Weld Procedure Specification & Flaw Acceptance Criteria for a Brine Pipeline

A cement-lined, brine carrying piping system was proving difficult to weld, especially the weld root pass. APTECH worked with this government client to develop a welding procedure specification (WPS) that would minimize weld root discontinuities. In parallel, we performed fracture mechanics calculations to provide the client a flaw acceptance criteria which removed unneeded conservatism in the existing workmanship standards.
