Forged EN 10025-2 S235JR Carbon Steel Baffle Support Plate For Heat Exchanger
Baffles in general can come in various shapes and designs, such as straight, segmental, or helical, depending on the specific requirements of the equipment and the desired effect on the fluid flow pattern. They are commonly used in industrial processes, especially in heat exchangers, pressure vessels, and reactors. Baffles are structural components that are placed inside these equipment to enhance heat transfer efficiency, promote fluid mixing, and provide mechanical support.
