Selecting the appropriate plastic pipe material for hot and cold water distribution within buildings is crucial for long-term system performance and water quality.
Key Properties
CPVC (Chlorinated PVC) is widely used for Hot and Cold water applications. It finds significant use in regions such as the USA and India. A key advantage of CPVC in these applications is that it does not require a barrier layer to prevent oxygen diffusion, unlike Polyolefin (PO) pipes (like PE) which often need one to protect system components from rust caused by oxygen in the water. CPVC joints can be readily cemented. While ABS can be used for hot water drainage in some cases, it requires careful consideration of simultaneous cold water addition and is not UV-resistant.
Applications
CPVC is a preferred material for residential, commercial, and industrial systems delivering both heated and chilled potable water.
FAQ Section
Why is CPVC suitable for both hot and cold water?
CPVC is specifically formulated for use across a range of temperatures for potable water distribution.
Do CPVC pipes need a barrier layer like some other plastic pipes?
No, CPVC does not require a barrier layer to prevent oxygen diffusion, unlike some PO pipes used for similar hot/cold applications.
