    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.
