Leak detection methods for U-tube heat exchangers
Thread Content
A vertical U-tube heat exchanger, with high-pressure air flowing in the shell side and low-pressure condensate flowing in the tube side. Concerned about leakage issues, low-pressure water should not leak to the high-pressure hot air side ； What impact will high-pressure hot air having on the low-pressure water side have? And how to detect leaks? I think to myself that the pressure resistance of the equipment and pipelines is fine; what happens is simply that there will be fluctuations in the pressure at the water outlet, with air mixed in the water flowing forward. Can leak problems be detected quickly by measuring the salivary flow pressure? The system was originally designed as shown in the diagram; I really can’t understand how he measured this pressure difference.
Why do I feel like this is a level gauge and a liquid level transmitter?
When the leakage is small, it’s likely to go unnoticed； When the pressure difference can be detected, it’s likely that the leakage is already quite severe!
