When it comes to Post Weld Heat Treatment services, experience is key.

We have many years experience and we have performed quench and tempering, normalizing and other treatments, but by far the primary use of our equipment is for Post Weld Heat Treatment.

This process helps relieve the residual stresses induced from welding and at the same time reduce the weld’s hardness. This improves toughness and ductility. Whether or not a pressure vessel or pipe spool needs PWHT is guided by the ASME code. However, a customer can request it even if it is not required by the code.
