ERW Steel Pipes

Overview:
Electric‑Resistance‑Welded (ERW) steel pipes are manufactured by high‑frequency resistance welding of rolled steel strips or steel plates.
These welded steel pipes are widely applied for the transportation of oil, natural gas and chemical media. They are also extensively used for structural purposes in urban building projects, offshore constructions and general mechanical applications, including square & rectangular hollow sections.
Our ERW steel pipes comply with major international standards: DIN 2448, BS1387, EN 10255, EN10219, EN10217‑1, API Spec 5L, API 5CT and ASTM A53/A53M. Outside diameter ranges from 21.3 mm up to 339.7 mm. We supply both black plain pipes and hot‑dip galvanized pipes.
