Urban projects use PE pipes to achieve a win-win situation in drainage efficiency and ecological benefits

Take Heze City as an example. Its old urban drainage network was built in the 20th century. The HDPE corrugated pipes used have many problems such as deformation, collapse, and rupture over time, and urban waterlogging has occurred frequently. In this renovation project, some areas have selected PE pipes with better performance. The inner wall of the PE pipe is extremely smooth, the friction coefficient is extremely low, and the resistance when water flows through is small, which can greatly increase the flow rate of sewage and rainwater. This means that in extreme weather such as heavy rain, the city can remove the accumulated water more quickly, effectively reduce the pressure of waterlogging, and protect the lives and property of residents. Compared with traditional pipes, the drainage efficiency of PE pipes can be increased by about 30% - 40%, greatly enhancing the city's ability to cope with sudden rainfall.

From the perspective of ecological benefits, PE pipes have significant advantages. It is made of high-density polyethylene material, has strong chemical stability and excellent corrosion resistance. Whether it is facing industrial sewage containing acid and alkali substances or being in a corrosive soil environment for a long time, it can remain stable and not easily eroded and damaged. This feature not only extends the service life of the pipe, reduces the waste of resources and environmental pollution caused by frequent pipe replacement, but also reduces the long-term operating cost of the urban drainage system. It is estimated that after using PE pipes, the frequency of pipe replacement can be reduced by about 50% - 60%, and the maintenance cost is also greatly reduced.

At the same time, PE pipes are green and environmentally friendly, the materials are non-toxic and harmless, and can be recycled and reused. During the production process, its energy consumption is relatively low and the impact on the environment is minimal. At present, advocating green development, this feature is highly consistent with the concept of sustainable development in cities. Moreover, PE pipes are light in weight and flexible. When installed, convenient methods such as hot-melt butt welding can be used. The construction process is simple and fast, which can effectively shorten the construction period. This not only reduces the interference of construction on urban traffic and residents' lives, but also indirectly reduces energy consumption and carbon emissions during construction.

In the water supply network renovation project in Heze City, after replacing the old galvanized pipes with PE pipes, residents clearly felt that the water pressure was more stable and the water quality was clearer. In a Jinan community, replacing over 30-year-old cement pipes with PE pipes resolved issues such as insufficient water pressure and compromised water quality. These success stories fully demonstrate that PE pipes not only improve urban drainage efficiency but also contribute to the protection and improvement of the ecological environment, laying a solid foundation for high-quality urban development.

From alleviating flooding in Heze City to improving water quality in Jinan communities, the outstanding performance of PE pipes in urban drainage and water supply system renovations not only reflects the advancement of materials technology but also the underlying principle that "details determine effectiveness" in urban construction.

This pipe, combining high drainage efficiency, strong corrosion resistance, and low environmental impact, redefines the value of infrastructure upgrades with its tangible performance advantages. It not only reduces flooding on streets during heavy rains and ensures cleaner water flows from residents' taps, but also reduces the burden on sustainable urban development with its longer service life and lower maintenance costs.

In the future, as more cities pursue both ecology and efficiency, practical and environmentally friendly materials such as PE pipes will play a more important role in infrastructure renewal, continuously injecting momentum into the city's "smooth blood circulation" and "healthy growth", making every pipeline network renovation a solid step towards improving residents' sense of happiness.
