Instructions for Use
Installation of ConFlat Flange
For ConFlat flange connections, fix the two flanges with the screws as shown in the
following figure (a protective screen can optionally be used).
Figura 34
Use the required number of screws:
16 for CFF 6"
20 for CFF 8"
Attach the units and tighten each screw in turn. Repeat the sequential tightening
until the flange faces meet. Tighten the screws with a torque
of 20 Nm.
For ConFlat flange we recommend the usage of high strength steel bolts only.
To facilitate assembly and dismantling, it is optional to apply
Felpro C-100 high temperature lubricant to the screw threads protruding from the
flange and between the nuts and flange.
In some cases, the connections can be made only with the bolt in the lower side.
Be careful when tightening nuts and bolts to avoid creating dents on the
