PWHT involves heating the welded component to a specific temperature (typically 1100–1200°F for carbon steel) and controlled cooling. It relieves residual stresses and improves toughness. Mandatory in ASME Sec. VIII: PWHT involves heating the welded component to a
The vessel is filled completely with a liquid (usually water) and pressurized to a minimum of 1.3 times the design pressure (per ASME Sec VIII Div 1). It is safe because water is virtually incompressible; a failure results in a leak rather than an explosion.
Static equipment refers to process equipment that has no moving parts. Its primary functions include storing, containing, separating, or transferring heat/fluids. Common examples:
Radiographic Testing (RT): Uses X-rays or Gamma rays to capture internal structural changes on film. Great for capturing volumetric flaws like slag inclusions or porosity.
