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.
