Post-Weld Heat Treatment

Post-Weld Heat Treatment is a critical thermal process used to reduce residual stresses, improve ductility, and enhance the overall toughness of a welded joint. By heating the material to a specific temperature below its transformation range and holding it for a set duration, PWHT prevents hydrogen cracking and ensures the weld can withstand high-pressure or high-temperature environments. This category features high-performance Induction Heating Systems, Ceramic Heating Pads, and Digital Temperature Controllers designed for precision and uniformity. Essential for compliance with ASME and API codes, our PWHT equipment provides the reliability needed for the construction and maintenance of pressure vessels, pipelines, and heavy structural steel.
