PE Electro Fusion Girth Welding Joint
Introduction |
It is a kind of special-purpose pipe connection, which is made by embedding specific electric heating melt welding wire in the basis of high quality PE sheet with special technicals. |
Aplication Scope |
1.District heating system(pipe),district thermal heating; 8. Used for joint of Pre-insulated Pipeline, HDPE double-wall corrugated pipes.
|
Advantages |
1. Waterproof; 2. Able to withstand axial forces initiated by axial moments of the pipe in the ground; 3. Able to withstand radial forces and bending forces; 4. Able to withstand effects of temperature and temperature variatations. 5. Have the same thickness of the pipeline insulation layer. 6. Perfect product instead of Heat Shrinkable Sleeve. |
Specifications |
Pipeline size: from Ø 108 to Ø 1760mm Wrap Thickness: 4mm—12mm Sleeves width:100mm,150mm,200mm,300mm,450mm, 500mm,600mm,700mm,800mm |
