Concrete and reinforced concrete pipes have the unique advantages of high compressive strength, good durability, long service life, easy manufacture, low production cost and low price. They are widely used for laying drainage in urban construction, industrial and mining enterprise construction, and farmland water conservancy construction. The pipeline has achieved good economic and social benefits.
HDPE Double-Wall Corrugated Pipe
The concrete pipe has a relatively slow water flow velocity, a large resistance, and a relatively weak corrosion resistance.
Plastic pipe applications are relatively large under smaller pipe diameters. Through economic comparison, the use of plastic pipes under smaller pipe diameter conditions is more reasonable; under larger pipe diameter conditions, coagulation
The soil pipe is more reasonable.
With the continuous development of urbanization, the demand for large-diameter rainwater pipes and drain pipes is increasing. The production cost of concrete pipes is low, the durability is good, and the compressive strength is high. It is suitable for the development of the market. Therefore, the large-diameter drainage pipes will be concrete pipes in the future. Main tube
material. In order to overcome the shortcomings of resistance and corrosion resistance, PVC lining should be widely used in large-diameter concrete pipes.

Trend analysis of municipal water supply and drainage pipes
Future urban water supply and drainage pipe application trends will present the following characteristics:
1High durability direction
The municipal water supply and drainage pipe used in China is not long, and the verification of its design life is concerned.
There is still no data, but in terms of corrosion resistance, plastic pipes are superior to metal pipes, so plastic pipes are used more in municipal water supply and drainage pipes than metal pipes.

2Flexible interface type is more widely used。
The future development trend of municipal water supply and drainage pipes is to use flexible combined interface water supply.
Drainage pipe, convenient installation of pipeline, low probability of water leakage。
3Large-caliber, multi-variety development trend。
Large-diameter drain pipes are more likely to be used for reinforced concrete, and sand pipes are also larger.
Possibly, but it is limited in areas with low winter temperatures. The “Twelfth Five-Year Plan” has clearly indicated that industrial waste can be used in concrete, so it can be used in large-diameter reinforced concrete.
