Sliding bars for u-tube bundles
Sliding bars for u-tube bundles
(OP)
Does anyone have any guidance as to when these become necessary? Weight of bundle will obviously be a factor, as will number of baffles as it is the friction between baffle and shell which sliding bars are counteracting. Kettle exchangers are a problem as the shell profile changes such that bars not on bottom centre will not remain in contact with each shell/cone section. I have a bundle 1 tonne in a kettle shell.

On larger kettle reboilers, the skid "bars" (often actually pipe) are typically welded to the shell I.D.
