Our PVCu metric pipe is available in sizes 16mm to 315mm with pressure ratings of 10 and 16bar. This is in standard PVC dark grey but is also available as clear pipe.
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.
Metric PVC pipe sizes are slightly different. Although they are also controlled by the outer diameter e.g. a 50mm PVC pipe will always have the same outer diameter, regardless of its pressure class, the expressed measurement IS the outer diameter. So in this example, a 50mm PVC pipe will measure 50mm across its diameter.

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.
