Series leakage of heat exchanger
Thread Content
1. With two media under equal pressure or with only a small pressure difference, how does leakage occur? Some colleagues say that the hot medium leaks into the cold medium. Is this related to stress? 2. When the pressures of the two media are different, does the medium with the higher pressure flow into the medium with the lower pressure? Are there any unusual possibilities? I seek advice from the experts
Thermal expansion – you must know this term! ;P
I mean. . . . . . ? Can you explain it clearly?
The two media will react and also interfere with each other
Unless there is a very large pressure difference between the two sides of the shell, leakage will occur in both directions; whenever there is leakage, it happens in both ways, with just a greater amount of fluid leaking from the high-pressure side to the low-pressure side
The so-called equal pressure is merely a rough concept; as long as there is the slightest difference, high pressure will flow towards low pressure. This pressure is also related to temperature, and it is necessary to make judgments based on the actual conditions.
Analyzing the components of the tube and shell media through laboratory testing is the simplest, most direct, and effective method. As long as the qualitative analysis is missing, that’s fine. Repair and seal leaks. There’s no need to worry about it. Your goal is to avoid leaks and not disrupt production.
What I’m trying to say is, were my colleague’s words too absolute? Also, what is the pressure difference required for high pressure to penetrate into low pressure?
I agree with you; what you said makes sense.
Everyone has their own opinions, right? Nothing is absolute, isn’t that so? Wearing them on both sides would be more appropriate, right?
After reading what everyone said, I thought of a question: for the faucet at home that doesn’t have much pressure, if it’s submerged in a basin of water, will the water in the basin flow into the faucet?
