The welded seam of electric weld pipe is heat-treated after welding to a minimum temperature of 1,000°F or processed so that no untempered martensite remains.Such differences of erw are usually eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process,which is mandatory for API grades L80,C90,T95,and P110.ERW Pipes,HFW Pipe Manufacturer SupplierThe High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe,it's manufactured by cold-forming a sheet of steel into a cylindrical shape.Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.ERW Steel Pipe,HFW Steel Pipe,Black ERW Steel Pipe,ERW High-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine,the use of high-frequency current skin effect and proximity effects,the tube edge heating and melting,squeeze roller under pressure welding to achieve production.
As the ERW steel pipe with easy control of rolling,with the welding technology and on-line heat treatment technology,the performance of the weld can be controlled,so straight seam welded steel pipe elongation than seamless steel pipe 8% -10% higher,which Is because the straight seam electric-welded pipe carbon content of less than 12% lower than the seamless tube.ERW/LSAW Welded Steel Pipe General Welded Pipe VS Straight seam welded pipe - Piping Straight seam steel pipe definition Refers to the longitudinal and parallel steel pipe of the weld.It is also commonly referred to as a straight seam welded pipe or a straight seam steel pipe.The straight seam steel pipe is made by winding a long strip of certain specifications through a high frequency welding unit and welded by a straight seam.
