Double Socket Coupling Repair Clamps for Plastic Piping

Product Overview

In municipal water supply and wastewater infrastructure, double-socket couplings are the standard fitting for connecting HDPE, PVC, uPVC, and PPR pipes into long-distance conveyance systems. Whether these couplings utilize solvent cement jointing or gasketed push-fit connections, they remain vulnerable to leaks caused by ground movement, thermal expansion, or aging seals. Metalsin’s double-socket coupling repair clamp for plastic piping is specifically engineered to address these critical failure points. Designed for rapid emergency response, this clamp provides a high-strength “wrap-around” solution that allows for under-pressure repairs, eliminating the need for costly pipeline shutdowns or the total replacement of the coupling fitting.

The design of this repair clamp focuses on structural integrity and ease of use in challenging field conditions. It features a robust, two-piece ductile iron body and a precision-engineered rubber gasket system. When the high-tensile bolting mechanism is tightened, the clamp applies uniform radial pressure to fully encapsulate the leaking coupling, creating a permanent, leak-proof seal. To ensure long-term durability and resistance to harsh soil environments, each unit is finished with a fusion-bonded or liquid epoxy coating.
