tube sheet hole bridge
Thread Content
For example: According to the standards, the hole spacing on the tube sheet for heat exchange tubes with a diameter of 25 is 32. Can the spatial distance be increased arbitrarily?
If it is enlarged arbitrarily, can the flow rate and heat exchange efficiency be maintained?
Of course, the standard does not require compliance with this rule
Whether to increase it or not can be determined by the equipment specialists, but whether an increase will have an impact on heat exchange is determined by the process design.
That rule seems to specify the minimum distance, right? As long as it is larger than this and meets the design requirements, it’s fine.
