Y-Strainers are devices for mechanically removing unwanted solids from liquid, gas or steam lines by meansof a perforated or wire mesh straining element. They are used in pipelines to protect pumps, meters, controlvalves, steam traps, regulators and other process equipment.

Strainers arrest pipeline debris such as scale, rust, jointing compound and weld metal in pipelines, protecting equipment and processes from their harmful effects, thus reducing downtime and maintenance. Use of rightly selected strainers at correct locations (usually upstream) is a must to protect expensive and critical downstream equipment such as pumps, flow meters, steam traps, control valves etc.
