Post-weld Heat Treatment

Carefully controlled post-weld heat treatment (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. Our 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.
