Detailed Product Description

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.

Features
 
  • 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.
Applications
  • 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
