Postweld Heat Treatment Code Exemption - Pt 1 - TWI
AbstractIntroductionReview of Current Practice and Code RequirementsPost-weld heat treatment (PWHT) is applied to steel assemblies primarily to reduce the likelihood of brittle fracture by reducing the level of tensile welding residual stresses and by tempering hard, potentially brittle, microstructural regions. For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels anEN 10028-2 P265GH Weld Neck Flange,P265GH Plate FlangesC&N is a professional manufacturer of ASTM A105N Weld Neck Flange,A105 Welding Neck Flange,WNRF Flange,ASME B16.5,ASME B16.47 Weld neck flange,EN 1092-1
