The basics of butt fusion

For butt fusion with a heating element, the parts to be joined (pipe/pipe, pipe/fitting or
fitting/fitting) are heated to fusion temperature in the fusion area and are fused under
pressure without the use of additional materials.
The heating element butt fusion joint must be done with a controllable equalization
pressure.
Only the same type of materials are to fuse.
The wall thicknesses in the fusion area need to be the same.
Correct
Only the same wall thicknesses in the fusion area!
The equalization pressure (phase 1) and the fusion pressure (phase 5) are identical. The
heat soak pressure (phase 2) is significant lower, but the contact between the
pipe/fitting and the heating element needs to be ensured.
