China Suppliers Factory Electrofusion Elbow Fittings for PE Pipe Connections - High Quality Electric Melting Accessories
Key Feature Details
Material & Structure
Made of polyethylene (PE) material, with components such as resistance wire embedded inside to ensure scientific design, strong strength and good sealing performance.
Working Principle
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.
Main Advantages
It has high strength, corrosion resistance and is easy to operate, reducing the impact of human factors on connection quality.
Common Types
Including electrofusion direct, electrofusion tee, electrofusion elbow and electrofusion flange, etc.
Application Field
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.
- Excellent seismic performance capable of withstanding an earthquake of magnitude 8.
- Industry-leading resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
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 and Long Service 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.
- Does not corrode or rust, preventing the growth of algae and bacteria.
- Perfectly suitable for both soil burial and open-air environments.
Convenient and 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, simplifying the installation process.
Frequently Asked Questions
Q: What materials are used to construct these electrofusion fittings?
They are made of high-quality polyethylene (PE100 grade) material with embedded internal resistance wires, ensuring a scientifically designed, strong, and well-sealed connection.
Q: How does the electrofusion welding process work?
An electrofusion welding machine is used to energize the resistance wire inside the fitting. This melts the PE material at the joint, which then cools and solidifies into a single, integrated structure.
Q: How reliable is the joint strength after welding?
The joint is highly reliable. After welding, the interface strength exceeds that of the pipe body itself, with a tensile elongation at break of over 500%, completely eliminating traditional joint leakages.
Q: What is the estimated service life and chemical resistance of these fittings?
Constructed from PE100 grade, they resist chemical media like acids, alkalis, and salts, offering a service life of over 50 years. They do not rust, corrode, or promote bacterial/algae growth.
Q: Can these fittings withstand extreme environmental conditions like earthquakes?
Yes, they feature industry-leading resistance to slow crack growth (SCG) and rapid crack propagation (RCP), providing excellent seismic performance capable of withstanding earthquakes up to magnitude 8.
Q: What are the primary application fields for electrofusion fittings?
They are widely applied in high-pressure fluid transmission engineering, including municipal water supply systems and gas transmission networks.
