Differences Between ERW and LSAW Steel Pipe

Sep 24, 2020Straight seam welded steel pipes are divided into high frequency resistance welding and submerged arc welding according to the welding process. Straight seam submerged arc welding is referred to as LSAW, and longitudinal high frequency resistance welding is referred to as ERW.(plate) What is LSAW welding?What is LSAW welding?Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.Difference between ERW Pipes, SSAW Pipes and LSAW Pipes erw welded steel pipes longitudinally welded pipes lsaw(plate) What is a differently SSAW pipe?What is a differently SSAW pipe?Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line.What is The Differences Between LSAW Pipe and SSAW Pipe
