Electrofusion Coupling

electrofusion coupling - Efficient connection, safe and long-lasting

This electrofusion coupling is a key connection component specifically designed for gas, water supply and drainage, and municipal pipeline systems.

- Material Advantage: The material is made by injection molding with high-density polyethylene (HDPE) raw material, which is corrosion-resistant, anti-aging, and has excellent wear resistance. It can adapt to complex working conditions ranging from -20℃ to 40℃, and has a service life of over 50 years.
- Electrofusion Connection: A high-precision resistance wire is built-in, and the pipe and pipe fittings are fused at the molecular level through an electrofusion welding machine. The interface strength is higher than that of the pipe body, eliminating the risk of leakage. The installation is convenient and no additional sealing materials are required.

- Structural Design: An integrated thickened pipe wall and positioning protrusions design ensure precise alignment during welding, effectively preventing deviation. The connection terminals on both sides with protective caps not only prevent damage during transportation but also facilitate quick on-site connection.
- Compliance with Standards: It complies with domestic and international industry standards such as GB/T 13663.3,GB/T 15558.3 and ISO 4427, and can be perfectly matched with PE100 grade pipes of the same specification. It is widely used in gas transmission, municipal water supply, sewage treatment and other fields.

- Water Supply Fittings: Made of Sinopec PE100 HDPE, compliant with GB/T 13663 and drinking water hygiene standards, non-toxic, corrosion-resistant, long-term creep resistance.

- Gas Fittings: Exclusively use Borouge HE3490-LS (PE100), bimodal compound, meets GB 15558.1 and ISO gas pipeline standards, excellent RCP/SCG resistance, UV-stabilized, for safe gas distribution.
