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.
