HDPE PIPE APPLICATION
Water supply and drainage project of the municipal government, as an important part of ensuring urbanization, is closely related to people's lives, so it has extremely high requirements for the safety and reliability of water supply and drainage engineering materials. HDPE pipe is a kind of resin material pipe, which has thermoplasticity, and reflects high waterproofness, corrosion resistance and insulation in engineering construction. Good material properties make HDPE already a mature engineering pipe material used in municipal water supply projects.
HDPE is a high-density form of PE, which has the characteristics of temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance.In addition, it has good electrical insulation, impact resistance and cold resistance, so it is well used in municipalwater supply and drainage projects.
HEPE performance characteristics:
1. Strong pressure resistance. With the rapid increase in urban population and the increase in industrial water use, urban water supply projects are under great pressure. While ensuring transportation safety, water flow needs to be increased, which means that the pressure on the pipeline is bound to increase. The internal structure of the HDPE water supply pipe is relatively smooth, and the outside is annular corrugated. Its rigidity is strong, and its compression resistance has been greatly improved, providing a strong guarantee for the water supply project.
2. Strong chemical stability and long service life. The service life is a long-term guarantee for urban water supply projects. The maintenance and replacement of vast projects also means huge workload and financial expenditure. Practical experiments have shown that HDPE pipes have good chemical stability and will not cause quality problems for a long time, nor will they cause erosion to the surrounding environment and soil. Under the rated temperature and pressure, the service life of the pipe can be as long as 50 years, which greatly reduces the engineering cost.
3. Good flexibility and anti-scratch ability. Small-diameter high-density polyethylene pipes can be rolled into discs, which have good plasticity in transportation and construction, reducing the difficulty of construction. It has a good anti-scratch ability, which is 4 times that of the same steel pipe, and has good wear resistance. It is suitable for all types of trenchless engineering.
4. Safe and 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 and the human body. After strict health tests, the water quality is effectively improved. Corresponding to the current national and global requirements for environmental protection, its own materials can be recycled and reused.
The excellent self-properties determine that HDPE pipes can be shouldered in municipal water supply and drainage projects. With the development of technology and the improvement of residents’ living standards, the quality requirements of various industries are becoming higher and higher. PE materials have been developed for decades. HDPE is now widely used in all walks of life, and Chinese companies are also making good use of researching and developing better products, believing HDPE will have a wider range of applications in the future.
