Calculation of the leakage rate due to tube rupture in heat exchangers
Thread Content
Hello everyone. I would like to ask for advice regarding the calculation of the leakage rate when the heat exchange tubes in a heat exchanger break. I’ve reviewed many literature formulas, and all of them refer to the high pressure inside the tubes; whether there is a liquid phase or a gas phase inside, the pressure is higher on the inside than on the outside. How is the leakage rate calculated when a heat exchange tube ruptures under conditions of high pressure outside the tube? Is the pressure inside the pipe the same as high pressure? Thank you!
When designing a heat exchanger, the tube side is usually arranged on the high-pressure side. If the operating pressure on the shell side is high, then by increasing the design pressure of the tube side to a level where overpressure does not occur, a safety valve becomes unnecessary.
