HDPE pipe Electrofusion tape for Thermal Oil Pre-Insulated Pipeline Girth Weld
Sturcture of EF Band
HDPE sheets embed with nicochrome net by heating.
Application
Connection of PU foaming pre-insulation oil pipeline joint fittings
Features
1. The EF band are specially cut in to narrow piece to fit for trough of wave of SRCP, EF band is welded along with cutting edge of two pipes, ensuring strenght of joint.
2. EF band is made by the same material as that of SRCP, the same material and melt flow rate ensures good result of sealing.
3. EF band is light and could be easily operated by setting parameters on adjstment instruments.
Installing/Operation
We can support with our customers two connection methods of SRCP,
1. " Inside welding, outside EF band"
2. " Inside welding, outiside HSS",regarding information of heat shrink sleeve connection, we will introduce it separately in other chapter.
Performance:
1. Waterproof;
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.
HDPE Electro fusion Tape for Hollow Wall structured pipe
Performance:
- The same material and melt flow rate ensure the good effect of seal after fusion welding.
- Light in weight, easily operating.
- Waterproof; High adhesion, good air tightness ,corrosion resistant capacity,long service life and convenient operation
- 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.
