Description
Polyethylene Electric Heating Fusion Wrap/Sheet for welding closure/connecting/jointing pre-insulated Pipe- More than 15 years of production experience
- The organizer of the National Symposium on the Production and Application of Electro-fusion welding belt
- Recipient of utility model patent for electric heating sleeve
- Exporting the electro-fusion welding tape to Turkey, Sudan, UAE, Japan, Russia, Kazakhstan and other countries.
Electricfusion tape 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 fitting4. Structure pipe joint fitting5. Steel reinforced spiral pipe joint fitting
Performance:1. Adopt high-quality raw material: HDPE 2480 produced by China Petroleum &Chemical Corporation and High-temperature resistance nicochrome net.2. Fully fused with the pipe after electric heating with good sealing effect, corrosion resistance and long life service.3. Able to withstand axial forces initiated by axial movements of the pipe in the ground;
4.Able to withstand radial forces and bending moments;
5. Able to withstand the effects of temperature and temperature variations.
Easy welding parameter set up . The fusion welder can work with 380V or 220V.
