ERW Pipes
We offer Black and Galvanized Pipes in the widest possible range, manufactured by longitudinal or spiral welding processes such as ERW (Electric Resistance Weld), HFIW (High Frequency Induction Weld), CW (Continuous Weld), SAW (Submerged Arc Weld) etc. Pipes offered have enhanced malleability because of low carbon and manganese contents, dead accurate dimension, and controlled uniform internal weld ridges due to tight tolerances of HR strips and high-tech welding technology. Also the zinc coatings are absolutely uniform, both on inner and outer surfaces. Because of the chemistry and cold working, pipes offer an excellent combination of strength and ductility.
