HDPE Co-Extrusion Drainage Pipe is a type of drainage pipe made of high-density polyethylene (HDPE) material, which is characterized by having a double-layer structure and is made by the co-extrusion process. This pipe is usually used in drainage systems for rainwater, sewage, agricultural irrigation, and other drainage tasks.
Application
✅️Highway Drainage: It is used for longitudinal and transverse drainage and water permeability of highways, as well as vertical and horizontal drainage of side ditches at the back of all kinds of soil stall walls.
✅️Municipal engineering: It plays an important role in municipal engineering, such as water purification plants, sewage plants, garbage dump water supply, and drainage systems.
✅️Hillside development: It is used for soil and water conservation of slopes in the development of hillside land, as well as the underground drainage of land preparation projects.
✅️Sports grounds: used for drainage and irrigation in golf courses, sports grounds, parks, and other open green spaces.
Advantage
HDPE Co-Extrusion Drainage Pipe has strong pressure resistance, smooth inner wall, high overflow, easy connection, good sealing of interface, corrosion resistance, Zero leakage, no scaling, etc., can avoid secondary pollution, and is an ideal “green pipe”. In addition, it also has good flexural properties and can adapt to the uneven settlement of soil.
