3 Dismantling/Assembly 3.3 Intermediate Service (IS), check points
3.3 Intermediate Service
(IS), check points
3.3.1 Introduction
This chapter consists of check points that can be
done when the separator has been dismantled for
Intermediate Service but before it is assembled.
Other check points that can be done only in
conjunction with the assembly are described in
the assembly sections.
3.3.2 Corrosion
Evidence of corrosion attack should be looked for
and rectified each time the separator is
dismantled. Main bowl parts such as the bowl
body, bowl hood and lock ring must be inspected
with particular care for corrosion damage.
Always contact your Alfa Laval representative if
you suspect that the largest depth of the
corrosion damage exceeds 1,0 mm or if cracks
have been found. Do not continue to use the
separator until it has been inspected and given
clearance for operation by Alfa Laval.
Cracks or damage forming a line should be
considered as being particularly hazardous.
Non-stainless steel and cast iron parts
Corrosion (rusting) can occur on unprotected
surfaces of non-stainless steel and cast iron.
Frame parts can corrode when exposed to an
aggressive environment.
DANGER
Disintegration hazard
Inspect regularly for corrosion damage.
Inspect frequently if the process liquid is
corrosive.
