PE/Polyethylene Electro Heating Fusion Sleeve for Directly Buried Pre-Insulated Pipe
Our PE/Polyethylene Electro Heating Fusion Sleeve is a specialized
HDPE fitting designed for the reliable and efficient joining of
directly buried pre-insulated pipes. The sleeve features a pre-cut
HDPE sheet embedded with a high-temperature resistant nichrome
heating mesh, enabling robust, leak-proof, and corrosion-resistant
joints through electro-fusion welding.
- High-Quality Materials: Manufactured from HDPE 2480 and durable nichrome mesh for superior heat resistance and long service life.
- Strong, Seamless Fusion: Achieves complete fusion with the pipe, ensuring excellent sealing, corrosion resistance, and the ability to withstand both axial and radial forces as well as thermal variations.
- Wide Application Range: Suitable for pipe diameters from 200mm (customizable sizes available).
- Easy & Efficient Installation: Quick and convenient construction using a dedicated electric heating welder; supports rapid field jointing.
- Proven Performance: The design provides higher connection strength, improved sealing, and enhanced anti-aging properties compared to heat-shrink and standard electro-fusion tapes.
- District heating system construction
- Field joint welding of pre-insulated and oil pipes
- Fittings for hollow wall spiral pipes, structural pipes, and steel-reinforced spiral pipes
- Joint sealing and corrosion protection for pre-insulated pipeline networks
