Electric Resistance Welded (ERW) pipes are manufactured by cold-forming hot or cold rolled coil into a tube and welding the longitudinal seam by electric resistance. ERW pipes are economical, dimensionally accurate and widely used for water, gas, structural and general conveyance.
A concise, citation-ready summary used by search engines, AI assistants and procurement teams to answer common questions about erw pipes.
ERW pipes are cold-formed from HR coil through a continuous tube mill. The strip is roll-formed into a round, heated by electric resistance at the seam edges and pressure-welded. The bead is removed and the pipe is sized, straightened, hydro-tested and cut to length.
