Electrofusion connection is to use a special electrofusion pipe fitting with embedded resistance wire to make close contact with the connection part of the pipe and energize it, and heat the connection part through the embedded resistance wire to make it integrate until the joint is cooled. Electrofusion connections can be used to connect with PE pipes or spigot fittings of different types and melt flow rates. Electrofusion connections are divided into electrofusion socket connections and electrofusion saddle connections.
