1) 聚乙烯(PE)管道由于能够承受内压、耐腐蚀性能强，熔接头严密性好等优点，应用前景十分良好。目前在国内已于自来水送用管等优先域使用，保证了输送水质避免二次污染，在燃气管道、化工原料以及工业输油和冷却装置用管优先域亦已被广泛使用。
1, polyethylene (PE) pipeline due to the ability to withstand internal pressure, corrosion resistance, good adhesion and other advantages, the application prospect is very good. At present in the country has been in use in areas such as tap water feeding pipe, to ensure the delivery of water to avoid the two pollution, has been widely used in gas pipelines, chemical raw materials and industrial oil and cooling device for tube field has been.
2) 聚乙烯(PE)管道具有连接可靠，不泄漏、耐化学腐蚀性能好、抗应用开裂性好、低温性冲击性能好、耐老化性好，使用寿命可长达50年，耐磨性能好，可绕性好等优越性能。
2, polyethylene (PE) pipe has reliable connection, no leakage, good resistance to chemical corrosion, anti cracking, application of low temperature impact resistance, good aging resistance, service life of up to 50 years, good wear resistance, good performance can be around.
密封性能好 Good sealing performance：
PE管采用电熔连接、热熔对接、热熔承口、焊制及机械管件连接，接口处强度高于管材本身，不会由于土壤移动或载荷的作用而断裂。PE管在重物直接压过管道，不会导致管道破裂。在使用过程中对于管道基础的适应能力强，在管基发生不均匀沉降和错位时也不容易损坏，同时因为对管基的要求低，可大大节约费用。 The PE pipe welding connection, butt welding, hot melt socket, and mechanical pipe connection, the interface strength is higher than that of the pipe itself, not fracture due to soil movement or load. PE pipe in heavy direct pressure through the pipe will not cause pipeline rupture. In the process of using the pipeline foundation strong ability to adapt, in the base of uneven subsidence and dislocation is not easily damaged, and because of the base requirements low, can greatly save the cost.
