Choose Aquatherm polypropylene pipe, or PP-RCT & PP-R pipe, for pressurized mechanical and plumbing systems of all sizes from the leading polypropylene manufacturer.
Polypropylene (PP) is a versatile piping material that is used in a wide range of applications. Two types of PP are used for pressure piping systems: PP-R (polypropylene random copolymer) and PP-RCT (polypropylene random copolymer with modified crystallinity and temperature resistance).
Both PP-R and PP-RCT piping products are rated for pressurized operation at 180ºF (82ºC) temperature. When SDR 9 (or thicker) wall type is selected, these materials are rated for 100 psi at 180ºF (690 kPa at 82ºC), meeting the requirements of national model plumbing codes.
PPR pipes can withstand temperatures up to 70°C, while PPRCT pipes are suitable for temperatures up to 95°C. How do the costs of PPR and PPRCT pipes compare to other materials? PPR and PPRCT are often more cost-effective than copper and offer lower long-term maintenance costs than PVC and CPVC.
17 cze 2024 · Polypropylene random copolymer with modified crystallinity and temperature resistance (PP-RCT) is the newest generation of polymer piping materials manufactured to provide greater durability and long-lasting service for domestic water and hydronic heating and cooling applications.
Temperature Range. PP-H: –5oC to 90oC (23oF to 194oF) PP-R: –20oC to 90oC. Polypropylene is a member of the polyolefin family and is used in a wide variety of applications from acids and alkalies to organic solvents and even pure water.
