Solve for the pressure relationships among the equipment components
Thread Content
Our company has a heat exchanger; the nameplate indicates that the design pressure on the shell side is 6 KG/CM2, while HYDR.TEST.PRESS is set at 8 KG/CM2. If pure water with a pressure of 7 KG/CM2 is used on the shell side, will this constitute overpressure?
It must be overpressured; there will be problems.
It must not exceed the design pressure; all pressure-bearing components are calculated based on this design pressure, and using them beyond this pressure will cause problems.
It doesn’t matter in the short term, but doing this over a long period leads to overload
It is definitely not allowed if the operating pressure exceeds the design pressure.
Sure, the design pressure is there.
What is the purpose of such a high hydrostatic test pressure?

It’s definitely not possible; the design pressure is there to show that.
