HDPE Electrofusion Welding Fitting for Direct Burial Insulated Pipelines

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

Technical Specifications:

• Excellent waterproof and sealing properties
• Withstands soil movements and pipe stresses
• Superior aging and corrosion resistance
• Consistent insulation thickness to match pipe layer
• Faster and simpler installation compared to heat-shrink alternatives

Export Experience:
With over 15 years of production experience, our electro-fusion sleeves are exported to Turkey, Sudan, UAE, Japan, Russia, Kazakhstan, and more. We hold a utility model patent and have organized national symposia on electro-fusion technologies.
