Pipeline Transportation API 5L ISO 3183 PSL1 ERW Steel Pipe
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. In Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion, hook cracks, and inadequate bonding of the seams, so low frequency ERW is no longer used to manufacture pipe. The high frequency process is still being used to manufacture pipe for use in new pipeline construction.
