integrity of the vessel or unit during treatment, and the company’s induction control technology achieves the precise control needed to get the maximum benefit from the treatment.
|
Hydrogen Removal
|
Team can improve the integrity of welded components and minimize the risk of fabrication-related cracking. Used prior to cutting or welding older process equipment, Team’s hydrogen removal technology can help protect equipment during cutting and welding as well as improve the quality of the finished work.
|
Decontamination
|
Induction heating has been successfully utilized to decontaminate storage tanks that once held toxic agents. The heating process drives residual chemical agents off the tank walls so they can be collected, and the tanks can be dismantled.
|
Custom Applications |
There are many other applications where Induction heating can be used when electrical resistance is too slow or impractical.
