    tástáil Riachtanas

    Hydrostatic test

    Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Jointers need not be hydrostatic tested provide the pipe sections used were successfully tested.

    Bend test

    No cracks shall occur in any portion of the test piece and no opening of the weld shall occur.

    Flattening test

    Acceptance criteria for flattening test shall be:

    • EW pipes D<12.750 in:
    • X60 with T 500in. There shall be no opening of the weld before the distance between the plates is less than 66% of the original outside diameter. For all grades and wall, 50%.
    • For pipe with a D/t > 10, there shall be no opening of the weld before the distance between the plates is less than 30% of the original outside diameter.
    • For other sizes refer to the full API 5L specification.

    CVN impact test for PSL2

    Many PSL2 pipe sizes and grades require CVN. Seamless pipe is to be tested in the body. Welded pipe is to be tested in the body, pipe weld and heat-affected zone. Refer to the full API 5L specification for the chart of sizes and grades and required absorbed energy values.
