NameSPEC 5L, WI 4244, HFW Weld Seam Quality
Start Date02/05/2021
Closing Date03/05/2021
AssociateBenjamin Coco
CoordinatorBenjamin Coco
ProposalWork Item Charge: Address potential low impact toughness concerns pertaining to HFW/ERW testing requirements. Ballot Rationale: Recent weld seam failures in HFW PSL 2 line pipe have been reported. The cause may be attributed to low impact energy. The work group will review API5L quality and testing requirements addressing HFW/ERW weld seams and propose changes as warranted. PHMSA has been requested to provide more details of the failures to properly address the failure mechanism. The concern raised is that current PSL 2 HFW weld line testing requirements are inadequate to safeguard against low impact energy welds and leaks may have occurred consequently. Not initiating action will leave this situation unchanged, and regulatory action could be taken.
