pe给水管的5种链接方式!

  PE水管连接方式:
  PE water pipe connection mode:
  连接聚乙烯管和聚乙烯管、聚乙烯管和聚乙烯管、聚乙烯管和管件、聚乙烯管和金属管的方法有很多。不同的连接方式各有优缺点。用户可根据管径、工作压力、使用场所等环境选择合适的连接方式。城市供水聚乙烯管道最常用的连接方式有:热熔连接、电熔连接、插座式柔性连接、法兰连接、钢塑过渡接头连接等。
  There are many ways to connect polyethylene pipe and polyethylene pipe, polyethylene pipe and polyethylene pipe, polyethylene pipe and fittings, polyethylene pipe and metal pipe. Different connection modes have their own advantages and disadvantages. Users can choose the appropriate connection mode according to the pipe diameter, working pressure, place of use and other environments. The most common connection modes of urban water supply polyethylene pipeline are hot melt connection, electric melt connection, socket flexible connection, flange connection, steel-plastic transition joint connection, etc.
  1. 热熔连接
  1. Hot melt connection
  热熔连接是用专用的加热工具,在压力下加热聚乙烯管或管件要连接的部件,使其熔化,取出加热工具,压力将两个熔化面压在一起,在稳定的压力下保持一段时间,直至接头冷却。热熔连接包括热熔对接连接、热熔插座连接和热熔鞍座连接。[1]
  Hot melt connection is a special heating tool, which heates the parts of polyethylene pipe or fittings to be connected under pressure to melt and take out the heating tool. Pressure will press the two melting surfaces together and keep them under stable pressure for a period of time until the joint is cooled. Hot-melt connection includes hot-melt butt connection, hot-melt socket connection and hot-melt saddle connection. [1]
  2. 电融合连接
  2. Electrical Fusion Connection
  电熔接是一种特殊的电熔管,它与预埋电阻丝或PE管或连接管件的部分紧密接触并通电。PE管通过预埋电阻丝加热连接件,使连接件熔化并整体连接,直至连接处冷却。电熔接头可用于连接不同类型和熔体流量的聚乙烯管道或插座配件。有电焊插座连接和电焊鞍座连接。
  Fusion welding is a special kind of fused pipe, which contacts and electrifies the embedded resistance wire or PE pipe or the part connecting the pipe. PE pipes are heated by embedded resistance wires to melt the connectors and connect them as a whole until they are cooled at the junction. Fused joints can be used to connect polyethylene pipes or socket fittings of different types and melt flow rates. There are electric welding socket connection and electric welding saddle connection.
  3.插座与插座式灵活连接
  3. Flexible connection between socket and socket
  PE管承插柔性连接是借鉴铸铁管与PVC管(PVC -u)承插柔性连接原理而发展起来的一种新型连接方法。聚乙烯管在聚乙烯管的一端焊接有加强聚乙烯插座。插座与插座式柔性连接是将聚乙烯管的一端直接插入管道或管件的专用口内。通过口内的锁紧环,可压紧耐拉紧,并与橡胶密封圈紧密密封,连接PE管与管件。

  PE pipe socket flexible connection is a new connection method based on the principle of socket flexible connection between cast iron pipe and PVC-u pipe. The polyethylene pipe is welded at one end of the polyethylene pipe with a reinforced polyethylene socket. The flexible connection between socket and socket is to insert one end of the polyethylene pipe directly into the special opening of the pipe or fittings. Through the locking ring in the mouth, it can tighten and withstand tension, and is tightly sealed with rubber sealing ring, connecting PE pipe and fittings.
  4,法兰连接
  4. Flange connection
  法兰连接主要用于聚乙烯管与金属管或阀门、流量计、压力表等辅助设备的连接。法兰连接主要由聚乙烯法兰、钢或铝背压套法兰、钢或铝法兰片、垫片或密封圈、螺栓、螺母等部件组成。法兰连接是通过紧固螺栓、螺母,使法兰接头与法兰片紧密接触,达到连接的目的。
  Flange connection is mainly used to connect polyethylene pipe with metal pipe or valve, flowmeter, pressure gauge and other auxiliary equipment. Flange connection mainly consists of polyethylene flange, steel or aluminium back pressure sleeve flange, steel or aluminium flange, gasket or sealing ring, bolt, nut and other components. Flange connection is to tighten bolts and nuts so that flange joint and flange contact closely to achieve the purpose of connection.
  5、钢与塑料过渡接头连接
  5. Connection of Steel and Plastic Transition Joints
  钢塑过渡接头是通过冷压或其它预制过渡接头连接聚乙烯管道和金属管道。钢塑过渡接头中有抗拉锁环和密封环,它们通常比聚乙烯管道具有更好的密封性能、抗拉和耐压性能。
  Steel-plastic transition joints connect polyethylene pipes and metal pipes by cold pressing or other prefabricated transition joints. There are tension locking rings and sealing rings in steel-plastic transition joints. They usually have better sealing, tension and pressure resistance than polyethylene pipes.
  以上是PE管的连接方式,需要注意的是严禁以任何形式直接在聚乙烯管、管件上螺纹、使用螺纹连接;禁止使用明火烘烤聚乙烯管及管件,直接连接。
  Above is the connection mode of PE pipe. It should be noted that no threading or thread connection is allowed directly on PE pipe or fittings in any form. It is forbidden to use open fire to bake PE pipe and fittings for direct connection.
  今天,聚乙烯连接技术已经非常成熟和可靠。统计表明,聚乙烯管道的泄漏率小于2%,为10万,远小于球墨铸铁管道的2-3%,大大提高了管道的安全性和经济效益,这也是天然气管道较多使用聚乙烯管道的非常重要的原因。
  Today, polyethylene bonding technology is very mature and reliable. Statistics show that the leakage rate of polyethylene pipeline is less than 2%, 100,000, far less than 2-3% of ductile iron pipeline, which greatly improves the safety and economic benefits of the pipeline. This is also a very important reason why polyethylene pipeline is used more in natural gas pipelines.
