What is a Y-Type Strainer?

A Y-Type Strainer is a plumbing device used to remove debris from pipelines, protecting equipment like pumps, meters, and valves from damage. The strainer has a Y-shaped body with a screen inside that traps solid particles while allowing fluid to pass through.

What are the applications of Cast Iron Y-Strainer?

Cast Iron Y-Strainer is used in water supply lines, cooling systems, process lines, and industrial applications to protect pumps, compressors, and instruments from damage caused by rust, scale, and other debris.

What mesh size is available?

Standard strainers come with 20-40 mesh SS 304 perforated screen. Finer meshes (60-100) are available for specific applications. The screen is easily renewable without removing the strainer from the pipeline.

How do I calculate strainer sizing?

Strainer size should be selected based on flow requirements and particle size to be filtered. The strainer body diameter should be approximately 2-3 times the pipe diameter for adequate filtration area and minimal pressure drop.
