Out-of-roundness tolerances apply to maximum and minimum diameters as measured with a bar gauge, caliper, or device measuring actual maximum and minimum diameters.

The average diameter (as measured with a diameter tape) of one end of pipe shall not differ by more than 3/32 in. (2.38 mm) from that of the other end.

Mechanical Tests for API 5L PSL1&PSL2 Grade X42 ERW Carbon Steel Welded Pipe:

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. flattening Test—One flattening test shall be made on specimens from each end of two tubes selected from each lot  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

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.
