Where ERW Pipe Fits
Electric-resistance welded pipe is the workhorse of water supply, fire mains, scaffolding and structural work. We supply ERW pipe OD 21.3-660mm with wall 1.2-20mm in lengths of 4-12m, with a hot-dip galvanized finish for corrosion protection.
Standards and Grades Covered
Production follows GB/T3091, BS1387, DIN EN10025, EN10219, JIS G3444 and ASTM A53, with API 5L grades A, B and X42-X70 available. Common grades include Q195, Q235, Q345, S235JR, S275JR, S355JR and S355J2H.
Buyer Tip: Specify the Zinc Coating
For exposed or buried lines, specify the zinc coating weight rather than just 'galvanized' - coating options in our supply range cover 40-275 g/m2 for long service life in aggressive soils.
