Mechanically restrained joint pipe system from NASP
NASP’s Certa-Lok C905/RJ PVC pipe is a non-metallic mechanically restrained joint pipe system designed for use in potable and reclaimed water, as well as fire protection and force main sewer systems. Available in cast iron outside diameters including 14’’, 16’’, 18’’ and 24’’, the pipe meets all performance requirements of AWWA C905. The pipe provides a restrained joint by utilizing precision-machined grooves on the pipe and in the coupling which, when aligned, allow a spline to be inserted, resulting in a fully circumferential restrained joint that locks the pipes together.
