PWHT on spherical Tank

Post Weld Heat Treatment ( PWHT) reduces the residual stresses formed during welding. It also restores the macro structure of the steel. Mandatory in high pressure applications, constructors have to strictly follow PWHT requirements to avoid component failures. This process is technically done by famous company because its costly and sensitive projects. our experiences in PWHT on spherical vessels betrayed that this company is one of the best in the world.
