For the tube sheet of heat exchangers, how thick is the thickest one you’ve ever seen?
Thread Content
In general terms, the thickness of a tube sheet is only a few centimeters. But today I heard about a heat exchanger with design parameters of 300°C and 100 barG; for such an exchanger, the calculated thickness of the tube sheet is over 1 meter. . .
The world is full of wonders; the heat exchangers used in heavy oil chemical processing can be extremely large
200mm is the largest seen so far!
I’ve seen 500. One meter? It’s too thick…
The high-pressure heaters in the power plant are designed for a pressure of 45 MPa and a temperature of around 350 degrees; the tube sheet has a thickness of 600–700 mm. I’ve never encountered one that’s 1000mm thick; what’s its diameter?
The design parameters of the 1.5m power station are all higher than what I mentioned. .
I think there’s an issue with the calculations; it shouldn’t be this thick. Moreover, according to GB150 standards, such a thick tube sheet exceeds the allowed thickness limits, so it cannot be used directly as it doesn’t meet the standards
The material selection needs to be reconsidered; materials with good high-temperature performance should be used, such as CrMo steel. Even if stainless steel is required, it is possible to use CrMo steel for surfacing on top of stainless steel – in any case, materials with excellent high-temperature properties should be employed.
