PVC-U

Durapipe PVC-U for process chemicals and industrial fluid handling.

Our PVC-U pipe and fittings provide excellent chemical resistance making it ideal for various industrial applications.

PVC-U allows the safe transportation of many acids, alkalis and chemical concentrateswithout fear of corrosion and environmental pollution.

Durapipe PVC-U is a solvent welded, fully matched pipework system incorporating pipe, fittings and valves that is available in both imperial and metric sizes.

PVC-U is lightweight and is extremely easy to install which can save both time and money on any given project when compared to other, more traditional pipework materials.

Furthermore, Durapipe PVC-U is fully WRAS approved and it also meets therequirements of other internationally recognised standards and approvals.

Durapipe UK PVC-U is listed in the List of Approved Products published by the DWI.
