A Y type strainer is a pipeline filtration device designed to remove unwanted solids from liquids, gases, or steam. Its Y-shaped body allows debris to collect in a mesh screen while maintaining smooth flow with minimal pressure drop. Fabricated Y type strainers are custom-built (rather than cast) and are typically used for larger sizes, higher pressures, special materials, or specific industrial requirements. Fabricated Y type strainers are critical components across industries such as oil & gas, petrochemical, power generation, water treatment, HVAC, marine, and food processing. Their primary function is to protect expensive equipment by filtering out debris while maintaining system efficiency and reliability.
Having the involvement of “Y Type Strainers” in name, it is needless to say that fabricated y type strainers are most suitable for inclined or horizontal pipelines where dust is hard to remove from the flowing fluids. This type of strainers is cylindrical in shape so it can be fixed properly in the pipe to provide useful filtration. Being an inexpensive kind of strainer, it is used in millions of pipelines to remove debris from fluids. Fabricated Y type strainers are made up of Mild steel, stainless steel or alloysteel. It has a bolted cover along with blow off drain connections. Having flanged ends/butt-weld ends of the dimension of an inch to 24 inches, it is compact in size. Although it is easy to install, its size doesn’t allows it to hold high amount of dirt. When it comes to pressure, the rating lies in between 150# to 1500# and the strainer doesn’t affect it while removing dirt with process stream. Our fabricated Y type strainers are easy to carry and install because of its low weight and compact size. You also get options to choose the most suitable type of fabricated strainer for your pipelines. We make larger size and pressure of fabricated strainers available for prospective clients on request.
