API 5L Pipe Specification (PSL1, PSL2, SOUR SERVICE)
-We are a global exporter
Longma produces and stocks API 5L line pipes with grade B and X42-X80.
ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas. For material use in a sour service application, refer to Annex H; for offshore service application, refer to Annex J of API 5L 45th Edition.

*Out Diameter: 60.3-1,829mm(2″-72″)
*Wall Thickness: 3.91-50.8mm(0.154″ – 2″)
*Length: 3-18 meters
Bare surface, Black painting, Coating(FBE, 2PP, 2PE, 3LPE, 3LPP, Zinc-rich epoxy primer coating).
Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Jointers need not be hydrostatically tested provide the pipe sections used were successfully tested.
No cracks shall occur in any portion of the test piece and no opening of the weld shall occur.
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 walls, 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.
