Benefit of Material to Systems Application

There is more footage of PVC piping used in the world today than any other piping material mainly due to its durability, safety, ease of installation, cost-effectiveness and environmental soundness.  For these reasons, PVC chilled water piping is an approved material in many commercial and industrial air conditioning systems.  PVC piping has been in use for over 70 years. In North American and Europe there have been several Life Cycle Analysis studies done that have shown that PVC piping compared to other piping materials have a much lighter impact on the environment. Another distinct advantage of PVC in chilled water applications is that PVC’s higher thermal resistance helps keep the chilled water from absorbing heat without the added cost of insulation.  

PVC piping systems are recognized as acceptable for use in chilled water systems in all major model plumbing codes.

System Application and Material Usage

For chilled water applications solid walled pipe either Schedule 40, 80 or constant pressure rated [(Standard Dimensional Ration (SDR)] is used. Solvent cementing is the most commonly used method of joining these piping systems.

Pipe diameters are available from 2” to 24” and in 10 or 20 foot lengths. Pipe ends are either plain end, belled or grooved. The grooved-end pipe is joined by using an elastomeric coupling.  If the piping is used in outdoor environments, it is advisable to protect the pipe from the sun rays with an approved shield. The most commonly used protection is a coat of water-based latex paint.

For most chilled water applications solvent cementing is used almost exclusively. Cemented joints are easy and safe to make requiring no expensive or special tools. The joint, if made properly, it is stronger than the pipe or fitting.

To ensure a leak-free system, completely follow the manufacturer’s joining and installation instructions. In testing any PVC piping systems, test hydrostatically—DO NOT TEST WITH AIR.

Most chilled water systems are closed-loop and often contain bactericides or chemical treatment compounds. Make sure these additives are compatible with the PVC piping system.  Other alternate chilled water piping materials are steel, cast iron and copper. If conditions of service allow the usage of PVC piping material, it likely would be the most cost-effective of any piping material. For more information visit the PPFA Website.
