5. Welding Table for PE pipes DVS norm version 2207-1
The following tables show the values to be applied during the welding cycle as per previous instructions and graph.
However in order to clarify once again the meaning of these values please kindly note:
t1
=
Time requested for the bead formation to be done with pressure value =
P1
+ inertial pressure
t2
=
Time requested for the continual heating to be done with pressure value =
P2
+ inertial pressure
t3
=
Time requested for the change over
t4
=
Time requested for bringing up the pressure at the value of pressure =
P1
+ inertial pressure
t5
=
time requested for cooling down to be done with pressure value =
P1
+ inertial pressure
Important
Remember always to add the value checked of inertial pressure to the P1 and P2 values !!!!!!!
