SANS 719 WELDED PIPE
A SANS 719 welded pipe is manufactured from high-quality mild steel using Electric Resistance Welding (ERW) techniques. These pipes are designed for medium-pressure applications and are ideal for industrial, and fluid transfer use. They are compliant with South African National Standards (SABS/SANS 719) and can be supplied in plain, threaded, or galvanised formats.
