The values apply for the butt welding of pipes according to DVS 2207, 2208 DIN 16932
They are guide values for saddle welding; they may deviate and must be redetermined
if necessary!

Additional to the given bead-up force and to the welding force the moving force of the support must be added !
Table for PP
The standard value for heating element temperature is 210° C +/- 10° C.
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
