PVC-U Double Wall Corrugated Pipe is a special pipe material with smooth inner wall, corrugated outer wall, and hollow inner and outer walls, which is mainly made of polyvinyl chloride. The pipe has a beautiful appearance, strong pressure resistance, low water resistance, and resistance to acid and alkali corrosion. It is easy to install and transport, and has significant advantages of energy saving, material saving, and water saving.
Features:
1. Unique structure, high strength, strong compressive performance;
2. Smooth inner wall, low friction resistance, large flow rate;
3. Corrosion resistance, leak resistance, good environmental protection effect;
4. Convenient connection, good sealing performance, strong resistance to uneven settlement;
5. The service life when buried reaches more than fifty years.
Application:
Telecommunication engineering, construction engineering, sewage pipeline engineering, brine engineering, tunnelling engineering, chemical factories, paper mills, farmland irrigation engineering, highway engineering, aquaculture, sewage treatment engineering.
Unique structure, high strength, smooth inner wall, low friction resistance, large flow rate, no need for concrete foundation, light weight, easy to handle and install, quick construction; rubber ring joint, reliable method, easy to ensure construction quality; flexible interface. Strong resistance to uneven settlement; good leak resistance, can withstand erosion of various chemical media; no scaling inside the pipe, basically no need for dredging, buried service life reaches more than fifty years.
