Product advantages:

1.  reliable connection: The HDPE double-wall corrugated pipe adopts the advanced socket connection, the strength of the joint is higher than the strength of the pipeline body.

2. Good low temperature impact resistance: the low temperature embrittlement temperature of high-density polyethylene is very low, which can be used safely in the temperature range of -60℃-60℃. Because the HDPE corrugated pipe impact is good, winter construction will not occur brittle crack pipeline.

3. good stress cracking resistance: HDPE double-wall corrugated pipe has low notch sensitivity, high shear strength and excellent scratch resistance, environmental stress cracking resistance is also very prominent.

4. good chemical corrosion resistance: HDPE double-wall bellows can resist the corrosion of a variety of chemical media, the existence of chemicals in the soil capsule will not cause any degradation of the pipeline. HDPE is an insulator, so it will not rot, rust or electrochemical corrosion. It also inhibits the growth of algae, bacteria or fungi.

5. long aging resistance life: containing 2-2, 5% uniform distribution of carbon black HDPE double-wall bellows can be used for more than 50 years.

6. Good wear resistance: the wear resistance comparison test of HDPE double-wall corrugated pipe and steel pipe shows that its wear resistance is 4 times that of steel pipe. This means that HDPE double wall bellows have a longer service life and better economy.

7. good flexibility: the flexibility of HDPE double-wall bellows makes it easy to bend, and the engineering can bypass obstacles by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce the installation cost.

8.  low water resistance: HDPE double-wall bellows have smooth inner surface, its Manning coefficient is 0, 009. The smooth surface and non-stick properties ensure that HDPE double-wall bellows deliver higher transport capacity than traditional pipes, while reducing pipe pressure loss and water consumption.

9. Easy handling: HDPE double-wall corrugated pipe is lighter than condensate pipe, galvanized pipe and steel pipe, it is easy to handle and install, lower manpower and equipment requirements, meaning that the installation cost of the project is greatly reduced.

10. Various construction methods: HDPE double-wall corrugated pipe has a variety of construction technology, in addition to the traditional excavation method can be used for construction, but also can use a variety of new trenchless technology such as pipe jacking, directional drilling, liner, split pipe and other ways of construction, which is the only choice for some places that do not allow excavation, so HDPE double-wall corrugated pipe application field is more extensive.
