For transverse strip tests, a deduction for each 1/32-in. (0.8-mm) decrease in wall thickness below 5/16 in. (7.9 mm) from the basic minimum elongation of the following percentage shall be made 1.25 1.00 1.00
A The minimum elongation in 2 in. (50 mm) shall be determined by the following equation:
e=625000A 0.2 / U 0.9
for inch-pound units, and
e=1940A 0.2 / U 0.9
for SI units,
where: e = minimum elongation in 2 in. (50 mm), %, rounded to the nearest 0.5%, A = cross-sectional area of the tension test specimen, in.2 (mm2), based upon specified outside diameter or nominal specified outside diameter or nominal specimen width and specified wall thickness, rounded to the nearest 0.01 in.2 (1 mm2). (If the area thus calculated is equal to or greater than 0.75 in.2 (500 mm2), then the value 0.75 in.2 (500 mm2) shall be used.), and U = specified tensile strength, psi (MPa).

Test Requirement

In addition to ensuring chemical composition and mechanical properties, hydrostatic tests are performed one by one, and flaring and flattening tests are performed. . In addition, there are certain requirements for the microstructure, grain size, and decarburization layer of the finished steel pipe.
