Y strainers work in different kinds of systems, mainly liquid and steam chambers. However, when buying a y strainer for steam service, always ensure that you notify your supplier so they can know the type of y strainer that will work for you. In most instances, you will be provided with a special housing for steam works.
As liquid flows through the y strainer, the screen of the strainer obstructs the flow and collects the debris from the liquid before allowing the process to continue. This obstruction causes the pressure of the liquid to drop, which is commonly referred to as pressure drop in the strainer. The draining plug, which is made up of two metal plates, forms a seal that prevents the liquid from flowing out of the chamber. This keeps the filtered and unfiltered liquid from mixing.
The mesh on the y strainer then traps any form of impurities from the liquid and prevents them from flowing to other parts of the system. This is how the y strainer works to protect dirt particles from getting to the main system parts. Y strainers work in high-velocity systems where the pressure is up to 6,000 psi.
How the y strainer works makes it a better choice in comparison to basket strainers which are built for pressures of up to 1500 psi. There are different ways in which you can connect the y strainer to your pipeline. You can either thread it or bolt it to the flange. This majorly depends on the kind of material used on the strainer. Y strainers are made out of different materials, mainly stainless steel, iron and cast iron. Some are made from carbon and bronze.
