Plum porous HDPE pipe has a strong compatibility and use, it is suitable for communication cable, telecommunication cable network, long-distance communication lines and cable television broadcasting transmission network, widely used in telecommunications, broadcasting, railways, military units, institutions, large and medium use of internal communications, industrial and mining enterprises. Plum is the development and production of cement pipe block replacement products, on multiple cable identification, improve efficiency, perforated pipe will be replaced, seven holes Plum and corrugated tubes, tube group, will be the development of urban communication channels prospects and an inevitable trend. Raw materials used for PE (polyethylene) as the main base material, suitable for wide temperature range (+80 ℃ - -40 ℃), low temperature resilience, resistance, impact resistance, and acid resistant, anti-aging . Cold in the tropics can be used. Corrosion resistance, electrical insulation.
