Electrofusion connection is to insert the composite pipe into the electrothermal fusion pipe, so that the electric heating wire embedded in the inner surface of the pipe is electrified and heated. First, the inner surfaces of pipes are melted to produce a melt, which melts and expands to fill the gaps between pipes until the outer surfaces of pipes also produce a melt. After cooling and forming, the tubes are closely connected into a whole.
Characteristics of electrothermal fusion connection:
The electrothermal fusion connection technology is convenient and quick to construct, and can be used for connection, installation, assembly and unified welding.
The welding reliability is good, and the strength and density are better than other connection methods.
Keep the inner wall of the pipeline smooth without affecting the circulation area.
