HDPE Hollow Wall Spiral pipe Electrofusion Tape Joint Fittings
1.HDPE Electro-fusion belt/Tape is a kind of special connection pipe fittings which is made of HDPE sheet by secondary processing and composite special Nickel alloy mesh. It is mainly used for the connection of supply heat pipeline, oil pipeline, natural gas pipeline and anti-corrosion insulation pipeline.
2.According to the different application scope of electro-fusion belt / tape, it can be divided into the following three types: 1. Electro-fusion tape for hollow wall corrugated/structured pipe; 2. Electro-fusion belt for Metal reinforced HDPE spirally corrugated pipe; 3. Electro-fusion tape for buried pre-insulation pipe.
3.Performances of electrofusion tape:
Waterproof;
Able to withstand axial forces initiated by axial movements of the pipe in the ground;
Able to withstand radial forces and bending moments;
Able to withstand effects of temperature and temperature variations.
Have the same thickness of the line pipe insulation layer.
HDPE Electro fusion Tape for Hollow Wall structured pipe
Performance:
1.The same material and melt flow rate ensure the good effect of seal after fusion welding.
2.Light in weight, easily operating.
3.Waterproof; High adhesion, good air tightness ,corrosion resistant capacity,long service life and convenient operation
4.Able to withstand axial forces initiated by axial movements of the pipe in the ground;
5. Able to withstand radial forces and bending moments;
6. Able to withstand effects of temperature and temperature variations.
7. Have the same thickness of the line pipe insulation layer.
