HDPE Electro Fusion Tape fittings for pre-Insulated pipeline joint
Product Description
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
Application:
1. District thermal heating system construction,
2. Pre-insulated pipes field joint welding and oil pipes joint welding;
3. Preinsulated bonded pipe system for directly buried hot water networks;
4. Three PE/PP layers with foam jacket insulation pipes connection;
5. Steel pipes anti-corrosion etc.
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.
