The AL 250 is a butt fusion machine for PE and PP pipe from Ø 75 to Ø 250 mm. It welds pipe walls up to PN 32. Power supply is 230 V, Single phase. Total installed power is 4.8 kW. On site you will need a generator of at least 6.5 kVA. Welding pressures and times come from the DVS 2207 parameter table; the full procedure is under Technical Guides below. It ships in 1 wooden crate. Crate sizes and weights are listed under Packaging & Transport.
- Place pieces in the clamps; insert the trimmer and face until 100% contact.
- Remove trimmer, insert heater (~220 ℃); push at 0.15 N/mm² to form the lip.
- Equalize temperature at almost zero pressure (0.01 N/mm²) with heater in place.
- Remove heater; join the pieces at 0.15 N/mm².
- Hold joining pressure for the required time, then release.
- Leave the joint to cool under the specified time.
| Wall (mm) | Lip (mm) | Heat (s) | Remove heater (s) | Fuse (s) | Cool (min) |
|---|---|---|---|---|---|
| up to 4.5 | 0.5 | 45 | 5 | 5 | 6 |
| 4.5–7 | 1 | 70 | 6 | 6 | 10 |
| 7–12 | 1.5 | 120 | 8 | 8 | 16 |
| 12–19 | 2 | 190 | 10 | 11 | 24 |
| 19–26 | 2.5 | 260 | 12 | 14 | 32 |
| 26–37 | 3 | 370 | 16 | 19 | 45 |
| 37–50 | 3.5 | 500 | 20 | 25 | 60 |
| 50–70 | 4 | 700 | 25 | 35 | 80 |
Visibility
Butt welds are visible and can be redone on the spot; EF welds hide inside the socket and need experienced welders.
Hard to reach places
EF wins: tiny machine, cable tip electrodes. Works above ground, in pits, anywhere.
Simplicity
Butt welding forgives workmanship errors; EF has zero tolerance and fails only at pressure test.
Material conditions
EF demands matching MFI, round pipes, clean surfaces, stable voltage; butt is unaffected by these.
Cost
Butt is far cheaper: no copper wire sockets every 6/12 m.
Strength
A correct butt weld is the strongest point of the line (the 'lip' adds wall thickness).
