Can a fixed-tube-sheet heat exchanger be manufactured in two or more parts?
Thread Content
For the company’s new project, a special heat exchanger is required. The management wants to keep this information confidential, so they have decided to divide the production process into two or more stages, with different manufacturers handling each part before they are assembled together. Do you all think it can be separated? How to divide it?
If classification (Classes I, II, III) is applied, how can manufacturers be instructed on how to conduct supervision and inspection? Do the product certificates need to be issued separately? It seems that many details need to be carefully defined, such as heat treatment (as a whole? Or local? ), voltage withstand test......
Consider this device as a whole. I’m not sure what kind of heat exchanger it is; if it were easy to disassemble, then various manufacturers would produce it by assembling its components.
I really haven’t heard of anyone doing that. If confidentiality is a concern, then the manufacturer should be asked to sign a confidentiality agreement; it’s not reasonable to manufacture them separately. And supervision is always necessary, as confidentiality involves various aspects.
For fixed-tube-sheet heat exchangers that need to be manufactured separately, it is necessary to handle the tube ends at both ends and the heat exchange section in the middle. In the case of U-tube heat exchangers, it is possible to separate the core from the shell for manufacturing. If you need further assistance, please contact us at wxjzhzh@163.com
It wouldn’t be bad. It is recommended to obtain the approval of the special equipment safety supervision department
The main issue is how the entire device provides monitoring and inspection data
Sure. Manufactured by component, with separate inspection for each
