Difference between Seamless ERW Stainless Steel pipe

Nov 24,2014·Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length.Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section,while seamless pipe does not have any joint in its cross-section through-out its length.ERW Steel Pipe,China Electrical Resistance Welded Pipe ERW steel pipe is a straight seam electric resistance welded pipe,a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe.It has sturdy frame which is strong enough to make sure the stable operation.And it is resistant to water,oxygen and corrosion,which is endurable with long life span.ERW Straight Seam Welded Tube Surface Quenching Heat ERW straight seam welded pipe surface quenching and tempering heat treatment is usually carried out by induction heating or flame heating.The main technical parameters are surface hardness,local hardness and effective hardened layer depth.

What is Common Defects for Welded Steel Pipes - Octalsteel

Common defects for welded steel pipe.We will take a look at some common defects that occur on welded steel pipes and they are explained below 1.Lack of fusion.This is simply the poor adhesion of the weld bead to the base metal.A weld bead that doesnt begin at the weld grooves root is known to be incomplete penetration.What is EFW steel pipe - pipelinedubaiThis is a seamless,straight-seam welded,and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.Chromium content ranges from 15 to 26 Percent.Available Stainless Steel Grades are ASTM A312 TP304,304H,304L,310,316,316H,316L,317,321L,321,321H,347,347H.
