Wefatherm PP-RCT SDR 7.4 pipes are manufactured from Polypropylene Random Crystallinity Temperature (PP-RCT), a next-generation material offering improved pressure resistance and long-term thermal stability compared to standard PP-R.
These 4-meter green pipes are ideal for:
-
Hot and cold potable water systems
-
Central heating circuits
-
Air-conditioning and chilled water applications
-
High-pressure, high-temperature environments
Standards & Certifications:
-
ISO 15874 — Class 1/10 bar, Class 2/10 bar, Class 4/10 bar, Class 5/8 bar
-
DIN 8077 / 8078 — 20°C / 20 bar, 70°C / 10 bar
PP-RCT ensures optimized flow performance, excellent chemical resistance, and extended service life under elevated temperatures.
