February 2015 Pipes, Fittings & Valves Imperial and Metric Systems Durapipe PVC-U including Guardian dual contained pipework Technical Data First In PVC First In PVC INDUSTRIAL FLUID HANDLING Durapipe PVC-U – for process chemicals and industrial fl uid handling. Our PVC-U pipe and fi ttings provide excellent chemical resistance making it ideal for various industrial applications. PVC-U allows the safe transportation of many acids, alkalis and chemical concentrates without fear of corrosion and environmental pollution. Durapipe PVC-U is a solvent welded, fully matched pipework system incorporating pipe, fi ttings 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 the requirements of other internationally recognised standards and approvals. Durapipe UK PVC-U pipe is listed in the ‘List of Approved Products’ published by the DWI.
