HDPE通用增强网状结构壁管的三种链接方式

作者: admin    来源:http://www.laobingguandao.com  时间:2019-08-29    人气:
  HDPE通用增强网状结构壁管主要有三种连接方式:热熔套挤压焊接、热缩管(带)连接、电热熔带焊接。重要工程可采取两种连接方式组合连接,应具有较为成熟的连接结构和连接器产品及施工工艺,这是三种常用的连接方式。
  There are three main connection modes of spiral bellows reinforced by steel strip: hot melt sleeve extrusion welding, heat shrinkable pipe (strip) welding and electric hot melt strip welding. Important projects can be connected by two kinds of connection modes. They should have more mature connection structure, connector products and construction technology. These are three commonly used connection modes.
  1. 热熔套挤压焊接
  1. Extrusion welding of hot melt sleeve
  是采用特殊的热风出焊工具,将管道两端加热,焊枪挤出熔融聚乙烯材料,将聚乙烯材料在两端本体连接的方法。这是将聚乙烯材料熔化成一个整体连接,一个刚性连接。
  It is a method of using special hot air welding tool to heat both ends of pipeline, extrude melt polyethylene material by welding torch, and connect polyethylene material to the body at both ends. This is to melt polyethylene material into a whole connection, a rigid connection.
  2、热缩管(带)连接
  2. Heat shrinkable pipe (belt) connection
  内层采用纤维增强聚乙烯热收缩带,外层采用热收缩管。热收缩管表面涂有热熔胶,加热后与相邻管端紧密连接。

  Fiber reinforced polyethylene heat shrinkage belt is used in the inner layer and heat shrinkage tube is used in the outer layer. The surface of the heat shrinkable tube is coated with hot melt adhesive, which is tightly connected with the adjacent end of the tube after heating.
  3.电热熔带焊接
  3. Electrothermal Welding
  它是一种通过向嵌入在外部接触面的加热元件充电而产生的高温连接方法。这是一个刚性连接。电热熔焊接结构:墙面镶嵌聚乙烯焊接区电阻丝,靠近两端外表面,采用热带紧固电阻。同时,在出水管的壁上有较强的可拆卸工具支撑。界面两侧的聚乙烯相互扩散,经过充分的冷却和固化,切断电源,形成可靠的连接。
  It is a high temperature connection method by charging the heating element embedded in the external contact surface. This is a rigid connection. Electrothermal fusion welding structure: the wall is inlaid with polyethylene welding zone resistance wire, near the outer surface of both ends, using tropical fastening resistance. At the same time, there is strong disassembly tool support on the wall of the outlet pipe. Polyethylene on both sides of the interface diffuses with each other. After sufficient cooling and curing, the power supply is cut off to form a reliable connection.
