FAQ - Basket Strainer 150LBS Cast Steel Body
Q1: What is a Cast Steel Basket Strainer 150LBS?
A: A Cast Steel Basket Strainer 150LBS is a basket type pipeline filter with a one-piece sand-cast steel body rated to ANSI Class 150 (19.6 bar / 285 psi at ambient temperature). It removes small impurities from liquid, gases and pipe systems using a perforated screen or wire mesh basket. The large cylindrical basket provides high dirt holding capacity and a large filtration area. It is the standard choice for general industrial service, water, oil, gas and steam piping where the pressure rating is Class 150 or lower.
Q2: What is the size range and end connection available?
A: Cast steel basket strainers 150LBS are available from 2 inch to 24 inch (DN50 to DN600). End connections include Flanged RF (Raised Face) to ASME B16.5, and Butt Weld (BW) to ASME B16.25. Face-to-face dimension follows ASME B16.10. Cover type is bolted cover (B.C.) as standard. For sizes above 24 inch, a fabricated body design is available; please refer to the fabricated body page.
Q3: What body materials are available for the cast steel basket strainer?
A: Body materials include cast carbon steel (A216-WCB), low-temperature carbon steel (A352-LCB, A352-LCC) for service down to -46°C, cast stainless steel (A351-CF8, CF8M, CF3, CF3M), duplex stainless steel (A890-4A) and super duplex stainless steel (A890-5A / A995-5A). WCB is the standard and most economical choice for general water, oil and steam service; CF8M and duplex are selected for corrosive, seawater and offshore service.
Q4: What is the difference between Cast Body and Fabricated Body basket strainer?
A: Cast body basket strainer has a one-piece sand-cast body, typically available from 2 inch to 24 inch (DN50 to DN600). It has uniform thicker walls and is the standard choice for general industrial service. Fabricated body basket strainer is made from welded steel plates, typically available from 8 inch to 36 inch (DN200 to DN900). It offers shorter lead time for large sizes and custom dimensions, and lighter weight in large sizes. For sizes above 24 inch or special project requirements, fabricated type is preferred. Both types are available in Class 150 and Class 300 ratings.
Q5: What screen and mesh sizes are available?
A: Screens are supplied in stainless steel 304SS and 316SS as standard. For corrosive and seawater service, duplex 2205 and super duplex 2507 baskets are available. Mesh sizes include 20, 40, 60, 80, 100, 200 and 400 mesh, tailor-made to customer requirements. For general water and HVAC service, 20 to 40 mesh is common; for fine chemical and pump protection, 80 to 200 mesh is specified. Please specify the mesh size when requesting a quotation.
Q6: How do I maintain a cast steel basket strainer 150LBS?
A: Maintenance is simple: isolate the strainer, depressurize, remove the cover bolts (bolted cover design), take out the basket, clean or replace the screen and mesh, install a new gasket, and reassemble. The bolted cover design allows basket removal without disconnecting the pipeline. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5-1.0 bar. For continuous operation without pipeline shutdown, a duplex basket strainer configuration is recommended.
