Certa-Lok C900-RJ PVC Water Pipe
CertainTeed Certa-Lok C900/RJ™ Restrained Joint PVC pipe is the first non-metallic joint restraining system designed for use in municipal water and fire protection systems and other restrained joint applications.
The inability of some soils to support thrust blocks, coupled with the increased demands placed on utility corridors, resulted in the development of Certa-Lok C900/RJ™ Restrained Joint PVC pipe (with cast-iron ODs), which meets all performance requirements of AWWA C900. Certa-Lok C900/RJ™ Restrained Joint PVC pipe is desined to eliminate costly concrete thrust blocks in a properly engineered water system.
