HDPE Pipe Butt Fusion Welding Machine Fusion Safety Reminders

A few procedures to keep in mind are:

1. Make sure the fusion unit is well maintained and working properly.
2. Pipe should be entering the machine straight and level. This will help reduce drag (the effort it takes to move the pipe ends together).
3. When facing the pipe ends, always face to the machined stops. This assures the pipe ends will be square to each other, with no gaps or voids.
4. Align the OD of the pipe ends. There should be no more than 10% of the wall thickness in misalignment, to maintain full joint strength.
5. Check heaters to make sure they are operating properly and the faces are clean. Wipe the heaters with a clean non-synthetic cloth before making each joint. Other materials may melt and stick to the surface of the heater.
6. Use the pipe and fitting manufacturers recommended heater temperatures and heat times.
7. Keep in mind that gauge pressure and fusion pressure are two different things. Use the pipe and fitting manufacturers recommended fusion pressures (normally 75psi of surface area to be fused). Gauge pressure should be calculated using a fusion pressure calculator specific to the machine being used.
8. Cool the newly made fusion joint, in the machine, under fusion pressure until the joint is cool to the touch (approx 1 minute per inch OD minimum).
9. After removing the pipe from the machine, wait at least 20-30 minutes before rough handling the joint or pressurizing the system.
