Industrial Grade Excellence
Taper Basket Strainer Manufacturer, Fabricated SS Tapered Strainer Supplier in India
VVIOK Industry is an established, premier industrial filtration equipment manufacturer based in Ahmedabad, Gujarat, celebrated for engineering the Best tapered basket strainer in india. In heavy-duty fluid handling systems, pipeline strainers must deliver high dirt-holding capacity while allowing quick basket removal and minimal pressure drop. Engineered with a specialized angled profile, our high-precision Tapered Basket Strainer assemblies provide smoother internal fluid velocity transition and faster sediment settling than conventional straight cylinders, safeguarding downstream pumps, compressors, valves, and flow meters across chemical, petrochemical, oil & gas, pharmaceutical, and water treatment installations.
At the core of every assembly is a precision-engineered stainless strainer basket, constructed from certified AISI 304, AISI 316, or AISI 316L austenitic stainless steels, as well as Duplex and Hastelloy alloys for severe corrosive applications. The unique tapered basket geometry ensures self-centering during installation and effortless extraction from the housing during maintenance shutdowns. Engineered to endure severe operating conditions, each Tapered basket strainer heavy duty model combines a thick perforated metal backing cage (1 mm to 6 mm perforations) lined with durable Dutch weave or square wire mesh down to 20 microns (600 mesh), preventing basket deformation under differential pressures (ΔP) up to 10 bar.
As a certified designer and fabricator compliant with ASME Section VIII Division 1 and ASME B16.34 codes, VVIOK Industry specializes in custom fabricated basket strainers designed for both simplex and duplex pipeline installations. Unlike mass-produced cast units that are restricted by rigid mold dimensions, our fabricated vessels can be tailor-engineered with custom nozzle elevations, offset inlet/outlet ports, davit-arm quick-opening covers, and internal support rings. This fabrication flexibility allows us to offer the Best tapered basket strainer configurations tailored to exact client piping layouts with zero compromise on structural reliability.
To meet diverse plant throughput requirements, our standard Tapered basket strainer sizes range from 1 inch NB up to 48+ inches NB (DN25 to DN1200) with pressure ratings spanning ANSI Class 150#, 300#, and 600# in raised-face (RF), flat-face (FF), and ring type joint (RTJ) flanged connections. Every unit delivers an extraordinary 4:1 to 6:1 free straining open area ratio relative to the nominal pipe diameter. Each unit undergoes 100% hydrostatic shell pressure testing, radiographic weld inspection, and dye-penetrant checks, accompanied by complete EN 10204 3.1 Material Test Certificates (MTC).

1. Design Standards & Dimensional Compliance:
- Design Codes: ASME Boiler and Pressure Vessel Code Section VIII Division 1, ASME B16.34 (Valves Flanged, Threaded and Welding End), MSS-SP 81.
- Flange Standards: ASME B16.5 (1/2" to 24") and ASME B16.47 Series A/B (26" to 48"), DIN / EN 1092-1.
- Open Straining Area: 400% to 600% (4:1 to 6:1 free open area ratio relative to nominal pipe cross-section).
2. Materials of Construction (MOC):
- Housing Shell: Heavy-wall Carbon Steel (ASTM A106 Gr. B / IS 2062), Austenitic Stainless Steel AISI 304, 304L, 316, 316L, 904L, Duplex 2205, Super Duplex 2507, Hastelloy C-276.
- Internal Strainer Basket: Heavy-duty tapered stainless steel basket with perforated sheet (1.0 mm to 6.0 mm round perforations) lined with precision woven Dutch weave wire mesh (20 to 500 mesh / 25 µm).
- Flanges & Hardware: High-tensile ASTM A193 B7/B8 bolting with spiral wound SS 316 / PTFE / Viton gaskets.
3. Sizing & Pressure Ratings:
- Standard Pipe Sizes: 1" NB to 48" NB (DN25 to DN1200, with custom engineering for oversized lines up to 60").
- Pressure Classes: ANSI Class 150#, Class 300#, Class 600# (PN10, PN16, PN25, PN40, PN64).
- End Connections: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ), or Butt-Weld ends.
4. Hydraulic Performance & Flow Characteristics:
