Thin tube sheet heat exchanger
Thread Content
Let’s discuss thin tube sheet heat exchangers together. Those with more experience could please explain things such as their advantages, disadvantages, applicable scenarios, design considerations, and performance parameters. As a type of tube sheet, the thin tube sheet has been in use for many years both domestically and internationally. It enjoys a wide range of applications and holds promising prospects due to the following characteristics: 1. Thin tube sheets save material, are easy to process, and result in lower manufacturing costs. 2. Because they are thin, they generate less thermal stress, making them suitable for use in situations where there are large temperature differences in the fluid flowing through the shell side. 3. The calculation formulas for them are simple. However, since the theories related to the calculation of thin tube sheets both domestically and internationally are not yet mature, and the calculation methods remain empirical in nature, there are often concerns regarding their strength, which imposes certain limitations on their use. However, numerous application examples have shown that thin tube sheets are not lacking in strength, and over the years there have been no reports of safety incidents resulting from the use of thin tube sheets. Therefore, it is highly worthwhile to discuss issues such as the strength of thin tube sheets and their application environments in order to reach a consensus, thereby further expanding the scope of application for such tube sheets.

Advantages: Excellent performance in absorbing the expansion difference in the shell side! Disadvantage: Weak pressure resistance! Usage: Suitable for applications with low design pressure and a large temperature difference between the tube side and the shell side! Design considerations: I’ve never designed anything before, so I don’t dare to speak rashly!
I’ve never encountered this; how thick should the thin tube sheet be?
The thickness is generally around 15 mm. The connection methods between the tube sheet and the shell or flanges include surface bonding, embedding, and welding. The brother on the third floor is right; since the tube sheet is thin, the temperature difference stress is low, making it suitable for situations where there is a large temperature difference between the tube side and the shell side. Computational theory is not yet mature; calculations are based on empirical formulas. I just looked up some information; I don’t dare keep it to myself. Experts, please add more!
I’ll try to handle it myself; I hope those who are experts have designed similar things and can share their experience on such matters. Thank you!
The SW64.05 version now includes calculations for thin tube sheets. In the past, it was always done by referring to AD specifications. Perhaps referring to the calculation of the tube sheet in waste heat boilers could also work.
Thanks for the reminder from above; I’ll go check SW6 right away
Learn* it a bit. I’m from Harbin Institute of Technology too! :lol
