If you’re familiar at all with PP-R piping systems, you’re probably aware that POLOPLAST pipes offer some significant advantages over metal pipes, including a longer lifespan. One technical detail that sometimes gets overlooked, though, is the volumetric flow rate of our PP-R piping systems.

Polypropylene (PP-R) piping is engineered with heat stabilization and can serve as a tougher, longer- lasting alternative to steel, stainless steel and other plastics for heating, cooling, and industrial applications. POLOPLAST’s hydrophobic, five-layer PP-R piping systems offer higher volumetric flow rates than metal pipes due to thinner walls, and an improvement in thermal expansion compared to non- reinforced plastics. While other piping materials lose performance over time to scaling and corrosion, POLOPLAST pipes resist many forms of change to the pipe wall, and is resistant to impact and seismic stresses.

Corrosion and scaling reduce the inside of steel pipes by an average of 3 percent per year. Design engineers anticipate it in their calculations. This 3 percent per year results in lost efficiency and up to 10 percent increased pumping energy annually. This can add up to thousands of dollars in hidden energy costs over the life of the system. Even after decades of use, PP-R pipe has been found to retain its original flow characteristics. This prevents the loss of efficiency that occurs from scaling and corrosion when using materials such as steel or copper and will save energy over the life of the system.

The non-porous plastic walls of POLOPLAST PP-R pipe experience nearly zero corrosion or scaling throughout their lifespan of more than 40 years. That means they perform as well on the day they are decommissioned for recycling as they did the day they were installed.
