PE可用很宽的不同加工法制造。PE给水管以乙烯为主要原料，丙烯、1-丁烯、己烯为共聚体，在催化剂的作用下，采用淤浆聚合或气相聚合工艺，所得到的聚合物经闪蒸、分离、干燥、造粒等工序，获得颗粒均匀的成品。包括诸如片材挤塑、薄膜挤出、管材或型材挤塑，吹塑、注塑和滚塑。

PE can be manufactured in a wide range of different processing methods. The PE water supply pipe uses ethylene as the main raw material, propylene, 1-butene, and hexene as copolymers. Under the action of a catalyst, a slurry polymerization or gas phase polymerization process is adopted. The obtained polymer is flashed, separated, dried, Processes such as granulation to obtain finished products with uniform particles. Including such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotational molding.

　　我国塑料管道发展很快，质量在不断提高。目前，已初步形成以聚氯乙烯（PVC-U）管、聚乙烯（PE）管和聚丙烯（PP-R）管为主的塑料管产业。其中聚乙烯（PE）管由于其自身独特的优点被广泛的应用于建筑给水，建筑排水，埋地排水管，建筑采暖、输气管，电工与电讯保护套管、工业用管、农业用管等。其主要应用于城市供水、城市燃气供应及农田灌溉。

　　 my country's plastic pipes are developing rapidly, and their quality is constantly improving. At present, a plastic pipe industry with polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes and polypropylene (PP-R) pipes as the mainstay has initially formed. Among them, polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission pipes, electrical and telecommunications protection sleeves, industrial pipes, agricultural pipes, etc. due to their unique advantages. . It is mainly used in urban water supply, urban gas supply and farmland irrigation.

PE管加工时不添加重金属盐稳定剂，材质无毒性，无结垢层，不滋生细菌，很好地解决了城市饮用水的二次污染。在额定温度、压力状况下，PE管道可安全使用50年以上。PE管韧性好，耐冲击强度高，重物直接压过管道，不会导致管道破裂。PE具有优良的耐大多数生活和工业用化学品的特性。

When PE pipe is processed, no heavy metal salt stabilizer is added, the material is non-toxic, no scaling layer, no bacteria breeding, and it solves the secondary pollution of urban drinking water. Under rated temperature and pressure conditions, PE pipes can be used safely for more than 50 years. The PE pipe has good toughness and high impact resistance, and the heavy objects are directly pressed through the pipe, which will not cause the pipe to rupture. PE has excellent resistance to most domestic and industrial chemicals.
