China Suppliers Factory - PE Electrofusion Elbow Fittings for Secure Polyethylene Pipe Connections
Key Feature Details
Made of polyethylene (PE) material, with components such as resistance wire embedded inside to ensure scientific design, strong strength and good sealing performance.
By means of an electric fusion welding machine, the resistance wire in the fitting is energized, the PE material at the connection part melts and cools and solidifies to form an integrated structure.
It has high strength, corrosion resistance and is easy to operate, reducing the impact of human factors on connection quality.
Including electrofusion direct, electrofusion tee, electrofusion elbow and electrofusion flange, etc.
Widely used in gas transmission, water supply system and other fluid transmission engineering.
Core Performance Characteristics
High Strength Connection
After welding, the interface strength is higher than that of the pipe body, and the tensile elongation at break is greater than 500%, forming an integrated structure and completely solving the leakage problem of traditional pipe joints. It has excellent seismic performance and can withstand an earthquake of magnitude 8. The ability to resist slow crack growth (SCG) and rapid crack propagation (RCP) is industry-leading.
Excellent Sealing Performance
A uniform sealing layer is formed by melting resistance wires, effectively preventing the leakage of liquids or gases. It is suitable for high-pressure fluid transportation systems such as gas and water supply.
Corrosion Resistance & Long Life
Made of polyethylene (PE100 grade), it is resistant to erosion by chemical media such as acids, alkalis and salts, and has a service life of over 50 years. It does not corrode or rust, and does not promote the growth of algae/bacteria. It is suitable for soil burial and open-air environments.
Convenient & Efficient Construction
Electrofusion connection can be completed in just a few minutes, reducing the time of manual operation. It is less affected by external environments (such as humidity and temperature) and human factors, and has high reliability. No glue or adhesive is needed, and the installation process is simplified.
Frequently Asked Questions (FAQ)
What materials are the electrofusion fittings made of?
The fittings are made of high-quality polyethylene (PE100 grade) material, featuring scientific engineering with embedded resistance wires inside to ensure maximum strength and superior sealing performance.
How does the electrofusion welding process work?
During installation, an electrofusion welding machine energizes the embedded resistance wires. This melts the PE material at the joint interface, which then cools and solidifies to create a fully integrated, leak-free structure.
How reliable is the joint strength of electrofusion fittings?
The connection is exceptionally strong, with joint interface strength exceeding the pipe body itself. It features a tensile elongation at break greater than 500% and is built to withstand earthquakes up to magnitude 8.
Are electrofusion fittings resistant to corrosion?
Yes, the PE100 material is highly resistant to chemical erosion from acids, alkalis, and salts. It does not rust, corrode, or promote algae/bacterial growth, making it ideal for both soil burial and open-air installations.
What is the expected lifespan of these fittings?
These electrofusion fittings are designed for long-term durability, offering a reliable service life of over 50 years under normal operating conditions.
Where are electrofusion fittings typically applied?
They are widely utilized in critical utility networks, including high-pressure gas transmission, municipal water supply systems, and other fluid transmission engineering projects.
