Heating distribution. For commercial, industrial and residential use, engineered PP-R with multilayer faser (MF) can be specified due to its reduced linear expansion, resistance to corrosion and toughness—thus increasing performance and extending the service life of the system. In addition, no chemical treatments are needed for protection. This again saves maintenance costs and reduces waste. Keep in mind, however, that some lower level of chemical treatment may still be needed for metal components in the system.

Small-diameter non-MF coils are available for use in snow-melt applications in soil, concrete or asphalt.

Chilled water distribution. For residential, commercial and industrial use, engineered PP-R pipe has a natural insulation value (estimated 1 or more per inch of pipe wall) that helps reduce heat gain and can eliminate problems with condensation in some cases where metal pipe would require insulation, making it a suitable choice for domestic cold water, cooling towers and condenser water.

Industrial applications. Both green pipe and blue PP-R pipe can be safely used in light industry, heavy industry, automotive mechanic shops and more. Given its resistance to many types of chemicals, PP-R is an appropriate choice for the processing and transport of many aggressive mediums and materials.

Compressed air systems. Both SDR 7.4 PP-R and SDR 11 PP-R piping are used in light or heavy industry, automotive, manufacturing, aviation and other compressed air application in systems.

Longevity and absence of leaks and corrosion make PP-R piping suitable for athletic field and in-floor heating systems.

Snow-melt, turf-warming, in-floor heating systems. With its heat-fused connections, low-pressure drops and extended length tubing coils, PP-R can make a safe and efficient installation under most surfaces, from asphalt and concrete to artificial turf and real grass. Using fusion outlets allows for an extended manifold layout, which helps reduce costs and improve performance.

PP-R pipe can be used in geothermal applications, allowing for horizontal storage of the geothermal mass as opposed to deep vertical wells.
