ERW PIPES & TUBES

24"X6.35MMX20FT BLACK WELD STEEL TUBES FOR OIL

Electrical Resistance Welding (ERW) A controlled high precision welded steel pipes formed by rolling hot rolled coil (HRC) and welding is the seam with High Frequency Induction Heating (HFI) process. Pressure is used to forge the material under elevated temperature to melt together, and no filler material is added to the weld (only Forging). The welding apparatus contains an induction coil that is energized with a high-frequency electric current. This generates a high-frequency electromagnetic field that acts on work piece with no contact between the coil and the pipe surface. ZS Steel main activities include Manufacturing of Black and Galvanized ERW steel pipes in size range (1/2”–20”) for Oil & Gas Pipelines, Water Pipelines, Oil Well Casing, Water Well Casing, Chilled Water Systems, Fire Fighting Systems, Pump Column Pipes, Piling, Industrial Frames, Fencing, Scaffolding, Water Irrigation, Cars Exhaust, Decoration, Furniture, Ceiling and other many other industrial and Construction applications.
