3) Advantages of hdpe pipes
connection reliability: polyethylene pipe system connected between the use of electric hotmelt, the joint strength is higher than pipe body strength.
good low temperature impact resistance: low-temperature brittleness of polyethylene low temperature can be within a temperature range of subzero 60 to 60 degrees Celsius safe to use. Construction in winter, because of materials, impact resistance is good, tube embrittlement will not occur.
good stress cracking resistance: HDPE has a low gap sensitivity, high shear strength and excellent anti scratch capabilities, resistance to environmental stress cracking performance is also very prominent.
good resistance to chemical corrosion: HDPE pipe can be resistant to a variety of chemical media, corrosion, chemical substances that exist in the soil will not cause any degradation of the pipeline. Polyethylene is the electrical insulator, it will not happen rot, rust or electrochemical corrosion phenomenon; In addition, it will not promote algae, bacteria or fungal growth.
anti aging, long life: containing 2% to 2.5% of the uniform distribution of carbon black in polyethylene pipe can be outdoor storage or use of 50 years, will not be subjected to ultraviolet radiation damage.
abrasion resistance: HDPE Pipe and comparison tests showed the wear resistance of steel pipe, HDPE pipe 4 times the wear resistance of steel pipe. In the mud transportation field, as compared with the steel pipe, HDPE pipe has better wear resistance, which means that HDPE pipe has a longer life and better economy.
flexible good: HDPE pipe flexible makes it easy to bend, works by changing the pipes can be a way to bypass the obstacles towards, and in many occasions, the flexible pipe fittings to reduce consumption and lower installation costs.
flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. The performance smooth and non adhesion properties ensure the HDPE pipe has a higher than traditional pipe transmission capacity, but also reduce the pipeline pressure loss and water consumption.
handling easily: HDPE pipe than concrete pipes, galvanized pipe and steel pipe lighter, it is easy handling and installation, lower manpower and equipment needs, which means the project installation costs of the greatly reduced.
