Municipal Sewer Pipe

PE double wall corrugated pipe is a new type of pipe with annular structure outer wall and smooth inner wall. Due to its excellent performance and relatively economic cost, it has been greatly promoted and applied in developed countries such as Europe and the United States.

There are 8 PE double wall corrugated pipe products in total, which are divided into 4 specifications from DN200 to DN500, and are divided into SN2 and Sn4 according to ring stiffness. It is applied to municipal and building rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.

 

 

Annular corrugated structure: it has excellent mechanical properties of both rigid and flexible, high strength, compression resistance, bending resistance and impact resistance.

Smooth inner wall: large water flow, small fluid friction resistance, large flow, no scaling.

Chemical stability: corrosion resistance, non-toxic, pollution-free, outstanding environmental performance.

Hollow frame structure: light weight, convenient construction, greatly reducing construction costs.

Operating temperature range: from -60 ° C to+60 ° C

PE double wall corrugated pipe has certain flexibility and is suitable for areas with uneven soil. The pipe can be directly laid in the groove for bending without pipe fittings.

The service life can reach more than 50 years. The black outer wall has anti ultraviolet and anti-aging properties.

100% recycling, saving resources for the country and protecting the environment.

 

 

If the product doesn't conform to customer's sample or has quality issue, we will make compensation. If the order is large enough, we can give technical guidance and send professional technicians to help solve technical problems. In addition, we also help with design.

 

 

Strength and stiffness: PE double-wall bellows have sufficient mechanical and rigid properties, and both have excellent flexibility, which can withstand the double pressure of soil and power load carrier, and adapt to the uneven settlement of soil.

Leakage prevention and pollution prevention: PE double wall bellows water tightness is excellent, using rubber sealing ring bearing way connection, can ensure that the sewage in the pipe does not leak, and can conform to the uneven settlement of the foundation, will not produce such as rigid concrete pipe disconnection fracture phenomenon, to prevent sewage pollution.

Corrosion resistance and wear resistance: PE double-wall bellows have strong chemical corrosion resistance, can withstand the influence of acid and alkali in the soil, the plastic buried drainage pipe wear resistance is also very good, the buried service life can reach more than 50 years.

Easy for laying and installation: PE double wall corrugated pipe light than concrete pipe, large length, less joint, low for the requirement of trench and foundation, convenient interface connection and good sealing, easy handling, construction, without lifting equipment, artificial installation, low labor intensity, fast speed, can greatly improve the construction efficiency, shorten the construction period.

Good water conservancy characteristics: PE double wall bellows inner wall is smooth, the flow resistance is small, its rough coefficient is only 0.009, and the concrete pipe is 0.013, it can make the water more smooth, improve the water transmission capacity. Under the same use conditions, the water volume of PE double-wall bellows is 30% higher than that of concrete pipes.

Environmental protection and sustainability: PE double-wall bellows are made of high-density polyethylene material, non-toxic and harmless, harmless to the environment, in line with the requirements of sustainable development.

Economic benefits: Although the initial investment of PE double-wall bellows may be higher than that of some traditional pipes, it can finally achieve better economic benefits due to its long-term low maintenance cost and long service life.
