PE pipe for water supply is the traditional steel pipe, PVC water pipe replacement. Water supply must withstand a certain pressure, usually opt for large molecular weight, good mechanical properties of PE resins, such as HDPE resins. LDPE resin is low tensile strength, pressure difference, poor rigidity, poor dimensional stability during molding, and the connection difficulties, suitable as water pressure tube material. However, because of its high health indicators, PE especially HDPE resin production of drinking water has become a common pipe materials. HDPE resin melt viscosity is small, good fluidity, easy processing, and therefore their choice is also a wide range of melt index of PE pipe production line, usually between MI 0.3-3g / 10min. (1) PE pipe material, non-toxic, non-corrosive, non-scale manufacturer of PE pipe production line, which can effectively improve the quality of the pipe network; good capacity of water hammer pressure underground movement PE pipe welded joints and side loading effective resistance, greatly improving the safety and reliability of supply. (2) PE water supply special materials has been greatly developed in recent years, polyethylene material customized PE pipe production line, 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 supply PE pipe production line, expand the application of PE pipe. (3) PE pipe has good flexibility and melt it easier to lay the economy and more secure. PE pipe laying rate, damage, cost and low maintenance costs, as long as the joint can withstand axial load, 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 a unique flexibility 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.
