Pressure in the shell and tube sides of the heat exchanger
Thread Content
I would like to ask everyone: if the operating pressure on the tube side of the heat exchanger is 0.1 MPa and the operating pressure on the shell side is 1.0 MPa, what should be the design pressure? If the design pressure of the tube side is 0.12 MPa, how should the pressure of the shell side on the heat exchanger tube bundle be understood? Shouldn’t the heat exchanger tube bundle be under pressure from both the inside and outside? Can the tube bundle withstand a pressure of 1.0 MPa in the shell side? I work on the production line, so I don’t quite understand this issue. Please give me some guidance. Thank you!
It can handle it; everything is calculated based on the most severe conditions.
Under what conditions is the calculation done? Could you explain it in more detail? I still don’t quite understand it. Thank you
We need to consider the most extreme possibilities.
It means that each of the high-pressure and high-temperature conditions you mentioned can be met.
Calculating and checking under the six operating conditions will pose no problems
In simple terms, the strength under the pressure in the shell side of the heat exchange tube must also be evaluated, but this is not necessary for the tube box
I also want to ask; I’m not sure how to make the choice
As a designer, all these factors you mentioned need to be calculated. Therefore, the design pressure for the tube side and the shell side can be determined separately; it’s also acceptable to use atmospheric pressure for the tube side. One thing to keep in mind is that if the pressure on the tube side is higher than that on the shell side, leakage testing of the pipe fittings during the manufacturing process must be taken into account.
Does leak detection at the pipe end fall under leak testing? ?
