HDPE double wall corrugated drainage pipe is a new type of lightweight pipe made of polyethylene as raw material, which is processed by extrusion and special molding process. The inner wall is smooth and the outer wall is closed corrugated. HDPE Double Wall Corrugated Drainage Pipe takes below technology : Digital centralized control; Double material extruding together and double layer separation; All vacuum belt feeding; Random expanding one-time molding.
Features:
1. Excellent physical and chemical properties:
high impact strength, good pressure resistance , long service life (according to the national Ministry of Construction test data that the use of years 40-50)
2. Light weight:
easy installation, the use of line and socket. Weight only one-seventh of the same diameter cast iron pipe, can greatly speed up the progress of the project and reduce construction costs.
3. Small fluid resistance:
smooth inner wall, the rough coefficient of only 0.009, so the fluid resistance is small, compared with the same diameter cast iron pipe flow increased by 30%.
4. Anti-aging:
the use of special compound design, no aging discoloration of the worry.
5. Pest control:
the use of a unique auxiliary agent, so that the product will not issue psoriasis like the smell, to avoid termites, insects gnawing damage.
6. Non-toxic:
not contain toxic lead salt and other toxic chemicals.
