PE electrofusion fittings are key components that connect polyethylene (PE) pipes and fittings by heating embedded resistance wires with electric current, causing them to melt together. They are widely used in projects requiring high sealing performance, such as gas and water supply systems.
Core Principle and Main Features
By embedding resistance wires inside the fitting, heat is generated when electric current passes through, causing the contact surfaces of the fitting and inserted PE pipe to melt simultaneously. Once cooled, they fuse into a strong, unified piece.
Main Advantages
Excellent sealing: Achieves integration of the joint and pipe, fundamentally solving interface leakage issues.
High reliability: The welding process is controlled by a welding machine, minimizing the impact of work environment and human factors.
Strong adaptability: Effectively resists ground movement, pipe end loads, and uneven settlement.
Corrosion resistance: Made of the same material as PE pipes, ensuring long service life.
