The value for heating element temperature is between 200° C - 220° C.
The
smaller
the pipe wall the
higher
the temperature.
PE 100
The standard value for heating element temperature is 220° C.
Increase the change-over time and the welding pressure time at PE 100 as fast as possible !

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
