Identifying the Primary Causes of Plate Heat Exchanger Failures
Under the combined influence of significantly high tube pass pressure and the differential temperature load in the large tube shell pass, the fixed tube sheet heat exchanger fails to meet strength requirements. To address the substantial temperature difference stress, an expansion joint is necessary, but it induces significant stress between the tube and tube sheet under high tube pass pressure, rendering it unable to meet strength conditions. Consequently, alternative heat exchange types, such as U-shaped tube types, are chosen.
