This list includes a wide range of materials and components used in various industrial applications. From metals like stainless steel, aluminum, and cast iron to specialized alloys such as Monel and Haynes, each material has unique properties that make it suitable for specific environments. Rubber compounds like Buna-N and Viton are often used for sealing and gaskets due to their resistance to heat and chemicals. Graphite-based materials, including expanded graphite and rubber graphite boards, are commonly used in high-temperature and low-friction applications.
Additionally, the term "working medium" refers to the substance that flows through a system, such as water, oil, or gas, while "shell test pressure" is a critical measurement in ensuring the integrity of pressure vessels. Understanding these materials and their properties is essential for selecting the right components for engineering and manufacturing processes.
Fixed Tube Heat Exchanger
Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall.
Advantages: simple and compact structure, high pressure resistance, low cost and easy to clean the tube side.
Disadvantages: Risk of blockage when the tube is damaged or needs to be replaced.
When the difference between the wall temperature of the tube bundle and the shell or the coefficient of linear expansion of the material is large, a large thermal stress will be generated in the shell and the tube bundle. A flexible compensation ring (also called expansion joint) should be installed on the shell to reduce the thermal stress.
