The Differences Between UPVC & PVC PipesWhat is the difference between UPVC AND CPVC AND PVC pies, anyone can tell appropriate use of each pipes?CPVC is a popular engineering material due to its relatively low cost, high glass transition temperature, high heat distortion temperature, chemical inertness, and flame and smoke properties.
CPVC is used in a variety of industrial applications where a high functional temperature and resistance to corrosive chemicals are desirable. Besides pipe and fittings, it is used in pumps, valves, strainers, filters, tower packing, and duct, as well as sheet for fabrication into storage tanks, fume scrubbers, large diameter duct, and tank lining.
Pipe:
In use as plumbing materials, CPVC exhibits comparatively high impact and tensile strength and is non-toxic.
In pressurized systems, it can be used with fluids up to ) higher, contributing to its popularity as a material for water piping systems in residential as well as commercial construction.
uPVC or Rigid PVC is often used in the building industry as a low-maintenance material, particularly in Ireland and the UK, and in the United States where it is known as vinyl, or vinyl siding.
The material comes in a range of colors and finishes, including a photo-effect wood finish, and is used as a substitute for painted wood, mostly for window frames and sills when installing double glazing in new buildings, or to replace older single glazed windows. It has many other uses including fascia, and siding or weatherboarding. The same material has almost entirely replaced the use of cast iron for plumbing and drainage, being used for waste pipes, drainpipes, gutters and downpipes.
In pressurized systems, it can be used with fluids up to 80°C and higher in low-pressure systems. It does require specialized solvent cement for assembly. Depending on local building codes, it can be used in hot and cold water systems as well as hot and cold chemical distribution systems in conditions where metal pipe is not indicated.

CPVC can withstand corrosive water at temperatures greater than PVC, typically 40°C to 50°C (70°F to 90°F) higher, contributing to its popularity as a material for water piping systems in residential as well as commercial construction.
