Double Wall Corrugated Pipes
Double wall corrugated pipes are a new type of drain pipe. In virtue of perfect design concept and unique hollow structure, they realize quite even force on pipe wall.
Applications of the Corrugated Pipes
1. Subdrainage, sewage drainage and rain collection systems in municipal construction;
2. Irrigation and drainage for farmlands, fruit gardens, tea gardens and woodlands;
3. Flood discharge system in water conservancy projects;
4. Wastewater discharge in chemical, pharmaceutical and other industries;
5. Water french drain pipes in airports, golf courses and other places;
6. Vent and drain pipes in mines and buildings;
7. Embedded pipes and water seepage drainage pipes for railways and highways
Advantages:
1. Choose Top Quality Raw Materials
Control density and MI—to ensure the mechanical property and machinability of raw materials
Control elongation at break—to ensure product toughness and improve circular flexibility
Control elasticity modulus and tensile strength—to ensure circular rigidity of pipes
Control OIT—to ensure the weather resistance of pipes
2. Introduce Advanced Horizontal Extruder
The extruder that we use for making double wall corrugated pipes comes with uniform load. Each module can run stably at a constant speed, thus ensuring dimensional stability.
