The higher-performance pipe material class PP-RCT has been valued by the plastic piping industry for its superior performance for the past decade. Now the superior qualities of this class have been officially confirmed thanks to its inclusion in the most recent publication of EN ISO 15874, the global standard for plastics piping systems for hot and cold water pipe installations. This international standard will accelerate the adoption of this second-generation PP-R-material class along the entire pipe value chain.
Borealis led the way with its launch of this material class back in 2004. It's PP-RCT classified materials which are ready compounded for maximum quality control and available in green (Borealis RA7050-GN) and steel grey (Borealis RA7050), are produced using a special multiple-reactor technology. They contain a high level of beta-nucleated crystals and a state-of-the-art stabilisation package. These features allow for operation at higher stresses at elevated temperatures, opening up a wide spectrum of applications including large diameter pipes for skyscrapers. "Designers and installers are increasingly seeing the vast benefits achievable with PP-RCT pipes," adds Anton Wolfsberger, Borealis Marketing Manager Energy & Infrastructure. "Our Borealis RA7050 materials are, with nearly a ten year track record, well-established on the market as reliable, high quality PP-RCT pipe materials."
For example, PP-RCT makes an increase in hydraulic capacity possible while maintaining outer pipe diameter. A higher percentage of smaller pipes may be installed with no reduction in overall water supply. Using the dimension of standard PP-R pipes with higher operating pressures even opens up entirely new areas of use.
