FAQ - Basket Strainer 150LBS Fabricated Body
Q1: What is a Fabricated Basket Strainer 150LBS?
A: A Fabricated Basket Strainer 150LBS is a basket type pipeline filter with a welded steel body (fabricated from steel plate and pipe) rated to ANSI Class 150 (19.6 bar / 285 psi at ambient temperature). Unlike cast body basket strainers, the fabricated body is welded from wrought steel materials (WPB, A106, SS304, SS316, SS304L, SS316L), allowing larger sizes up to 36 inch and custom dimensions with shorter lead time. It is the standard choice for large diameter pipeline, district heating main lines and custom projects.
Q2: What is the size range and end connection available?
A: Fabricated basket strainers 150LBS are available from 2 inch to 36 inch (DN50 to DN900). End connections include Flanged RF (Raised Face) to ASME B16.5 (size under 24 inch) or ASME B16.47 (size above 24 inch), 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. Larger sizes and custom dimensions are available on request with shorter lead time than cast body.
Q3: What body materials are available for fabricated basket strainer?
A: Fabricated body materials include wrought carbon steel (A234-WPB, A106 Gr.B), stainless steel (SS304, SS316, SS304L, SS316L) and duplex stainless steel (2205, 2507). A234-WPB is the standard wrought carbon steel fitting material, widely used in fabricated strainer and piping systems; A106 Gr.B is the seamless carbon steel pipe for high-temperature steam and boiler service. SS304 and SS316 are selected for general corrosion and chloride-containing media respectively; duplex 2205 and 2507 are used for seawater, desalination and offshore service.
Q4: What is the difference between Fabricated Body and Cast Body basket strainer?
A: Fabricated body basket strainer is made from welded steel plate and pipe, typically available from 2 inch to 36 inch (DN50 to DN900). It offers shorter lead time for large sizes and custom dimensions, and lighter weight in large sizes. Cast body basket strainer has a one-piece sand-cast body, typically available from 2 inch to 24 inch (DN50 to DN600), with uniform thicker walls. For sizes above 24 inch or special project requirements, fabricated type is preferred; for standard sizes up to 24 inch, cast type is more economical. 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 district heating 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 fabricated 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. For large diameter fabricated basket strainers (above 24 inch), a davit arm design is recommended for heavy cover lifting without crane. 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.
