3. THREADED CONNECTIONS

3.1 TIGHTENING TORQUES

The tightening torques in the table below are
standard torques and only apply to dipped
threaded connections.

The property codes are stamped on the nut and
bolt, except on the clamping flange bolt. The
clamping flange bolt is recognised by a
constriction between the hexagonal bolt head
and the flange. This constriction is absent in
standard flange bolts.

connections

The bolt stem length L is the length of the bolt
between the bolt head and the nut.
If a component is attached with several bolts, all
bolts must first be tightened to the specified
torque, and subsequently by the angular
displacement.
