PE has a variety of different drainage pipes. The useful of them is different, but the function is the same - Drain Water. The installation of the drainage pipe is of great significance, because with it, the situation of flooding will not occur. So what types of PE drainage pipes are there? The following we will recommend 4 common PE drainage pipes to you.
At present, there are many varieties of PE drainage pipes, mainly including: HDPE double-wall corrugated pipe, PE hollow-wall winding pipe, HDPE steel belt reinforced polyethylene spiral corrugated pipe and plastic steel winding pipe. Due to different uses, their specifications are also different.

HDPE Steel Belt Reinforced Spiral Corrugated Pipe
It uses U-shaped steel strip composite PE material that greatly increase the ring stiffness of the pipe without increasing the cost. And the strength of the pipe is greatly improved compared with the winding pipe and the carat pipe under the same weight. It can solve a series of problems such as heavy load. The advantages of large-diameter pipes are more obvious. The pipe diameters are from DN300mm to DN2400mm, and the ring stiffness is maintained above 8KN/m2, which is lighter and stronger than cement pipes and other plastic pipes.
Features
- Chemical Resistance: not corroded by pollution, waste water and chemicals, and not corroded by rotten substances in the soil.
- Impact Resistance: The pipe wall adopts a "U"-shaped structure, which is impact resistant and pressure resistant. The foundation will not break even when the foundation is sinking, and it has strong resilience after deformation and has good adaptability to the foundation.
- Anti-aging: The pipe is usually black, which can withstand direct sunlight during storage and construction.
- Cold Resistance: The pipe will not be frozen, cracked, expanded and leaked in an environment of -60°C.
- Light Weight: It's easy to transport and easy to construct. The weight is 1/8 of the weight of the cement pipe. The buried pipe only needs an excavator and does not require large equipment.
- Convenient Connection: The pipes can be connected outside the ditch first, and pushed into the ditch with an excavator, reducing engineering time and costs.
- Superior Abrasion Resistance: It is more abrasion-resistant than steel pipes and cement pipes, and has a stronger capacity to transport domestic water waste slag.
- Superior Drainage Fluidity: smooth inside, reducing friction, and fast drainage.
- Economy: Low construction, management and maintenance costs.
