Replace the old pipe network in the urban area, and replace the original old sewage pipes with HDPE corrugated pipes

The old sewage pipe network in the urban area has been affected by factors such as sewage corrosion and ground subsidence for a long time, and there are widespread problems such as pipe wall damage, leakage blockage, and low drainage efficiency, which not only easily lead to people's livelihood troubles such as road water accumulation and odor diffusion, but also increase the difficulty of pipe network operation and maintenance. Upgrading is imminent.

In the replacement scheme of old sewage pipes, HDPE corrugated pipes are the best choice because of their strong adaptability. It is made of high-density polyethylene, which has excellent corrosion resistance, can resist long-term erosion of acid and alkali sewage, and delay the aging speed of the pipe wall; the ring stiffness is excellent, which can withstand heavy-load extrusion on the ground, and is suitable for complex underground environments in urban areas; the pipe wall is smooth and smooth, and the fluid resistance is small, which can effectively improve the sewage flow rate and reduce the hidden danger of debris blockage.

Compared with traditional pipes, HDPE corrugated pipes have better flexibility, can adapt to a certain degree of ground subsidence, reduce the risk of pipe network fracture; and are lighter in weight, convenient in construction and handling, can reduce the impact of urban construction on traffic and residents' daily life, and shorten the transformation period. The sealed connection method used is simple and reliable, which can effectively prevent interface leakage and ensure the overall sealing of the pipe network.

The replacement of the HDPE corrugated pipe sewage pipe network can greatly enhance the stability and efficiency of the urban drainage system, reduce the cost of operation and maintenance in the later stage, and lay a solid foundation for urban water environment management, effectively improve the living environment of residents, and help the long-term and stable operation of urban infrastructure.
