Tube sheet with partition grooves
Thread Content
The tube sheet sealing surface of fixed-tube-sheet heat exchangers is concave; how should the baffle grooves be designed so as not to affect the seal? How should the seal surface of the partition be machined?
The tube sheet sealing surface is concave – that’s absolutely bizarre
The tube sheet is designed to be concave – could the poster post a picture?
2 baffles can be added on each side of the tube sheet partition groove
Using a concave surface was an error in the design; the tube sheet has already been processed. I don’t want to waste the material and would like to use it again, but I’m not sure about the safety and sealing aspects
It’s made with a groove-like surface seal, right? The thickness of the tube sheet can be recalculated; if there is sufficient margin, it can be changed to a conventional convex shape, or consideration can be given to welding a lining on the sealing surface and then processing it. Without seeing the diagram, it’s not clear what the exact structure is... Theoretically, the design of the sealing surface should not have any impact on its performance.
