IS 3589 Fe 330 Pipe
Large-Diameter Steel Pipes for Water, Sewage, and Structural Utility
IS 3589 Fe 330 is a standard specification for large-diameter mild steel electric resistance welded (ERW) and submerged arc welded (SAW) pipes. Designed primarily for the conveyance of water, gas, and sewage, the Fe 330 grade refers to the minimum tensile strength of the material (330 MPa). These pipes are widely used in massive infrastructure projects across India, offering a cost-effective solution for high-volume fluid transport and structural piling.
