Why is the heat exchanger keeping leaking?
Thread Content
Our plant has a wax oil and fresh water heat exchanger used to generate steam for the 3.5MP steam drum, but why is it constantly leaking? Can’t fix it? The material is fine. Is there a problem with the process design?
What type of heat exchanger? Where is it leaking? Is it oil or water?
What type of heat exchanger? Where is it leaking? Is it oil or water? What is the oil temperature? How long is the heat exchange tube?
Is it the gasket that is leaking or the weld seam?
It is a U-type heat exchanger with tube bank leakage (oil leakage).
To be more specific, the location of the leakage, the operating parameters of the heat exchanger, etc
Where in the pipeline is there a leak? What is the specific nature of the leak? If the shell side is at high pressure, there should be no oil leakage; it should be water that enters the oil instead. Please provide a detailed explanation!
Also, what are the pressures of oil and water respectively?
It must be that the amount of paraffin oil fluctuates greatly or the temperature of the incoming water is too low
