1 Scope This standard specifies dimension, appearance, weight, technical requirements, test method, test rules, packing, and marking and quality certificate of welded steel pipes for low pressure liquid delivery. This standard is applicable to welded steel pipes for delivering low pressure liquid such as water, air, heating steam and gasses. This standard comprises longitudinal-seam high-frequency electrical resistance welded (ERW) steel pipes, longitudinal-seam submerged arc welded (SAWL) steel pipe and spiral-seam submerged arc welded (SAWH) steel pipe, and respectively marks different requirements related to them. Those without marks are simultaneously applicable to longitudinal-seam high-frequency electrical resistance welded steel pipe, longitudinal-seam submerged arc welded steel pipe and spiral seam submerged arc welded steel pipe.
