Welded Steel Pipe (WSP)

Welded Steel Pipe (WSP) consists of a steel cylinder lined with cement mortar and coated with a dense cement mortar. An easily assembled watertight joint is provided by using bell and spigot steel joint rings welded to the ends of the cylinder and sealed with a confined round rubber gasket. Larger diameters, other lengths and designs for greater operating pressures and a wide variety of coatings and joint configurations are also available.

WSP is supplied in standard diameters 16" through 144", thicknesses up to 1 1/4" and a standard lay length of 40 feet for operating pressures up to 500 psi.
