Pipeline Y-strainers (wye strainers) offer a compact and economical means of straining debris from pipelines. Keckley Y-strainers are furnished standard with drain connections and pipe plugs. Most commonly, Y-strainers are fitted in the field with nipples and drain valves to permit the strainer screen to be cleaned while the system is still in process. By opening the drain valve while the system is under pressure, the debris trapped in the screen is "blown" through this connection helping to reduce system shut-downs for maintenance and cleaning.
Keckley simplex pipeline basket strainers are used in piping applications where a greater screen area to pipe area ratio is required. By providing a greater screen area than a Y-strainer, you are optimizing the total open area and minimizing potential pressure loss through the basket. Simplex strainers are used to protect pipelines, valves, and spray nozzles from water flow problems. They reduce the necessity for frequent cleaning and provide a cost and time saving benefit with less downtime.
Keckley duplex continuous flow basket strainers are used in continuous flow applications where the process cannot be shut down for cleaning. Some examples are lubrication systems, industrial or marine oil burners, chemical plants, cooling lines in power plants, compressors, condensers, ink supply lines to printing presses, and for water lines to cooling towers and pumping stations where water is taken from lakes or rivers. The primary benefit of a duplex basket strainer is to provide uninterrupted downtime for maintenance and cleaning.
