HDPE pipeline system advantages:
1, the connection is reliable: the polyethylene pipe system is connected by the electric heating melting mode, and the strength of the joint is higher than the strength of the pipe body.
2, good impact resistance at low temperature: low temperature brittleness temperature of polyethylene is very low, it can be safely used in the range of -60-60 C. During the winter construction, because of the good impact resistance of the material, the pipe brittle fracture will not occur.
3, good resistance to stress cracking. HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and is also very outstanding in environmental stress cracking.
4, good chemical corrosion resistance: HDPE pipe corrosion resistant variety of chemical medium, the presence of soil chemical substances will not cause any degradation of pipeline. Polyethylene is an electrical insulator, so there is no decay, rust or electrochemical corrosion, and it will not promote the growth of algae, bacteria, or fungi.
5, aging resistance and long service life: polyethylene pipes with evenly distributed carbon black containing 2-2.5% can be stored in outdoor open air for 50 years, and will not be damaged by ultraviolet radiation.
6, good wear resistance: the comparison test of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times of that of steel pipe. In the field of slurry transportation, compared with steel pipe, HDPE pipe has better wear resistance, which means that HDPE pipeline has longer service life and better economy.
7, flexibility is good: HDPE pipeline flexibility makes it easy to bend, engineering can change the way of pipeline to bypass obstacles. In many cases, pipeline flexibility can reduce pipe consumption and reduce installation costs.
8, the flow resistance is small: the HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. Smooth performance and non adherence characteristics ensure that HDPE pipeline has higher transport capacity than traditional pipes, and also reduces pipeline pressure loss and water consumption.
9, easy handling: HDPE pipeline is lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to handle and install, and lower manpower and equipment needs, which means that the installation cost of engineering is greatly reduced.
10, a variety of new construction methods: HDPE pipe has a variety of construction technology, in addition to using the traditional excavation method of construction, also can use technologies such as trenchless pipe jacking, directional drilling, pipe liner, etc. a variety of new construction, the excavation is not allowed in some places, is the only choice the application field of HDPE channel is more widely.
