THOMAS Couplings & Flange Adaptors Restrained Products PIPE PRODUCTS PolyGrip Range Restrained Couplings, Flange Adaptors, End Caps and Harnesses for HDPE and PVC Pipe D1
PolyGrip Range Application Fully restrained connections for HDPE and PVC pipe Application The PolyGrip Range was designed as a simple, high performance end load restraint mechanical method of joining PVC and HDPE pipe. PolyGrip Couplings, Flange Adapters, Fittings and Harnesses are designed to support and grip the pipe, preventing pipe collapse and pipe end pullout. The coupling is suitable for working pressure up to 16 bar (1600 kpa). Advantages The PolyGrip Range includes the following: - Couplings & Step Couplings - Flange Adaptors - Harnesses - Fittings PolyGrip products are supplied assembled and ready to use. The range requires no special skills or complicated tools to install. These products can be installed on site in all weather conditions. It can be installed under wet conditions without shelters, and even under water. It is ideal for on-the-spot repairs, no need for fusion jointing equipment when unexpected problems arise. A PolyGrip Harness enables DI Fittings for PVC pipe to be used as restrained joints with HDPE pipe. Simple Installation Simply cut pipes to length, position ends together and tighten bolts. The self-energizing pressure seal ensures a leak proof joint. The gripping mechanism ensures axial restraint. PolyGrip Harnesses can be installed around existing pipework to prevent PVC Bell & Spigot pipes from separating and PVC / HDPE pipes from pulling out of socketed fittings. Pressure Performance Working Pressure = 16 bar Test Pressure = 24 bar. Size Range - DN63mm - DN315mm Industries - Water Pipe Materials - HDPE - PVC D2

PolyGrip Restraining Harness Specifications Application & Pressure Performance PolyGrip Restraining Harnesses can be used to restrain PVC Pipe Bell & Spigot Joints and PVC pipe repair couplings (5). Working Pressure is dependant on the PVC pipe and differs with each nominal bore (DN). Advantages The gripping action of the restraining harness prevents PVC pipe bell & spigot joints from separating. The restraining harness (1,2 & 3) can be installed around an existing bell & spigot joint (5). Advantages include the elimination of thrust blocks from the pipeline (4). The restraining harness can be used to axially restrain pipe bell & spigot joints as well as fittings. Making pipeline installation faster, more cost effective and simpler.
