Strainer is a type of control device used in various industries for filtering liquids, gases, and other fluids. It is designed to remove solid impurities from the fluid to prevent damage to downstream equipment and ensure the quality of the final product.
Strainers are typically installed in the piping system and come in different sizes and shapes to fit the application. They can be made of various materials such as stainless steel, brass, and plastic. The most common types of strainers include Y-strainers, basket strainers, and duplex strainers.
Y-strainers have a Y-shaped body and a removable screen that captures debris while allowing the fluid to flow freely. Basket strainers have a basket-shaped body and a removable basket that holds the straining element. Duplex strainers have two parallel straining elements and are designed to allow continuous operation by diverting the flow of fluid from one element to the other.
Strainers are commonly used in the water treatment industry to filter water before it enters the treatment process. They are also used in the oil and gas industry to filter drilling fluids and in the chemical industry to filter chemicals before they enter the production process. Overall, strainers play an essential role in maintaining the efficiency and reliability of various industrial processes.
