Manufacturer Seamless Welded Stainless Carbon Alloy Galvanized Square Round Water ERW Steel Pipe
ERW steel 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.
