6, low-temperature impact resistance: Low temperature brittleness of polyethylene is very low, can be safely used within a temperature range of -60-60 ℃. Construction in winter, due to material impact resistance, and does not occur tube embrittlement. 7, good resistance to stress cracking resistance: HDPE has a low notch sensitivity, high shear strength and excellent resistance to scratches capacity, resistance to environmental stress cracking resistance is also very prominent. 8, good chemical resistance: HDPE pipe corrosion resistant variety of chemical media, the presence of chemicals in the soil will not cause any degradation of the pipeline. Polyethylene is the electrical insulator, it will not rot, rust or electrochemical corrosion; moreover it will not promote algae, bacteria or fungal growth. 9, good flexibility: Flexible HDPE pipe makes it easy to bend PPR pipe production line, the project can go around obstacles by changing the way the pipeline, on many occasions, the flexible pipe fittings to reduce consumption and lower installation costs. 10, a small flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and non-adhesion properties ensure HDPE pipe has a higher than traditional pipe transmission capacity, but also reduces the pressure loss and water consumption pipeline. After seeing more than ten points, PE pipes are still feeling a lot of advantages, like more PE pipe information, please consult us (1) PE pipe material, non-toxic, non-corrosive, non-scaling, can effectively improve the quality of the pipe network; good capacity of water hammer pressure underground movement and side PE pipe welded joints, load effective resistance, greatly improving the safety and reliability of supply. (2) PE water supply special materials has been greatly developed in recent years, polyethylene materials, is an important reason for the lack of early development, not because of their economies. However, the development of high-performance specialty materials, polyethylene pipe, PE pipe is the advantage of the increasing use of, and expand the application PE pipe. (3) PE pipe has good flexibility and melt it easier to lay the economy and more secure. PE pipe laying speed PPR pipe production line manufacturers, low damage, costs and maintenance costs, as long as the joint can withstand axial load plastic PPR pipe production line, rather than a good leak and release. Therefore, when laying the junction of Crocodiles do not need to spend a small anchor, a firm can reduce costs. PE pipe has unique flexibility PPR pipe production line equipment to more than 500% elongation at break, bend radius pipe diameters up to 20? 25 times, and the ability to fine red marks. Therefore, when laying very easy to move, bend and interludes, for a variety of trenchless pipe, pipe jacking method. Adaptive PE pipes and pipe-based, on the one hand to reduce demand management group, on the other hand, changes in the laying of pipelines is not easily damaged.
