Heat Treatment /PWHT

HES specializes in performing PWHT for the steel and metal fabrication industries including the construction of pressure vessels, pressure piping, storage tanks, buildings, bridges, offshore platforms, power plants, oil and gas refineries, and petrochemical plants.

PWHT reduces or redistributes the residual stress introduced by the welding process with a technique that involves heating, soaking, and cooling the weldment/machined surface to controlled temperatures.
