Machined Products - Discs with Perforations

Machined metal discs with perforated structures are commonly used as tube sheets in heat exchangers or coolers. These tube sheets feature a large number of precisely drilled holes for installing the ends of heat exchange tubes. The tubes are fixed and sealed through these holes, connecting to the shell to form fluid channels. Their primary purpose is to support and fix the heat exchange tubes, guiding fluid flow inside and outside the tubes to achieve heat transfer. They are frequently used in high-efficiency heat exchange equipment in industries such as chemical, petroleum, and energy. The peripheral bolt holes are used to connect to the main body of the equipment, ensuring structural stability.
