6.4.3 Inspection for cracks
Check the separator parts for cracks. It is
particularly important to inspect for cracks in
rotating parts, and especially the pillars
between the sludge ports in the bowl wall.
Cracks can occur from cyclic material stresses
and corrosion. Keeping the separator and its
parts clean and free from deposits will help to
prevent corrosion attacks.

Disintegration hazard
All forms of cracks are potentially dangerous as they
reduce the strength and functional ability of

Always replace a part if cracks are present.

Disintegration hazards
Always contact your Alfa Laval representative if you
suspect that the depth of the damage exceeds 0,2
mm for bowl body and bowl hood (0,5 for other
parts).
Do not continue to use the separator until it has
been inspected and given clearance for operation by
Alfa Laval.
