※ Product Introduction
HDPE double wall corrugated pipe is mainly made of high-density polyethylene (HDPE), with necessary additives added, and extruded into shape. It has a structure with a smooth inner wall and a corrugated outer wall, and a hollow and tightly welded annular structure between the inner and outer walls, hence the name double wall corrugated pipe.
※ Product Features
1High strength and good impact resistance The outer wall of the circular ripple is endowed with high ring stiffness, strong resistance to soil load and external pressure, and impact resistance, making it less prone to deformation and damage.
2Good resistance to uneven settlement performance Flexible pipes have flexibility, can adapt to soil settlement, have low requirements for foundation treatment, and are suitable for complex foundations such as soft soil and quicksand.
3Convenient connection and good sealing performanceAdopting socket type (rubber ring sealing) or hot melt connection, the operation is simple, the joint has no leakage, and the sealing is reliable.
4Smooth inner wall and strong water flow capacitySmooth inner wall with low friction, larger flow rate for the same diameter, or smaller diameter can be used for the same flow rate to reduce project costs.
5. Corrosion resistant and wear-resistant HDPE material has good chemical stability, acid and alkali resistance, and wear resistance better than steel pipes and cement pipes, with a long service life. Lightweight and easy to construct: With low density and light weight, it is easy to install and reduces construction costs.
6. Good environmental performancePolyethylene is non-toxic and renewable, does not pollute the environment, does not breed bacteria, does not scale, and has stable flow.
※ Implementation standards
