Our PVCu pressure pipe is available in sizes 1/2" to 8" in classes C, D, E and 7.
As a material, polyvinyl chloride - unplasticised has a wide temperature and pressure range, coupled with great chemical resistance, meaning it can be relied upon in a number of applications, such as water treatment, heating, cooling, chemical and industrial fluid handling, and effluent treatment. As PVC is odourless and tasteless, it is also ideal for transporting potable water.
Imperial PVC pipe sizes are expressed by the nominal bore of the pipe, which is an approximation of the internal bore. In reality, a 3" PVC pipe will not measure 3" internally, for example. However, a class C 3" pipe will have exactly the same outer diameter as a class D 3" pipe, and the same as any other 3" PVC pipe. This is because the wall thickness of the pipe governs the pressure, and allows any 3" PVC pipe to fit in any 3" PVC pipe fitting.
