PE Electro-Fusion Heating Sleeve for Directly Buried Pre-Insulated Pipes
The PE electro-fusion heating sleeve (also known as EF sleeve or hot melt sleeve) is made from high-quality HDPE embedded with a high-temperature resistant nichrome heating mesh. It is designed for the reliable connection and sealing of directly buried pre-insulated pipe joints, ensuring excellent performance in district heating and other pipeline systems.
Material: High-quality HDPE 2480 + Nichrome heating wire
Customizable Size: Suitable for pipe diameters from 200 mm and above
Seamless Connection: Fully fused with pipe surface after heating, forming a leak-proof and durable joint
Excellent Sealing: Resistant to corrosion, temperature variations, axial/radial loads, and bending moments
Quick & Easy Installation: Simple construction process using an electro-fusion welder
District heating pipeline systems
Field joints of pre-insulated pipes
Jointing of steel-reinforced spiral pipes
Joint fittings for hollow wall spiral and structural pipes
Oil and gas pipeline connections
Performance Advantages:
Long service life and anti-aging properties
Superior to heat shrinkable sleeves in sealing and strength
Can be welded before or after polyurethane foaming
Faster construction speed than conventional EF or shrink sleeves
High air-tightness and ring stiffness
