VESSEL ATTACHMENTS Piping
INCORRECT CORRECT
Do not attach pipes directly to the vessel if
possible (vented systems). Allow them to
enter through large clearance holes. Flexible
boots may be used to seal out dust if neces-
sary.
Do not run an attached pipe vertically to its
first support point. This will suspend the
vessel and destroy accuracy. All pipes should
be run horizontally away from the vessel.
Increase as much as possible the distance
between the vessel and the first pipe support.
Avoid long vertical runs of pipe when pos-
sible, particularly when they are restrained
from movement in the vertical direction.
This is because any thermally-induced ex-
pansion/contraction of the vertical pipe will
be translated into detrimental vertical forces
on the vessel, directly affecting accuracy.
Use flexible hose to make the connection to
the vessel if possible. Do not use the flexible
hose to compensate for an initial offset in the
pipes.
