Heat exchanger tube sheet
Thread Content
In GB/T 151-2014, what are the structural types of tube sheets? How were their mechanical models determined respectively?
The commonly used types are mainly divided into flange-mounted tube sheets, welded tube sheets, and clamped tube sheets; their specific structural forms and welding methods can be found in Appendix I of GB/T151-2014
The calculation model should be one of those shown in Figure 7-3 of GB/T151-2014

These two questions originated from inquiries made by experts in pressure vessel design renewal from other organizations. I feel the scope is quite broad, so I’d like to ask everyone for their advice. I think 7.4.4-6 and 7.4.10 in GB/T151-2014 are mechanical models, as mentioned in 7.4.1.3, along with appendices K, L, and M, which also represent 4 mechanical models. I’m not sure if there are any more fundamental and in-depth materials; I earnestly ask those with more experience for their guidance.
According to his proposal, structural classification is definitely related to the computational models, so I personally think it should be based on those models or classifications that were mentioned. That is, those BCE types in SW6
The topic is too broad; it is recommended to refer to GB/T 151, which provides clear guidance.
As for the calculation model of the tube sheet, the central tube holes are not considered; the tube sheet is simplified to a circular plate, with either simply supported or fixedly supported edges. Regarding the connection methods, refer to section 151 for details :)
