Fittings and joints
PE100 fittings from 32 mm to 1,200 mm and the jointing systems that connect them: butt fusion and electrofusion for permanent, self-restrained joints, flanges, compression fittings and saddles where a joint has to come apart.

Joints
Fused joints
HDPE pipe has served municipal and industrial water networks for about 50 years. A heat-fused joint is monolithic: it carries the same pressure as the pipe and does not leak.
Jointing systems
Jointing systems divide into permanent and detachable. The schematic shows the available options.

Butt fusion parameters
Pipes and fittings are butt fused to the single high-pressure procedure of ISO 21307. Heat soak time, bead size and cooling time scale with the nominal wall thickness eₙ. Pick a pipe to read the values for it.

Gauge pressure on the machine depends on its cylinder area: convert the force with the machine maker's table, then add drag pressure.
| Phase | Parameter | Value | Unit |
|---|---|---|---|
| 1 and 2 | Heater plate temperature | 215 ± 15 | °C |
| 1 | Bead-up pressure | 0.52 ± 0.1, plus drag pressure | MPa |
| 2 | Minimum heat soak time | (11 ± 1) × eₙ | s |
| 2 | Heat soak pressure | 0 to drag pressure | MPa |
| 2 | Minimum bead size after heating | 1 + 0.15 × eₙ | mm |
| 3 | Maximum heater plate removal time | See ISO 12176-1 | s |
| 3 | Maximum time to reach fusion jointing pressure | Not specified | s |
| 4 | Fusion jointing pressure | 0.52 ± 0.1, plus drag pressure | MPa |
| 5 | Minimum cooling time in the machine under pressure | 0.43 × eₙ | min |
| 6 | Minimum cooling time out of the machine | A cooling time before rough handling may be recommended | min |
- Bead-up pressure is held until a bead shows all round the circumference of both pipe ends. The pressure is then dropped for heat soak.
- During heat soak, use the lowest pressure that keeps the pipe in contact with the heater plate, up to the current drag pressure.
- Drag pressure is the pressure needed to move the machine carriage and pipe; it is added to the bead-up and fusion jointing pressures.
