CertainTeed Responds to Growing Trenchless Industry with Integral Bell Certa-Lok™ C900 Restrained-Joint PVC Pipe, Larger Diameter Offering


(Valley Forge, Pa.) – Responding to the needs of contractors, engineers and municipalities with growing recognition for the economic and environmental advantages of trenchless pipe installation and replacement, CertainTeed Corporation is expanding its Certa-Lok C900 restrained-joint PVC pipe product line to include an integral bell design option. The company is also adding a 14-inch diameter option to its line of Certa-Lok C905 RJ restrained-joint pipe to meet the growing industry demand for larger size water and sewer pipe system applications.

Available in 4-, 6- and 8-inch diameters, Certa-Lok C900 RJIB (Restrained Joint Integral Bell) features CertainTeed’s time and field-proven mechanical pipe joining system, which utilizes a combination of precision-machined grooves and a nylon spline to provide exceptional tensile strength in pulling or pushing operations. Rounding out the design, a flexible elastomeric gasket within the integral bell provides a solid pressure-certified hydraulic seal.

Unlike HDPE or fusible PVC pipe, Certa-Lok C900 RJIB does not require costly fusion or solvent welding and can be assembled in real time as pullback continues, eliminating the need to string out several hundred feet of pipe within or beyond the work zone.

“Certa-Lok C900 RJIB was designed and subsequently tested to meet the intense performance requirements of municipal water and wastewater system use. At the same time, special attention was focused on clearly understanding the environment of the most demanding trenchless applications, such as static pipe bursting and horizontal directional drilling to ensure that the product met or exceeded the physical requirements of those applications,” said John Coogan, marketing and development manager for CertainTeed’s Pipe Group. “Certa-Lok C900 RJIB has the potential to save municipalities significant time and money, as it can be installed more quickly than fused pipe with much less disruption to surrounding areas, while additionally possessing clear design advantages over competing segmented restrained-joint pipe products.”

The new 14-inch Certa-Lok C905 RJ restrained-joint pipe complements the company’s 16-inch C905 product and marks a verifiable company commitment to product line expansion with larger diameter pipe solutions for projects involving underground drinking water mains, reclaimed water and force main sewers.

“These additions strengthen CertainTeed’s complete line of durable, reliable and easy-to-use restrained joint PVC pipe, providing municipalities, engineers and contractors with the best set of tools for the job,” adds Coogan.
