For fixed-tube-sheet heat exchangers, the operating pressure on the tube side is -0.015; how should the design pressure be determined?

A negative pressure condition has not been designed for, but I think it’s necessary to set the value in the negative pressure direction. Is 1.25 times appropriate? Also, if the strength design is proper, this negative pressure should be very small!

The design pressure can be set at -0.02 MPa

Tube side operating pressure: -0.015; material: TA2. Shell side operating pressure: 0.3; material: S31603
