Expansion joint calculation
Thread Content
The shell side pressure is 6.6 MPa with a temperature of 310 degrees, while the tube side pressure is 0.5 MPa at a temperature of 290 degrees. How should the expansion joints for such a heat exchanger be designed and calculated?

A pressure of 6.6 MPa is not suitable for the use of expansion joints; at such high pressures, the expansion becomes greater, the stiffness increases, and the axial pulling force also rises. As a result, the connection between the heat exchange tubes and the tube sheet cannot hold, leading to a dead loop. Expansion joints for heat exchangers are suitable for applications with large temperature differences and low pressures
