NameSPEC 5L, WI 4250, Annex K Lamination Control
Start Date02/19/2021
Closing Date03/19/2021
AssociateBenjamin Coco
CoordinatorBenjamin Coco
ProposalRevise the requirements for UT control for laminations in Annex K to allow, if agreed, ultrasonic inspection of the strip/plate body and edges with automated systems in accordance with ISO 10893-9 to verify that the strip/plate body and edges are free of laminar defects specified in K.2.1.1, in lieu of ultrasonic inspection at pipe ends as specified in K.2.1.2. The reason for the proposed action is that there are customers that requires UT control for laminations of the strip/plate body and edges with 100 % coverage. These customers would be open to wave the ultrasonic inspection of the pipe ends as specified in K.2.1.2, because it becomes redundant, if 100 % of the strip/plate surface has been inspected. Duplicating the inspection adds unnecessary impacts.
