It’s fine to choose a slightly larger diameter for the safety valve inlet pipe, right?

Due to changes in the calculation data, the diameter of the inlet pipe for the safety valve selected now is a bit larger than what is actually required; there should be no problem, right?
I’m not sure whether the poster is referring to the fact that the diameter of the existing pipeline is smaller than that of the safety valve’s inlet pipe, or whether the safety valve selected is too large It is not advisable for the diameter of the inlet pipe to be smaller than that of the safety valve inlet ； Choosing a safety valve that is too large can also lead to problems such as frequent tripping under accident conditions
In fact, as long as the parameters of the safety valve remain unchanged, the diameter of the inlet pipe of the safety valve and the diameter of the pipes connected to it can be adjusted accordingly
With the relief valve’s discharge pressure and leakage rate remaining unchanged, it should be fine to increase the diameter of the inlet pipe. However, for the outlet pipe, the diameter can be increased but not decreased; otherwise, the flow velocity might increase, leading to subsequent problems such as erosion or vibration
