The technology of HDPE double-wall corrugated pipe is gradually matured in continuous use. Its hot-melt connection includes the following three methods:
Electrofusion joints are generally used in spaces where they are constrained by the installation site and cannot be thermally coupled. When the same thermoplastic pipe is connected, a special electrofusion pipe fitting is inserted, and the electrofusion fitting device is energized to the electrofusion pipe member, and the required heat is generated according to the pre-embedded electric resistance wire inside the electrofusion pipe member, and the pipe and the electrofusion pipe member are cooled after cooling. Even become a whole. The characteristics of electrofusion connection are convenient connection, rapid speed, good joint quality and small disturbance of external factors.
2. Socket type hot melt connection
In order to improve the application pressure of the socket connection, it is also possible to add a casing at the socket part. The socket type hot melt connection is to insert the pipe insertion end and the socket end away from the heating and soften, and then agilely penetrate and cool down. Compare strong connections.
3. Direct hot melt connection
The pipe joints are heated and directly joined by heat fusion.
The above is the relevant content of the "Technical Introduction of HDPE Double Wall Corrugated Pipe Connection" to be introduced by the polyethylene composite pipe manufacturer today.
