Action
1. Check the flange surfaces. They must be even and free from pores.
It is easy to check flatness using a gauge on the fastened joint (without sealing
compound).
If the flange surfaces are defective, the parts may not be used because leakage could
occur.
2. Clean the surfaces properly and in accordance with ABB recommendations.
3. Distribute the sealing compound evenly over the surface, preferably with a brush.
4. Tighten the screws evenly when fastening the flange joint.
Action
1. Ensure that the correct o-ring size is used.
2. Check the o-ring for surface defects, burrs,
shape accuracy, etc.
3. Check the o-ring grooves.
The grooves must be geometrically correct and
free from pores and contamination.
4. Lubricate the o-ring with grease.
5. Tighten the screws evenly when assembling.
