Plastic pipes revolutionize municipal engineering: How do PE double-wall corrugated pipes reshape underground drainage systems?

From the construction perspective, PE double-wall corrugated pipe has significant advantages. It is light, about 1/10 of the weight of traditional reinforced concrete pipes. It does not require large lifting equipment and is easy to carry. The length of a single pipe can reach 6-12 meters. Compared with the general 2-meter-long reinforced concrete pipe, the number of joints is greatly reduced, and the installation is more convenient and faster, which greatly shortens the construction period and reduces the construction cost. Taking the drainage project of a new urban area as an example, after the use of PE double-wall corrugated pipe, the construction time was shortened by nearly one-third, and the comprehensive cost of the project was reduced by about 20%.

In terms of corrosion resistance, PE double-wall corrugated pipe is a leader. Polyethylene has stable chemical properties and can resist corrosion from a variety of chemical media except for a few strong oxidants. It is difficult to be damaged by acidic soil or the complex chemical components in industrial wastewater. This feature not only prevents pipeline leakage due to corrosion and groundwater pollution, but also significantly extends the service life of the pipeline. Under normal underground burial conditions, its service life can reach more than 50 years, far exceeding that of traditional pipes, reducing the waste of manpower and material resources caused by frequent replacement of pipelines.

In addition, PE double-wall corrugated pipe also performs well in environmental protection. The raw materials it uses are green and environmentally friendly, non-toxic and harmless, and can be recycled and reused, which is in line with the current concept of sustainable development. In today's world of ecological protection, it contributes to the green construction of municipal engineering.

In summary, PE double-wall corrugated pipe has reshaped the underground drainage system from multiple dimensions such as improving drainage efficiency, reducing construction costs, extending service life, and enhancing environmental protection performance with its excellent performance. It has become an ideal pipe for the construction and renovation of underground drainage in municipal engineering, leading the new direction of industry development.
