Benefits and Advantages

Intensity and Stiffness

Because plastics embedded pipe is flexible pipe and it endures the press with the soil around in the correct design and construction that plastics embedded pipe doesn’t need the same intensity and stiffness as rigid concrete drainage pipe.

Hydraulic Features

The HDPE double-wall corrugation pipes’ resistance against fluid is much smaller than concrete pipe because of its slippy inner surface. It is proved in practice that smaller diameter plastics pipes can withstand higher flow rate than concrete pipes do at the same slope.

Tightness

The connection of HDPE double-wall corrugation pipe is credible. (Flexible sealing ring bell and socket connection).

Long Lifespan

HDPE double-wall corrugation pipe has many advantages in lifespan and corrosion resistant. Sewage and rainwater transported by embedded pipe is always aggressive, acidity and causticity. Sewage has powerful corrosiveness for example industrial water. HDPE double-wall corrugation pipe has better inoxidizability than metal conduit and concrete pipe. So the HDPE double-wall corrugation pipes’ abrasion resistance is very excellent.

Convenient Installation

Light weight, long length pipe body with less connection parts, low require for pipe ditch and foundation, easy connecting and quick constructing. HDPE double-wall corrugation pipe is very prominent in crowd areas and bad geological areas in the cities.

Economical Cost

The price of HDPE double-wall corrugation pipe is much lower than cast iron pipe. Although it is higher than concrete pipe, the cost of installation is lower and more convenient. Also the lifespan of HDPE double-wall corrugation pipe is much longer than concrete pipe, so the relative cost of HDPE double-wall corrugation pipe is very low.
