PE corrugated drainage pipe with diameter of 110-600mm is delivered from Datong manufacturer's stock

  Main advantages of HDPE Double wall bellows:
  (1) : sufficient strength and rigidity
HDPE Double wall corrugated pipe is a kind of buried drainage and sewage pipe, which belongs to flexible pipe
Its characteristics are both rigid and flexible, that is, it has sufficient mechanical properties and rigid properties, as well as excellent flexibility
The load bearing mechanism of flexible pipe is completely different from that of rigid pipe
Flexible pipe can have large deformation before failure, but rigid pipe cannot
Under the same external pressure load, the stress in the flexible pipe wall is small
It bears the load together with the surrounding backfill, and the pipe soil acts together
Therefore, the double wall bellows does not need the same strength and stiffness as the rigid concrete
Under the reasonable stiffness, it can fully meet the service requirements, which has been realized by the application practice of some developed countries
Compared with cement pipe, double wall corrugated pipe not only has light weight, but also has great compressive strength, good impact resistance and bending resistance
It can bear the dual pressure of soil and dynamic load carrier, and can adapt to the uneven settlement of soil

(2): it has good water conservancy characteristics
HDPE Double wall corrugated pipe has smooth inner wall and small flow resistance, and its roughness coefficient is only 0
009, while that of concrete pipe is 0
013,
It can make the water smoother and improve the water delivery capacity
Under the same service conditions, the water delivery capacity of double wall corrugated pipe is 30% higher than that of concrete pipe
Practice shows that under the same slope, the PE double wall bellows with smaller diameter can achieve the required flow, avoid the accumulation and stagnation of waste, and avoid the worry of pipeline dredging in the future

(3): no leakage and prevention of environmental pollution
HDPE Double wall corrugated pipe has excellent water tightness
Due to the socket connection of rubber sealing ring, it can ensure that the sewage in the storage does not leak, comply with the uneven settlement of the foundation, and will not produce disconnection and fracture such as rigid concrete pipe, so as to prevent sewage pollution

(4): long service life, corrosion resistance and wear resistance
Double wall corrugated pipe has strong chemical corrosion resistance and can withstand the influence of acid and alkali in soil
The wear resistance of plastic buried drainage pipe is also very good
The buried service life can reach more than 50 years

(5): convenient for laying and installation
HDPE Double wall corrugated pipe is lighter than concrete pipe, with large length, less joints, low requirements for pipe trench and foundation, convenient interface connection and good sealing
Easy to handle, simple and convenient construction, and manual installation without hoisting equipment
The construction labor intensity is low and the speed is fast, which can greatly improve the construction efficiency and shorten the construction period
In crowded or poor geological areas (such as high groundwater level and soft foundation), geotechnical double wall bellows has greater advantages
