Y-Strainer are special devices, used for mechanically removing solids from flowing liquids or gases by using a perforated or wire mesh straining element/equipment. These strainers are used in pipelines to protect equipment such as pumps, meters, control valves, steam traps and regulators. These strainers are generally used where the amount of material to be removed is small and when frequent straining is not needed. Y type strainer are widely used for handling steam, these compact and cylindrically shaped strainers are very strong and can handle high pressures. These strainers can be installed both horizontally as well as vertically. Cast iron, bronze, carbon steel, or stainless steel are the common materials used to manufactured these specialized strainers. Iron is most widely used because it costs the least.
