PE drainage pipe link method
现如今 PE排水管的使用已经是城市施工建设的潮流，那么了解PE排水管的连接方式对未来的工作便大有益处 Urban water pipes are like the blood vessels of a city. Good drainage pipes provide peace of mind. Nowadays , the use of PE drainage pipes is already a trend in urban construction. So understanding the connection methods of PE drainage pipes will be of great benefit to future work.
最常见的连接方式有：热熔连接，电熔连接，承插式柔性连接 和 法兰连接，钢塑过渡接头连接等。 The most common connection methods for PE drainage pipes are: hot-melt connection, electric fusion connection, socket-type flexible connection and flange connection, steel-plastic transition joint connection, etc.
PE排水管材 或管件的待连接部位，使其熔融后，移走加热工具，施压将两个熔融面连在一起，在稳定的压力下保持一段时间，直到接头冷却。 Hot-melt connection is a special heating tool. Under pressure, heat the PE drainage pipe or pipe to be connected. After it is melted, remove the heating tool and apply pressure to connect the two molten surfaces together. Maintain a section under stable pressure. Time until the joint cools. Hot-melt connections include hot-melt butt connections, hot-melt socket connections, and hot-melt saddle connections.
PE排水管材 的连接部位紧密接触通电，通过内埋的电阻丝加热连接部位，使其融为一体，直至接头冷却。 The electric fuse connection uses a special electric fuse with a built-in resistance wire in close contact with the connection part of the PE drainage pipe to energize, and the connection part is heated by the embedded resistance wire to fuse it together until the joint is cooled. PE排水管材 或插口管件连接。 Electrofusion connection can be used to connect PE drainage pipes or socket fittings of different types and different melt flow rates . Electrofusion connection is divided into fused socket connection and fused saddle connection.
管道承插式柔性连接是参照铸铁和聚氯乙烯管 (pvc-u)的承插式柔性连接的原理开发的一种新型连接方式. 它是在 PE排水管材 一端焊接一个经过加固的 PE 承口。 PE pipe socket type flexible connection is a new type of connection method developed based on the principle of socket type flexible connection of cast iron and polyvinyl chloride (PVC-U) pipe . It is a reinforced PE welded on one end of PE drainage pipe Slot.
PE排水管材 一端直接插入 PE排水管材 或管件特制的的承口中，通过承口中内的锁紧环压紧抗拉拔，橡胶密封圈压紧密封，达到连接 PE排水管材 和管件的目的。 Socket-type flexible connection is to insert one end of PE drainage pipe directly into the special socket of PE drainage pipe or pipe fittings, and the compression ring is pressed against the pull-out by the locking ring in the socket. And fittings purpose.
PE 管道与金属管道或者阀门，流量计，压力表等附属设备的连接。 The flange connection is mainly used to connect PE pipes with metal pipes or auxiliary equipment such as valves, flow meters, pressure gauges. PE 法兰连接件，钢制或是铝制法兰片，垫片或密封圈、螺栓、螺母等组成。 The flange connection is mainly composed of PE flange connectors, steel or aluminum flanges, gaskets or seals, bolts, nuts, etc. The flange connection is to achieve the connection purpose by tightening the bolts and nuts to make the flange connection piece and the flange piece tightly contact.
PE 管道和金属管道。 The steel-plastic transition joint connection uses a steel-plastic transition joint prefabricated by cold pressing or other methods to connect PE pipes and metal pipes. PE 管道。 Steel-plastic transition joints have pull-resistant locking rings and seals, which usually require good sealing performance, resistance to pull-out and pressure resistance to be greater than PE pipes in the system .
Of course, the choice of specific processing operation methods must be determined according to the requirements of each region and industry.
