Cast Steel Basket Strainer Flanged to ANSI 150 with 304 Stainless Steel Mesh (mesh size is 40 mesh or 400 micron). Allows a large flow rate with minimal pressure drop. This basket strainer is great for petrochemical or other applications where straining needs to occur with as little as possible pressure drop. Much less than the equivalent size y strainer. All cast steel basket strainers are sand blasted then coated with a heat resistant primer. Designed to ANSI B16.34 with flanges to ANSI B16.5 and tested in accordance with API 598. This unit is cast as one part and not fabricated like many other basket strainers. This costs more in production but gives the unit a much longer life and makes it a stronger pressure vessel.
