Import Duplex Basket Strainer — Buy in Bulk from Supplier in India

The Duplex Basket Strainer from Specialityvalve is a dual-chamber pipeline filtration device designed for continuous flow systems where shutdown is not feasible. It features two separate strainer baskets with flanged ends, sized from 2 inches to 42 inches, and rated for pressure classes 150 to 300 or PN6 to PN40. The housing is constructed from carbon steel, cast iron, or stainless steel grades including SS304, SS316, SS316L, SS904L, CF8, CF8M, F304, F316, F31L, F51, F3, F55, and F91, selected based on fluid compatibility and corrosion resistance requirements.

Typical industry standards for duplex basket strainers include a mesh size range of 20 to 200 microns, depending on the application. The strainer baskets are removable for cleaning without interrupting flow, and some models incorporate automatic valve actuation to switch between baskets. Material selection follows ASTM A216, A351, and A182 standards for cast and forged components. The design allows for handling higher particulate loads than single-basket units, making it suitable for viscous or debris-prone fluids.

This strainer is commonly used in chemical processing, oil and gas pipelines, power plants, pharmaceutical manufacturing, and metals mining operations where system uptime is critical. Buyers typically specify the material grade, pressure rating, and basket mesh size based on fluid type and contamination risk. Packaging is usually wooden crate or palletized with protective coatings. Trade terms are typically FOB Coimbatore or CIF, with lead times of 4 to 8 weeks depending on customization. MOQ is not stated and must be confirmed directly with the supplier.
