Section 7: Flushing Instruction
This instruction describes the guidelines that must be followed in order to assure that a
system is flushed to a degree that complies with the cleanliness class required by Emerson
in order to assure that the system components will work satisfactorily.
CAUTION
Flushing through Bettis components are not allowed!
All Bettis components are cleaned before shipment and therefore they do not require
flushing. Some types of components will be damaged if system flushing is done through
these components and other components will make flushing impossible because flushing
cannot be done through them.
7.1
Flushing Procedure
Piping system must be flushed before it is connected to Bettis components. In the event
that this is not possible, all Bettis components must be by-passed during flushing.
Each individual customer (yard) is free to choose which flushing method that is preferred to
use, as long as one of the internationally recognized flushing standards is used.
CAUTION
Do not flush through Bettis equipment!
Flushing through Bettis equipment might damage parts of the equipment and induce
withdrawal of the Guarantee!
