Standard Pipe Showdown Continuous Weld vs.Electric sp.infoApr 25,2013·Nick LaMonto,piping superintendent at Chicago-based Atomatic Mechanical Services,threads pipe every day.As an experienced piping professional,he knows the importance of tool longevity and what it can cost when working with an inferior product.We put Nick’s machines to the test,threading both types of steel standard pipe continuous weld and electric resistance weld.First up,Nick Electric Resistance Welded - an overview ScienceDirect

Preferential corrosion attack in the weld area,leading to premature leaking,was observed in electric resistance welded (ERW) of carbon and low alloy steel pipes exposed to neutral salt-containing waters [4].The selective and localized corrosion prefers to occur in the weld,especially close to the fusion line.ERW seams in the presence of a corrosive environment are susceptible to preferential attack at the

A Study of Metallurgical Factors for Defect Formation in sp.infoMay 12,2015·Electric resistance welding (ERW) is widely accepted due to its low cost and high efficiency of production as a conventional manufacturing technology for the steel pipes.However,ERW pipes are vulnerable to the defect formation because its welding zone has different characteristics compared to the base material.Cited by 6Publish Year 2015Author Min Sung Joo,Kyung-Min Noh,Wan-Keun Kim,Jin-Ho Bae,Chang-Sun LeeElectric Resistance Welded (ERW) Pipe The Macomb Group
