Postweld Heat Treatment Code Exemption - Pt 1 - TWI


Postweld Heat Treatment Code Exemption - Pt 1 - TWI

Post-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, t…See more on twi-global.comsp.info API 620, 10th Ed, Add 1 (Committee)Tanks API STANDARD 620 TENTH EDITION, FEBRUARY 2002 ADDENDUM 1, JUNE 2004. e Use Only. e Use Only Design and Construction of Large, Welded, Low-Pressure Storage Tanks Downstream Segment API STANDARD 620 TENTH EDITION, FEBRUARY 2002 ADDENDUM 1, JUNE 2004. e Use Only SPECIAL NOTES
