Issues with the working steam in heat exchangers
Thread Content
During the design of the heat exchanger, the operating steam pressure was set at 0.35 MPa. Now, during the commissioning phase, for certain reasons, the steam pressure needs to be increased to 0.45 MPa. How can we determine whether the heat exchanger can withstand such a high pressure of steam? How should this be calculated? Also, in our department, the steam is used not only in heat exchangers but also in the jackets of various equipment. How should this be calculated? Can we use steam with a pressure of 0.45 instead of 0.35 as before? Friends with design experience or production experience, please help answer! Thank you
Generally, there are no problems with heat exchangers; note that this is true only usually, as heat exchangers are designed to meet rigidity requirements rather than strength requirements. However, for jacketed vessels, recalculation is required, especially when the jacket pressure increases, as this can easily cause the calculation of the external pressure on the inner cylinder to fail.
Thank you, but the steam at 0.45 pressure needs to be delivered by tomorrow. It seems that no one is responding today; there are too many devices, and it’s really troublesome to check each one individually.
