Selection of design pressure for heat exchangers
Thread Content
Could some expert please advise me on the design pressure for the heat exchanger? Thank you. Operating pressure: The shell side is at -0.1/2.0 MPaG, and the tube side is at -0.1/0.8 MPaG. What should be the design pressures for the shell side and the tube side? Are there any standards for learning knowledge in this area? Please give me some advice; thanks~!
The design pressure is easy to determine: for the shell side, it’s -0.1/2.2 MPa, and for the tube side, it’s -0.1/0.88 MPa
When calculating, should -0.1 correspond to -0.1? Does 2.2 correspond to 0.88? I don’t know how to work with these 4 design pressure values for the shell side and tube side! Thank you!

It’s difficult to determine the most demanding operating conditions for a heat exchanger; therefore, it’s necessary to calculate for each possible condition. If it’s not possible to establish a proper correspondence between them, then four calculations will be required
You’re welcome, sharing happiness:lol
