CPVC Plumbing Systems
Hot and cold water plumbing that resists corrosion and scale, from home bathrooms to industrial process lines - manufactured in Raisen, Madhya Pradesh.
Hot & cold water
CPVC (chlorinated polyvinyl chloride) is a rigid thermoplastic made for water systems that carry both hot and cold water. It does not rust, pit or scale, and its smooth bore keeps flow steady for the life of the building. CANTER CPVC pipes and matching fittings are made by Suvega Innovations at our plant in Pipalkhiriya, Raisen, close to Bhopal.
Sizes & pressure classes
CPVC is made in two size ranges. Small-bore plumbing pipe, 15 to 50 mm (½″ to 2″) in SDR 11 and SDR 13.5, is what plumbers use inside buildings; large-bore industrial pipe, 65 to 200 mm (2½″ to 8″) in Schedule 40 and Schedule 80, is used for risers, mains and process lines.
Small-bore plumbing pipe
Small-bore pipe in two wall classes, for hot and cold water inside homes, hotels and hospitals. Fittings are made to the SDR 11 dimensions.
Large-bore industrial pipe
Schedule 40 and Schedule 80 pipe for larger distribution lines, risers, plant rooms and process piping.

All dimensions in mm. Reference dimensions; pressure ratings are for SDR 11 / 13.5 pipe and fall as temperature rises. Ask us for the sizes and classes currently in stock.
Colour & marking
Tan (cream) is the colour plumbers and site engineers across India recognise as CPVC, and it sets CPVC apart at a glance from grey UPVC pressure pipe and dark-grey SWR drainage pipe. CANTER CPVC follows the same convention: tan pipes and fittings, with a stripe and printed marking that tell you the class.
| Product | Colour |
|---|---|
| SDR 11 pipe (Class 1) | Tan with red stripe |
| SDR 13.5 pipe (Class 2) | Tan with brown stripe |
| Schedule 40 pipe | Tan with brown stripe |
| Schedule 80 pipe | Tan with red stripe |
| Fittings | Tan |
Fittings & valves
Fittings are made to match the pipe, so sockets seat fully and joints stay leak-free.
90° and 45° elbows for changes of direction.
Equal tees, straight couplers and reducer couplers to branch and extend runs.
Unions for easy removal and servicing; end caps to terminate and test lines.
Male and female brass-insert adaptors for taps, mixers, geysers and metal pipe.
Shut-off valves for isolating branches, floors and fixtures.
Step down between sizes without changing the pipe run.
Flanged connections for larger lines and equipment.
Use cement made for CPVC to weld joints into one piece.
Large bore & industrial
Beyond plumbing, CPVC handles hot water, many chemicals and corrosive fluids that would eat through metal pipe. Heavier Schedule 40 and Schedule 80 pipe up to 200 mm is used where lines are bigger and pressures higher.
CPVC vs the alternatives
| CPVC | UPVC | GI / metal pipe | |
|---|---|---|---|
| Hot water | Yes | Not recommended | Yes |
| Rust & scaling | None | None | Rusts and scales over time |
| Weight | Light | Light | Heavy |
| Jointing | Solvent cement - no threading or welding | Solvent cement | Threading or welding |
| Heat loss in hot lines | Low - poor conductor of heat | n/a | Higher - needs more insulation |
| Colour in the market | Tan / cream | Light grey | Silver / galvanised |
Always follow the solvent-cement manufacturer's instructions and local plumbing codes. Our team is happy to help with project-specific questions.
FAQ
Both are rigid, corrosion-free and joined with solvent cement. The main difference is temperature: CPVC is made for hot and cold water plumbing, while UPVC is intended for cold water, agriculture and general pressure lines. In the market CPVC is tan or cream and UPVC pressure pipe is light grey.
Small-bore plumbing pipe from 15 mm to 50 mm (½″ to 2″) in SDR 11 and SDR 13.5, and larger industrial pipe up to 200 mm (8″) in Schedule 40 and Schedule 80. Tell us the sizes you need and we will confirm what is in stock.
CPVC compound is rated for service up to about 93°C. The pressure a pipe can carry falls as temperature rises - SDR 11 pipe is rated 28.1 kg/cm² at 23°C and 7.0 kg/cm² at 82°C - so choose the class for your operating pressure and temperature.
Tan or cream is the standard colour for CPVC in India, which makes it easy to tell apart from grey UPVC pressure pipes and dark-grey SWR drainage pipes on site. A coloured stripe on the pipe shows its class.
Yes, with the right class. Choose SDR 11 or a heavier schedule for higher pressures and follow good practice on supports and thermal expansion. Our team can help you select the class for your building height.
With solvent cement made for CPVC, which chemically welds the pipe and fitting together. Brass-threaded adaptors are used where the plastic line connects to taps, valves and metal pipework, and flanges are used on larger lines.
