ERW Pipe is the abbreviation for Electric Resistance Welded Pipe, which refers to a steel pipe with a longitudinal seam formed and welded from hot-rolled coils using high-frequency electric current.

Core Features

  • Low Cost: Cheaper than seamless steel pipes and highly efficient to produce.

  • High Precision: Good dimensional control and uniform wall thickness.

  • Reliable Weld: Modern high-frequency welding technology ensures weld strength close to that of the base metal.

Common Standards & Grades

  • API 5L: Line pipe (GR.B, X42, X52, X60)

  • GB/T 3091: Fluid conveyance pipe (Q235B, Q355B)

  • ASTM A53: Structural/low-pressure fluid pipe

Main Applications

  • Oil/Gas & Fluid Transport: Oil, natural gas, water, gas pipelines

  • Structural Engineering: Building steel structures, scaffolding, tower crane supports

  • Piling Engineering: Building foundations, dock piling

  • General Industry: Mechanical structural parts, greenhouses, wire conduits
