Flange sealings and static sealings
The following procedure describes how to fit flange sealings and static sealings.
Action
Check the flange surfaces. They must be even and free from pores. 1
It is easy to check flatness using a gauge on the fastened joint (without sealing com-
pound).
If the flange surfaces are defective, the parts may not be used because leakage could
occur.
Clean the surfaces properly in accordance with the recommendations of ABB. 2
Distribute the sealing compound evenly over the surface, preferably with a brush. 3
Tighten the screws evenly when fastening the flange joint. 4
O-rings
The following procedure describes how to fit o-rings.
Note Action
Ensure that the correct o-ring size is used. 1
Defective o-rings, including damaged
or deformed o-rings, may not be used. Check the o-ring for surface defects, burrs,
shape accuracy, or deformation. 2
Check the o-ring grooves. 3
The grooves must be geometrically correct and
should be free of pores and contamination.
Lubricate the o-ring with grease. 4
Tighten the screws evenly while assembling. 5
Check that the o-ring is not squashed outside
the o-ring groove. 6
