This Standard provides requirements for heat treatment of piping assemblies that meet the requirements of ASME B31 Code Sections. These requirements apply to:  preheating; postweld heat treatment (PWHT); postforming heat treatment (PFHT) required by the ASME B31 Code Sections for other fabrication processes, including forming processes such as bending; and heat treatments required by contract specifications.<\/p>\n
