API 5L X65 PSL1/PSL2 LSAW Carbon Steel Pipe is usually used in projects of oil and gas pipeline , in submarine pipeline, pipelines through high-altitude zones and dense urban areas.

API 5L X65 PSL1/PSL2 LSAW Carbon Steel Pipe is manufactured by forming the X65 steel plates into a round shape then welding the seam through automatically arc welding process. In the production of API 5L X65 PSL1&PSL2 LSAW Carbon Steel Pipe, plates of grade X65 are formed by the molding machine into round shape then welded through double-sided submerged arc welding.

Manufacture:Longitudinally Submerged Arc Welding

Size: O.D.: 406~1422mm  W.T.: 8~60mm          

Length: 3-12M or specified length as required.

Ends: Plain End, Beveled End, Grooved

Notes:

1. Weight tolerances apply to the calculated weights for threaded-and-coupled pipe and to the tabulated or calculated weights for plain-end pipe. Where negative wall thickness tolerances smaller than those listed in above table are specified by the purchaser, the plus weight tolerance for single lengths shall be increased to 22.5 percent less the wail thickness negative tolerance.

2. For carloads composed of pipe from more than one order item, the carload tolerances are to be applied on an individual order item basis.

3. The tolerance for order items apply to the overall quantity of pipe shipped for the order item.

Tensile testing of the pipe body—The tensile test should be carried out in accordance with ISO6892 or ASTM A370.Longitudinal samples should be used.Twice per test unit of pipe with the same cold-expansion ratio a.b.d.

 CVN impact test—The Charpy test should be carried out in accordance with ASTM A370. Twice per test unit of not more than 100 lengths of pipe with the same cold-expansion ratio a.b.d.

 Hardness Test—When suspected hard spots are detected by visual inspection, hardness tests shall be carried out in accordance with ISO 6506, ISO 6507, ISO 6508 or ASTM A 370 using portable hardness test equipment and methods complying with ASTM A 956, ASTM A 1038 or ASTM E 110 respectively depending on the method Used.

 Hydro-static Test—Each tube shall be subjected to the hydro-static pressure test

 Bending Test— a sufficient length of pipe shall stand being bent cold through 90° around a cylindrical mandrel.

100% X-ray test for the weld seam

The ultrasonic testing

The eddy current examination

A sufficient number of visual surface imperfections to provide seasonable assurance is necessarily. The defect shall be removed or cut off within the limits of requirements on length . The finished pipe shall be reasonably straight.
