Our PVC-U pipes offer a range of key benefits for use across the water industry, including fatigue resistance and strength that ensures a long service life in water appliions. PVC-U is lightweight and offers an extremely smooth bore together with precision joints, providing unrivaled hydraulic capacity.

The cement also allows more water to be absorbed, which can hurt the integrity of the pipe. Insufficient cement use will also be problematic, as it makes the bond too weak. Use enough cement to create a complete bond on the inside of the fitting and the outside of the pipe, but not enough that it …

If the pluing is installed using non-metallic PVC pipe then it cannot be used as a reliable source for a ground bond, so the ground wire should be taken back to the panel is where it may be bonded with the home ground system.

There are several reasons for this. Firstly pvc is much lighter, stronger and can be made in much longer lengths. If pvc is compressed it simply distorts slightly and if the compression relaxes it will go back to its original shape. Metal once comPuhui Pipe manufacturer in China

PVC pipe thus is used to carry water, while PVC conduit typically works as housing for wiring. PVC pipe may be used in place of PVC conduit if the PVC pipe has been manufactured to meet safety requirements on flame and temperature resistance, but because PVC conduit isn''t pressure tested, PVC conduit cannot replace PVC pipe.
