Tube sheets play a vital role in pressure vessels. It is a component inside a pressure vessel used to separate different areas, often called a “partition”. The main function of the tube sheet is to separate the container into several isolated areas to withstand the internal pressure load and ensure the normal operation and stability of the fluid inside the container. In pressure vessels, tubesheets need to meet specific usage requirements, such as withstanding a certain pressure, maintaining high sealing properties, and following specific material and manufacturing process standards. In addition, tube sheets are also widely used in tube-and-tube heat exchangers, boilers, steam turbines, and large central air-conditioning industries to support fixed tubes because their metal materials have strong rigidity and good heat conduction properties.
