Pipe fitting and installation

1. Coupling principle
The electrofusion coupling is a process that inserts the composite tube in into the plastic electrofusion tube in advance and energizes the heating wire embedded in the inner surface of the tube to generate heat. The inner surface of the tube is first melted to produce a melt, and then the melt expands and fills the gap of the tube fittings until the outer surface of the tube also produces a melt. The two melts fuse with each other, and after cooling down and forming, the tube and the tube fittings are tightly coupled.

2. Features of tube connection
A. Convenient construction, unified welding.
B. Good weld-ability, excellent strength and sealing property.
C. It is suitable for HDPE raw material of different marks and melt flow rate.
