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 advanced PLC and wireless control technology achieves the precise control needed to get the maximum benefit from the treatment.

Line Thawing and Melt-out |
Team electrical resistance heating gets frozen lines flowing again quickly, and keeps them flowing until your plant’s steam tracing system is working again. For foundries that lose a heat source, Team’s combustion services can melt out anything from zinc to steel, 800°F (427°C) to 3,000°F (1,649°C).

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.

Heat Treatment (Annealing and Normalizing) |
Team offers a range of services for annealing and normalizing to alter the properties of metals that may or may not contain welds.
|
Decontamination |
Electrical resistance heating has been successfully utilized to decontaminate huge 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. |
