Butt Fusion
About
Thermo fusion is a process which involves simultaneous heating of two HDPE, UPVC or PE pipe ends meant to be joined.
Once a molted state is attained, the two surfaces are then brought together under controlled pressure for a specific cooling time and a homogeneous fusion joint is formed. The resultant joint is fully resistant to end loads and has comparable performance under pressure to the pipe itself.
Butt Welding Machine
Our fusing machines are equipped with an electrical heater plate which is used to raise the temperature of the pipe ends to the required fusion temperature.
We can join PE80 and PE100 for pipe sizes from 63mm to 320mm of the same SDR.
The butt welding machines used to weld PE pipes have controls to ensure the welding parameters are strictly adhered to. The following parameters are controlled:
- Heater plate temperature
- Ovality and alignment
- Interface pressure
- Bead width
- Heat soak time
- Changeover time
"We guarantee our work and with these controls premature failure of the weld does not occur. The field conditions under which PE pipe is welded have a considerable effect on the strength of the joint".
Our fusing machines are available for hire.
