Pipeline strainers, also known as filters, are mechanical devices that remove unwanted particles, debris, or contaminants from a fluid stream in a pipeline system. They are typically installed upstream in the pipeline of sensitive equipment, such as pumps, valves, and meters, to protect them from damage and maintain efficiency.
Pipeline filters use a screen or mesh to trap and remove particles from the fluid stream as it passes through the strainer. The trapped particles can be removed manually or automatically, depending on the type of strainer. Some strainers are equipped with a blowdown valve or a backwash feature to clean the strainer element without interrupting the fluid flow.
