Fixed-tube-sheet heat exchangers – tube-sheet sealing surface issues

As shown in the diagram, it has a structure similar to an MFM seal; the sealing surface of the tube sheet protrudes a certain distance inside the cylinder. What is the purpose of this? The red line was added later; if the quality is satisfactory, this step of processing can be omitted. :dizzy:
Easy to assemble. When tightening the upper studs, prevent the gasket from moving inward as the tube sheet and flange are pressed together.
:Thank you for the handshake! It’s still very necessary!

It facilitates centered assembly and ensures that the gasket does not move.
Facilitating centering is one aspect; another reason is for machining the sealing surface. Imagine if it were a flat surface – after machining the sealing surface, would we have to remove the entire middle part? :lol
This small platform plays a crucial role in actual production, especially when graphite wound gaskets are used, where its impact is even more significant
