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.
