Couldnta said it better

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Normally NTIW baffles are used to address concerns about flow-induced vibration because they eliminate the long unsupported tube spans in the window region, plus the design allows you to place intermediary support baffles (both ends cut) in between the segmental baffles.

The disadvantage is that they require a larger diameter shell to accomplish the same heat transfer.

Sir,
May I request you to elaborate following point, if possible with a schematic :

Christine74, nice link, thanks for that
