HDPE Polyethylene Electro Heating Fusion Sleeve Fitting for Directly Buried Preinsulated Pipe

PE / Polyethylene electric heating fusion tape for Metal reinforced polyethylene spirally corrugated pipe.It is a kind of connecting pipe fitting what is widely used on anti-corrosion, especially on Directly buried pre-insulated pipes field joint. It is made by Polyethylene sheets complex with the electro-fusion wire.

Used for:
 District heating systems
 Field joint welding of pre-insulated pipes & oil pipelines
 Spiral pipe, structural pipe, and steel-reinforced pipe joints

Features:
High-Quality Materials: Made from premium HDPE 2480 and high-temperature nickel-chrome mesh for superior durability.
Strong & Seamless Bond: Ensures full fusion with pipes, offering excellent sealing, corrosion resistance, and long service life.
Mechanical Strength: Withstands axial, radial, and bending forces, as well as temperature fluctuations.
Customizable Sizes: Available for pipes ≥200mm diameter;       tailored dimensions upon request.
Certified Performance: Complies with industry standards (see test data for density, tensile strength, elongation, etc.).

Advantages Over Alternatives:
Faster Construction: Allows welding before polyurethane foaming, speeding up installation vs. heat shrink tape.
Enhanced Durability: Superior aging resistance, ring stiffness, and connection strength.
Leak-Proof: Prevents polyurethane leakage with airtight sealing.
Global Reach: Exported to Turkey, UAE, Japan, Russia, and more. Patented technology with 15+ years of manufacturing expertise.
