PE Electrofusion Threaded Insert

The DN110 Electrofusion Threaded Adaptor is an essential component for transitioning between pipeline systems and threaded equipment. It comes in two types: Female Thread and Male Thread. The Female Thread adaptor (electrofusion socket end + internal thread) is commonly used to connect equipment with external threads, such as fire hydrants and valves. The Male Thread adaptor (electrofusion socket end + external thread) is suitable for connecting to equipment with internal threaded ports. Both types are made from high-quality HDPE material, which ensures a permanent seal with the PE pipe via electrofusion. The threaded end features standard pipe thread dimensions (e.g., G2½), ensuring precise engagement with equipment. Their reinforced structure effectively disperses stress at the threaded connection, preventing loosening or leakage during long-term use. These adaptors are widely used in municipal water supply and firefighting systems, especially at points requiring frequent disassembly for maintenance. They combine the reliability of electrofusion sealing with the flexibility of threaded connections.

A PE Electrofusion Threaded Insert is a specialized plastic fitting integrated into a plastic pipe using the electrofusion method. Its outer diameter features a pre-defined fusion zone with conductive coils designed for uniform heating. When energized, the insert's outer wall heats up, causing complete fusion between the insert and the pipe wall. This creates a permanent, monolithic connection while providing a reliable internal thread. This allows for future connection to threaded valves, instruments, or other components with axial threaded ports, meeting the specific need for a leak-free seal that can also be conveniently disconnected and reused.

Selecting the right threaded electrofusion fitting is crucial. Each product is clearly marked with all essential information. Before purchase or on-site installation, confirm three key points: 1) The electrofusion socket diameter must match the pipe being welded. 2) The thread type, size, and pitch must exactly match the equipment or fitting you are connecting to. An incorrect choice can lead to installation failure, leaks, or pressure loss. Correct identification is vital for ensuring installation quality and seal integrity.
