HAL's vastly experienced personnel using our High Velocity Burners can perform Post Weld Heat Treatment for a large variety of tanks, LPG bullets, pressure vessels, spheres and welded fabrication structures. One of the ways this is achieved is by constructing a temporary furnace around the items to be treated. The other way is to apply insulation directly onto the outer surface while turning the item into its own furnace, thereby ensuring the achievement of a uniform temperature so that even the highest standards and specifications are comfortably satisfied.
