Table for PP
Additional to the given bead-up force and to the welding force the moving force of the support must be added !
The standard value for heating element temperature is 210 °C ± 10 °C (410 °F ± 50 °F) .
The smaller the pipe wall the higher the temperature.

Remaining under the cool-down time for up to 50% is allowed under the following conditions:
•
prefabrication under workshop conditions
•
low additional pressure at unclamping
•
no additional pressure during further cooling down
•
load onto the workpieces only after being completely cooled down
•
Join parts with wall thickness ≥15 mm
