ERW Pipe Lines STEELEX can deliver ERW pipe production machines covering range from 1/8 (10mm) up to 10 (273 mm) diameter and wall thickness from 0,5 mm up to 12,7 mm. The tubes and pipe of carbon and galvanized steel and even stainless steel can be produced with different type of welding machines and cut by cold saws with the best length and cutting tolerances.
ERW Steel Pipe and Tube, ERW Welded PipeERW Pipe Manufacturering Process:Straight seam high frequency welded pipe (ERW steel pipe) is formed by forming a hot-rolled coil through a forming machine. The skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the pipe blank. Pressure welding is carried out under the action of a squeeze roller.
