As shown in the picture below, a vertical heat exchanger, why does the heat exchange tube in the middle adopt this structure?

Only the middle pipe has this structure, and the other pipes do not use a sunken structure.

Just one tube is designed with this structure, and hundreds of other tubes are of conventional design. How much thickness can be reduced?

It's not worth my while to reply to this post, so I'll leave it at that.
