E.) DWT Test For PSL 2 Welded Pipe F) Micro Test G.) Macro Test H.) Chemical Analysis

The document lists testing requirements for mother pipes, including references to standards like API 5L, ISO 3183, and MSS-SP-75. It outlines non-destructive testing like visual inspections, dimensional checks, ultrasonic testing, and radiographic testing of welds according to relevant code sections. Mechanical tests like hardness testing, impact testing, bending, and tensile tests are also specified to evaluate properties of the base metal, heat-affected zone, and welds. Chemical analyses must further be conducted.
