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.This low frequencyASTM International - Standards for Steel Pipes,Tubes and The ASTM International specifications for steel tubes list standard requirements for boiler and super heater tubes,general service tubes,steel tubes in refinery service,heat exchanger and condenser tubes,mechanical and structural tubing..Steel Pipes.A53 - A53/A53M-99b - Specification for Pipe,Steel,Black and Hot-Dipped,Zinc-Coated,Welded and SeamlessDifference between ERW,DOM and Seamless Tube Metal May 12,2015·ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding.Seam welding is commonly used during the manufacturing of round,square and rectangular steel tubing.The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding.

ERW/HFW Electric Resistance Welded Steel Pipe/Tube

ERW pipe is the acronym for electrical resistance welded steel pipe,and HFW pipe represents high-frequency welding (HFW) steel pipe tube.The pipes are made from steel coil and the weld seam runs parallel to the pipe.And it is one of the most versatile tools in agriculture,industry,and construction activities.The manufacturing process of ERW steel pipeElectric Resistance Welded Pipe,ERW Steel Pipes,Electric Electric Resistance Welded Pipe.ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes.ERW steel pipe is formed by rolling plate and welding the seam.Flo-Coat&US Wholesale Pipe TubeFlo-Coat process is the superior method of galvanizing steel tubing.It begins with flat strip steel,which is then cold-formed and electric-resistance or induction welded.After welding,the tube receives a triple layer of protection-zinc,conversion coating,and a clear polymer top-coat
