The difference between ERW, SSAW, LSAW(UOE) Steel pipe Apr 22, 2018 · Straight seam high-frequency welded pipe (ERW) is divided into two types of induction welding and contact welding according to different welding methods. Hot-rolled wide-gauge steel coil is used as raw material, after pre-bending, continuous forming, welding, heat treatment, sizing, straightening, Cutting and other processes, compared with spiral welded pipe with a short weld, high Codes defination for steel tubes and pipes - meco websiteA cold rolled steel can be either a mild steel or a high carbon steel. Can also be termed as ERW (Electric Resistance Welded). See ?ERW Hot Rolled Electric Welded (HREW) Hot rolled steel is steel that is rolled to size in the mill while red hot. Hot rolling steel does not work harden it as much as cold rolling. For this reason, hot rolled steel Cold Formed Hollow Section Fabrication ERW, LSAW, SSAW LSAW pipe diameter ranges are larger than ERW steel pipe (approx. 1660 inches). Two benefits LSAW steel pipes offer are low-temperature erosion resistance and high-pressure resistance. Spiral Submerged Arc-Welding Pipe (SSAW), also known as HSAW pipe, is created using the same welding technique as the LSAW pipe.
