Welded pipe is produced from steel sheet by electric resistance welding process. Welded pipe does NOT have a weld seam inside or outside.
Non-alloy steel tube suitable for welding or threading, with hot coated inside and outside zinc coating with various edges treatment, tested for permeability. Wall thickness - M (Medium). Nominal length 6m.
Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. The electric current can be supplied to electrodes that also apply clamping pressure, or may be induced by an external magnetic field.
