Scope

This standard specifies the dimension, appearance, weight, technical requirements, test
method, test rules, packing, 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 we2ded (SAWL) steel pipe, and
spiral-seam submerged arc welded (SAWH) steel pipe. And it denotes the different
requirements to each of them respectively. 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.
