Pressure difference between the high-pressure and low-pressure sides in the formula for calculating the leakage rate when the heat exchange tube ruptures
Thread Content
In the formula for calculating the leakage rate when a heat exchange tube ruptures, which pressure difference refers to the pressure difference between the high-pressure side and the low-pressure side? Is it the design pressure difference, the operating pressure difference, or the difference between the operating pressure on the high-pressure side and the setting pressure of the safety valve on the low-pressure side? I previously searched for related posts in the group, but no definitive answer was found. I’m posting again to seek advice from the experts here; thank you
It’s not the pressure difference at which the safety valve activates; rather, it is this pressure difference that determines whether a safety valve is needed. It is the design pressure difference, as the safety valve must meet the discharge requirements under the maximum design value
Which book is the picture above from?
It is the design pressure; in special cases, the operating pressure cannot guarantee a safe discharge value, so the design pressure of the rupture disc is determined based on the operating pressure
