Double-wall plastic corrugated pipe is made of "HDPE (high-density polyethylene) corrugated pipe", "PVC-U (hard polyvinyl chloride) corrugated pipe", "PP (polypropylene) corrugated pipe", etc. as the main raw materials. , The external extruder co-extrudes, one-time molding, the inner wall is smooth, the outer wall is corrugated, and there is a hollow layer of plastic pipe between the inner and outer walls. The pipe is suitable for a large temperature range (+60ºC- -20ºC). Because of its unique structure, the product has high ring stiffness, high strength, light weight, sound insulation and shock absorption, UV resistance, long service life, pressure resistance, and It has many advantages such as high impact strength, strong corrosion resistance, cold and heat resistance. HDPE perforated corrugated pipe, soft permeable pipe, and plastic blind ditch have become the three main products in civil engineering construction in my country.

Features:
1. The pipeline material with strong corrosion resistance is PE, which will not be corroded by acid, alkali and oil.
2. The pipeline with strong resistance to external forces has the shape of spiral structure and flexibility. When it is subjected to external impact, it has strong resilience.
3, strong aging resistance pipeline substrate characteristics at 20 degrees can be effectively used for more than 50 years, has a strong aging resistance.
4, strong cold resistance in the environment of minus 60 degrees, pipe will not be frozen broken water.
5. The light weight is only 1/8 of the concrete pipe of the same specification and 2/3 of the traditional wound plastic structural pipe, which is convenient for transportation and construction and does not require large construction equipment, thus reducing the installation cost.
6. Low construction cost, light weight, convenient connection, and low requirements for excavation projects. It can save project time and costs in urban drainage project construction.
7, easy to connect the connection of various ways, simple, reliable.The site can be easily constructed.
8, superior abrasion resistance pipeline friction coefficient low, small resistance, transmission medium, drainage, sewage speed.
9, good environmental performance Pe itself is non-toxic renewable material, environmental health.
10. High ring stiffness can reach SN12.5 and SN16
 

Application Field

1. Drainage and ventilation pipes for mines and buildings;
2. Municipal engineering, underground drainage and sewage pipelines in residential quarters;
3. Irrigation and drainage of farmland water conservancy; drainage pipes for sewage treatment plants and garbage disposal sites;
4. Chemical ventilation pipes and chemical and mining fluid conveying pipes;
5. The overall processing of pipeline inspection wells; high-speed kilometers of pre-buried pipelines;
6, high-voltage cables, post and telecommunications cable protection sleeves, etc.
