12.2 Tightening Torque
Tightening Torque
Flange for Suction and Pressure Connection
Flanges with corresponding screws and sealing elements are to be used in ac-
cordance with the information provided by the flange manufacturer.
Respective tightening torques should be gathered from the information pro-
vided by the flange manufacturer or as per standard ISO 6162.
Mounting Screws
As per DIN 13 or ISO 68, in individual cases, tightening torques should be
checked in accordance with VDI 2230.
Mounting screws for SAE-A, SAE-B and SAE-C flange:
Sealing Plugs Form E with ED Seal (Reference Values)
Straight Screw-in Sockets Form E with ED Seals (Reference Values)
The data on the tightening torque in this segment is considered as refer-
ence values only. Preference should be given to the data provided by
each manufacturer of the particular machine part!
