Its maximum operating temperature can reach 95°C, with a long-term operating temperature of 70°C. It exhibits excellent high-temperature resistance and excellent wear resistance, particularly when transporting media such as mineral sand and slurry. It also offers excellent vibration and noise reduction, helping to improve system stability. Even at temperatures as low as -20°C, PP pipe maintains good performance without freezing and cracking. Its low thermal conductivity effectively reduces condensation and heat loss. Made of lightweight materials, PP pipe is easy to install and has a long service life.
