Cast Iron and Carbon Steel strainers
Y Strainers (or "Wye Strainers") mechanically remove debris in pipeline with a cylindrical straining element, often called a screen. They can be placed in horizontal or vertical pipelines (downward only) and require regular cleaning of the screen for proper operation.
Basket strainers are used to mechanically remove debris in pipelines with a straining element that is shaped like a basket. Basket Strainers are typically used in horizontal pipelines. In most cases, they provide more open area for debris collection than a Y strainer and need less frequent cleaning.
