HDPE pipe

High-density polyethylene (HDPE) has excellent chemical stability, anti-aging and resistance to environmental stress cracking performance. Applicable to a wide temperature range, pressure-bearing ability, and has good comprehensive mechanical properties. Features: 1. Chemical stability. As the HDPE molecule is not polar, so a good chemical stability. At a small number of oxidants, most can not afford to undermine its role in chemical media. Does not breed bacteria do not scale, its circulation area would not be with the running time increases. Are environmentally friendly products. 2. Connection strength good (mainly Butt Socket) such as: small joints, no leaks. 3. The construction and convenient. As the HDPE pipe, light weight, handling and connection is very convenient, it works fast and easy maintenance. Tight schedule and construction in poor circumstances, its advantages become more pronounced. 4. Wear resistance coefficient is small, flows. HDPE pipes used for materials other than the same diameter pipe can be a greater flow. In other words, the same request, can be used a relatively small diameter HDPE pipe. 5. Have a certain flexibility and a good deflection degrees (22.50). HDPE pipe can be a slight axial deflection, free from the ground to some extent the impact of uneven settlement; can not pipe directly at the little shop inside the grooves are not straight and so on. 6. A good low temperature resistance, impact resistance of the brittle temperature (-70 ° C), the general low-temperature conditions (-30 ° C or less) do not have to be taken during the construction of special protection measures to facilitate construction in winter. In addition, polyethylene pipe has a good impact resistance, even with 2.5 times the nominal pressure of water hammer it will not cause any damage to pipelines. 7. Excellent wear resistance. Germany has the wear resistance of HDPE with the results show even higher than even the brass several times. 8. Compressive ability. Compared with the other pipe has obvious advantages. 9. Long service life. Ultraviolet light without direct sun under the conditions of life of up to 50 years
