The Steel Advantage
Steel pipe's inherent strength means less wall thickness is required to accommodate working pressure and capacity requirements than competing materials. This translates into transportation and installation savings. Because Northwest Pipe offers engineered systems, lengths can be customized to minimize the number of field joints required, further reducing costs. Steel pipe's leak-proof design and high safety factor mean fewer operating troubles. Steel pipe has the best performance of all pipe materials in seismically active zones.

The Water Pipe Design Manual includes an extensive collection of technical information on steel pipe. Registration opens the door to information on pipe design, joints, linings & coatings, corrosion protection, and an extensive collection of suggested specifications for various lining and coating combinations.
