HDPE pipe, also known as high density polyethylene pipe, is a single-layer solid wall pipe. Compared with the traditional steel pipe and concrete pipe, it has many advantages, such as strong corrosion resistance, light weight, good sanitary performance, good low temperature impact resistance, etc., at the same time, it can reduce the engineering cost and shorten the construction period.
Good sanitary performance: HDPE pipe does not add heavy metal salt stabilizer, the material is non-toxic, no scaling layer, no bacteria breeding, which can better solve the secondary pollution of urban drinking water. Comply with GB / t17219 safety performance evaluation standard and relevant health and safety evaluation regulations of the Ministry of health of the people's Republic of China;
Good chemical corrosion resistance: HDPE pipeline can resist the corrosion of various chemical media, and the chemical substances in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi;
The joint strength is higher than that of the pipe body;
Convenient handling: HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe, and it is easy to handle and install. Lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced;
Long service life: HDPE material has long-term heat resistance stability. According to the international iso9080 test, the service life of extrapolated pipeline under normal service pressure of 20 ℃ is more than 50 years;
