PE/Polyethylene Electro Heating Fusion Sleeve for Directly Buried
Pre-Insulated Pipes
With over 20 years of expertise, our company is a leading
manufacturer of PE/Polyethylene Electro Heating Fusion Sleeves,
holding a utility model patent and recognized as the organizer of
the National Symposium on Electro-Fusion Welding Belt Production
and Application. Our products are exported to Turkey, Sudan, UAE,
Japan, Russia, Kazakhstan, and beyond.
Product Features
Our Electro Heating Fusion Sleeve is a high-quality HDPE sheet
embedded with a nichrome net, designed for welding pre-insulated
pipes using a specialized electric heating welder. Customizable in
size, it accommodates pipe diameters from 200mm and above. Applications - District thermal heating system construction
- Pre-insulated and oil pipeline joint welding
- Hollow wall spiral pipe joint fitting
- Structural pipe joint fitting
- Steel-reinforced spiral pipe joint fitting
Performance Advantages - High-Quality Materials: Made with HDPE 2480 and high-temperature-resistant nichrome net.
- Superior Sealing: Achieves full fusion with pipes, ensuring excellent sealing,
corrosion resistance, and long service life.
- Durability: Withstands axial and radial forces, bending moments, and
temperature variations.
- Seamless Design: Prevents polyurethane foam leakage, offering high connection
strength and air-proof performance.
- Efficient Construction: Simple production process and fast installation compared to
heat-shrinkable or traditional electro-fusion tapes.

Why Choose Our Product?
Our seamless hot-melt sleeve outperforms traditional
heat-shrinkable and electro-fusion tapes in anti-aging, connection
strength, and ring stiffness. It allows pre-welding of jacket tubes
followed by polyurethane foaming, significantly speeding up
construction. Ideal for heating and petroleum pipeline joint
connections, it ensures reliable quality, comprehensive service,
and compliance with industry standards.
