CertainTeed Yelomine™ PVC pipe features Certa-Lok™, the industry original non-metallic mechanically restrained joint system designed for use in force main sewer systems. Yelomine™ PVC pipe is made in iron pipe size (IPS) outside diameters and meets all performance requirements of ASTM D2241.
Certa-Lok™ pipe provides a restrained joint by utilizing precision-machined grooves on the pipe and in the coupling/integral bell which, when aligned, allow a spline to be inserted, resulting in a fully circumferential restrained joint that locks the pipes together. A flexible elastomeric seal (O-ring) in the coupling and/or integral bell provides a hydraulic seal.
Note: If needed, the joint can be disassembled and re-used to allow for system changes, extension or removal for re-use. Certa-Lok™ joints can be easily disassembled, allowing for system changes, extension, movement or reuse of the entire system.
Typical installation methods for Yelomine™ include:
• Horizontal directional drilling (HDD)
• Static pipe-bursting
• Open-cut
In addition to traditional municipal water systems, Yelomine™ may also be used in applications involving or requiring:
• Potable and reclaimed water systems
• Restrained, non-metallic change-of-direction fittings
• Elimination of concrete thrust blocks.
• PVC carrier pipe placed inside steel (or other) casing pipe
• Steep or extreme grade changes
Standard pipe color for Force Main Sewer Applications is GREEN.
Green Yelomine is available by special order only.
