    a For intermediate grades, the difference between the specified minimum tensile strength and the specified minimum yield strength for the pipe body shall be as given in the table for the next higher grade.b For intermediate grades, the specified minimum tensile strength for the weld seam shall be the same value as was determined for the pipe body using footnote a).

    c The specified minimum elongation, Af, expressed in percent and rounded to the nearest percent, shall be as determined using the following equation:

     

    where

    C is 1940 for calculations using SI units and 625,000 for calculations using USC units;

    Axc is the applicable tensile test piece cross-sectional area, expressed in square millimeters (square inches), as follows:

    1) for circular cross-section test pieces, 130 mm2 (0.20 in.2) for 12.7 mm (0.500 in.) and 8.9 mm (0.350 in.) diameter  test pieces; 65 mm2 (0.10 in.2) for 6.4 mm (0.250 in.) diameter test pieces;

    2) for full-section test pieces, the lesser of a) 485 mm2 (0.75 in.2) and b) the cross-sectional area of the test piece, derived using the specified outside diameter and the specified wall thickness of the pipe, rounded to the nearest     10 mm2 (0.01 in.2);

    3) for strip test pieces, the lesser of a) 485 mm2 (0.75 in.2) and b) the cross-sectional area of the test piece, derived using the specified width of the test piece  and the specified  wall  thickness  of the  pipe,  rounded to  the  nearest  10 mm2 (0.01 in.2);

    U is the specified minimum tensile strength, expressed in megapascals (pounds per square inch).

    Tolerance

    Test Requirement

    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.
