Scope: This standard specifies the evaluation method for hydrogen-induced cracking (HIC) caused by corrosion hydrogen absorption of pipeline steel and pressure vessel steel plate, flange and pipe fittings in a corrosive environment containing sulfide aqueous solution. This standard provides the size, quantity, location, and orientation of samples to be taken from each steel product type, including steel pipes, plates, fittings, and flanges. This standard covers special procedure requirements for small diameter (nominal diameter [DN] 50 to 150, nominal pipe size [NPS] 2 to 6), thin wall (wall thickness not greater than 6 mm) electric resistance welded (ERW) and seamless steel tubes . Unless otherwise specified in this standard, these small-diameter, thin-walled materials should be tested in the same manner as other steel pipes. This standard does not contain acceptance or rejection criteria, but Chapter 8 of GB/T 20972.2-2008 provides guidance.
