As an important part of ensuring urbanization construction, HDPE pipes for underground water supply are closely related to people’s lives. Therefore, it has extremely high requirements for the safety and reliability of water supply engineering materials. HDPE pipe is a resin material pipe with certain thermoplasticity in material properties. It has high waterproofness, corrosion resistance, and insulation in engineering construction. Good material properties and strong finished product characteristics make HDPE a mature engineering pipeline material used in municipal underground water supply projects.
HDPE is a high-density form of PE. It has the characteristics of heat resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance, and cold resistance. Therefore, it is used in municipal underground water supply and drainage projects.
Performance characteristics of HDPE pipe for underground water supply:
1. Strong pressure resistance. With the surge in urban population and the increase in industrial water use, great pressure is put on urban water supply projects. While ensuring transportation safety, it is necessary to increase water flow, which means that the pressure of the pipeline is bound to increase. The internal structure of HDPE Water Supply Pipe is relatively smooth, its rigidity is strong, and its pressure resistance has been greatly improved, providing a strong guarantee for water supply projects.
2. Strong chemical stability and long service life. Service life is the long-term guarantee of urban water supply projects. Huge projects also mean huge workloads and financial expenditures in maintenance and replacement. Practical experiments have shown that HDPE pipe for underground water supply has good chemical stability. Long-term use will not cause quality problems, nor will it cause erosion to the surrounding environment and soil. The service life of the pipe can be up to 50 years at rated temperature and pressure, which greatly reduces the project cost.
3. Good wear resistance and hydraulic properties, with excellent wear resistance and hydraulic properties, even if it is used underground, it does not require additional outer layer protection and is suitable for various geological conditions, including earthquakes and mining areas.
4. Safe, pollution-free, healthy and environmentally friendly. Water is the source of life. Safety and health are the primary factors in the process of transporting water. HDPE pipe is a non-toxic and odorless pipe that does not harm or pollute the air, human body, etc. It has undergone strict health tests and effectively improved the water quality. In response to the current national and even global requirements for green environmental protection, its own material can be recycled and reused after processing.
The excellent properties of HDPE pipes for underground water supply determine that they can take on important tasks in municipal water supply and drainage projects. With the development of science and technology and the improvement of residents’ living standards, the quality requirements of various industries are getting higher and higher. PE materials have been developed for decades. HDPE is now widely used in various industries. Chinese companies are also making good use of it to develop better products. I believe that the application scope of HDPE will be wider in the future.
