Fixed tube sheets can be used in fixed shell and tube heat exchangers, U-tube heat exchangers or floating head shell and tube heat exchangers. Among them, the floating head heat exchanger needs a floating tube sheet and a fixed tube sheet, and the other two shell and tube heat exchangers only need a fixed tube sheet.
In the calculation of the fixed tube sheet, the axial stress of the shell, the axial stress of the heat exchange tube, and the pull-off force q between the heat exchange tube and the tube sheet are calculated according to various working conditions with temperature diferença. When the strength (or stability) conditions are met, expansion joints are required. In the calculation of the strength of the fixed tube sheet, when the thickness of the tube sheet is determined and no expansion joints are provided, sometimes the strength of the tube sheet is not enough. After the expansion joints are provided, the thickness of the tube sheet may meet the requirements. At this time, expansion joints can also be set to reduce the thickness of the tube sheet, but it should be determined from a comprehensive evaluation of material consumption, manufacturing difficulty, safety and economic effects.
U-shaped expansion joints are commonly used in fixed tube sheet heat exchangers, which have the advantages of compact and simple structure, good compensation, and low price.
With the large-scale chemical equipment and power stations, the diameter of the tube sheet is also becoming larger and larger, and the tube sheet with a diameter of 4m-5m is very common. Large-scale tube sheets are characterized by a large number of tube holes, dense, small aperture, deep, and high requirements for precision and finish.

1. How to judge the quality of tube sheet?
In the inspection process of the tube sheet, the main inspection indicators are the hole position, the hole diameter tolerance, the smoothness in the hole, the presence or absence of burrs, the position of the groove, etc. For the double tube sheet, more attention is paid to the hole position during the inspection process. Hole fit is very important. Generally, it can be guaranteed with a CNC drilling machine. Compared with thick plates, the verticality of holes above 300mm is very important. These thick plates with large diameters require more precise tools and equipment, and the application of special gantry machining centers will become more and more common.
2. What's the method to fix tube on the tube sheet?
One method is by tube to tubesheet welding. Another method is by expandiong tubes, but this way has higher requirement of precision for both tube and tube sheet.
