HEX tube layout: 30 vs 60 degree
HEX tube layout: 30 vs 60 degree
(OP)
Hello,
I have gone out for bids on 2 different exchangers, one is condensing on the shell side and the other vaporizing on the shell side. One exchanger manufacturer has recommended to use a 60 degree tube layout. They say that this reduces the possibility of vibration in the exchanger. This is the first time that I have heard this in my young career. Do any of the veterans out there see this as a recommended practice? Especially for 2-phase conditions in the shell?
I can see that a 60 degree layout may reduce the amount of fluid impinging on tubes, is there a better explanation out there for this?
Thank you,

However, all of these factors are also dependent upon baffle spacing, type of baffle, shell size, window area, etc.
