Heat treatment

Full suite of services to efficiently reduce stress and enhance material properties. 

Weld integrity

During the welding process there is a lot of opportunity for stresses to build up. High residual stress can be a source of corrosion and cracking, while also creating brittleness. Hydrogen-induced cracking is another risk to be reckoned with during welding. All these factors can severely reduce the life-span on the welded component (pipe, structure, equipment). 

Controlled heat

We can provide the full suite of heat treatment services. This includes: 

  • Pre-heating and post weld heat treatment (PWHT).

  • Metal properties enhancement (e.g. normalizing, annealing).

  • Specialty services (e.g. dewaxing, refractory dry-out, debolting).

In this way stresses can be reduced, hydrogen removed, ductility and toughness increased and hardness reduced.
