Difference between ERW and EFW steel pipes Hebei Haihao

ERW steel pipe is the abbreviation of resistance welding.The welding methods of ERW pipe and submerged arc welded pipe are obviously different.Pressure welding without filler metal is adopted.The skin effect and proximity effect of high frequency current are applied to the edge of instantaneous heating plate.ASTM A53 Grade B ERW Steel Pipes.ERW Steel Pipe API 5L ASTM A53-Threeway Steel Co.ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through an electric charge.ERW are used for mechanical and pressure applications,and for ordinary uses in steam,water,gas and air lines.More than 350 different combinations of finish,end treatments and lengths are available Electric resistance welded (ERW) pipe ASTM A234 butt Electric resistance welded (ERW) pipe is 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.Initially this manufacturing process used low frequency A.C.current to heat the edges.
