PE Electrofusion Sleeve and Electro Melt Band Making Machine Line

PE Electro Fusion Welding Sleeve:
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



INTRODUCTION
Electrofusion weldable joint is a pre-cut high-quality HDPE sheet embedded with nicochrome net. It is used as polymer pipe welding materials or fittings, which is installed by a special electric heating welder.
The tape size can be customized. It can be used for a big range of pipe diameter from 200mm.



Application:
1. District thermal heating system construction
2. Pre-insulated pipes field joint welding and oil pipes joint welding;
3. Hollow wall spiral pipe joint fitting
4.Structure pipe joint fitting
5. Steel reinforced spiral pipe joint fitting

Performance:

1. Waterproof; High adhesion, good airtightness, corrosion resistant capacity, long service life and convenient operation
2. Able to withstand axial forces initiated by axial movements of the pipe in the ground;
3. Able to withstand radial forces and bending moments;
4. Able to withstand effects of temperature and temperature variations.
5. Have the same thickness of the line pipe insulation layer.

Size and deviation of the electrofusion mesh

Resistivity of electrofusion mesh should comply with the following standard

Resistivity of electrofusion mesh
