CertainTeed CertaFlo™ Greenline™ PVC pipe features Certa-Lok™, the industry original non-metallic mechanically restrained joint system designed for use in gravity sewer systems. CertaFlo™ Greenline™ 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 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 CertaFlo™ Greenline™ include:
 
• Horizontal directional drilling (HDD)
• Static pipe-bursting
• Open-cut
• Laser Guided Boring (Vermeer)

Standard pipe color for Gravity Sewer Applications is GREEN.
