China Electrofusion Elbow Pipe Fittings - High-Quality Suppliers & Factory for PE Connection Solutions
Key Feature Details
Material and 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.
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 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.
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 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, and the installation process is simplified.
Frequently Asked Questions
What materials are the electrofusion fittings made of?
The fittings are made of high-quality polyethylene (PE100 grade) material with integrated heating elements, such as resistance wires, embedded inside to ensure a secure, scientific design and robust strength.
How does the electrofusion connection process work?
An electrofusion welding machine is used to energize the internal resistance wires. The heat generated melts the PE material at the joint interface. Once cooled and solidified, it forms an integrated leak-free structure.
What are the primary advantages of using electrofusion fittings?
They offer high connection strength, exceptional corrosion resistance, and simple operation. By automating the heating process, they minimize human errors and connection variations during installation.
Can these fittings withstand seismic activity and harsh soil conditions?
Yes. The connections can withstand earthquakes up to magnitude 8. Additionally, the PE100 material resists slow crack growth (SCG) and chemical erosion from acids, alkalis, and salts, making them ideal for buried environments.
What is the expected service life of these fittings?
Due to their highly durable PE100 composition, resistance to corrosion, and immunity to rust and biological growth (algae/bacteria), these fittings have an operational service life of over 50 years.
