Stainless Steel Filter Cylinders Supplier

Stainless Steel Filter Cylinders

Anping CREMOTIVE Wire Mesh Products CO., LTD offers a comprehensive line of Stainless Steel Filter Cylinders—versatile elements designed to integrate seamlessly into existing filtration systems or customized filter vessels. Constructed from precision-woven or perforated stainless steel mesh, these cylindrical filter elements deliver reliable performance in fluid clarification, particulate removal, and gas or liquid separation applications.

Design and Construction

• Mesh Core and Support: At the heart of each filter cylinder lies a woven mesh sleeve or perforated sheet formed into a cylinder. For fine filtration, we use stainless steel mesh (304 or 316L) with wire diameters as small as 0.05 mm and openings down to 5 µm. The mesh is wrapped around or supported by a perforated stainless steel core (typically 0.5 mm to 1.5 mm thick) with evenly distributed holes to provide radial strength.

• Structural Reinforcement: Spiral or longitudinal support rods are welded or crimped to the outer mesh to prevent collapse under differential pressure. The support rods are generally thicker (0.5 mm to 1 mm) gauge stainless steel, ensuring the filter cylinder withstands pressure differentials up to 10 bar (145 psi) or higher, depending on design.

• End Caps and Sealing: End caps are stamped or welded from solid stainless steel plates (grade 304 or 316L) and often include O-ring grooves for leak-free installation. Standard end-cap configurations include flush top, recessed top, and dome top designs, accommodating a variety of filter housings and mounting plates. Gasket materials are selected based on operating temperature and fluid compatibility (e.g., EPDM, Viton, PTFE).

Material Selection and Surface Treatment

• Core Materials: 304 stainless steel is used in general industrial settings; 316L for corrosive or high-purity environments. If ferritic stainless steels (e.g., 430) are acceptable, a cost-effective option is available for non-corrosive applications.

• Mesh Grades: Mesh aperture sizes are tailored to application needs—common grades range from 10 µm through 1000 µm. Mesh wire diameters and counts are carefully selected to balance open-area (typically 20 % to 40 %) and mechanical strength.

• Finishes: After fabrication, cylinders undergo pickling to remove scale and contaminants, followed by passivation to restore the chromium-oxide layer. For sanitary or pharmaceutical uses, an additional electropolishing step ensures a smooth, mirror-like surface that resists fouling and simplifies cleaning.

Performance Characteristics

• High Burst and Collapse Ratings: Depending on mesh grade and support design, filter cylinders can withstand burst pressures exceeding 16 bar (232 psi) and collapse pressures up to 10 bar (145 psi).

• Temperature Tolerance: All-metal construction allows continuous operation from −196 °C (liquid nitrogen applications) up to 500 °C (steam filtration), with short excursions to 800 °C if necessary.

• Chemical Compatibility: 316L cylinders resist attack by acids, bases, solvents, and oxidizers. When combined with appropriate gasket materials, the filter cylinder assembly is compatible with a broad range of fluids, including corrosive process streams.

• Service Life and Cleanability: The rigid stainless steel structure endures repeated back-flushing, steam sterilization, and ultrasonic cleaning. Under normal operating conditions, service intervals can exceed 12 months before a thorough cleaning or inspection is required.

Applications

• Oil and Gas Industry: Filtration of hydraulic fluids, fuel polishing, and lube oil treatment. Filter cylinders trap particulate contaminants that can cause pump wear or engine failure.

• Chemical Processing: Catalyst support and recovery; separation of solids from liquid or gas streams in reactors and vent lines.

• Food and Beverage: Clarification of juices, syrups, and edible oils. Electropolished cylinders meet hygiene standards and prevent flavor transfer.

• Pharmaceutical and Biotechnology: Sterile vent filtration on fermenters and bioreactors; removal of particulates in buffer and media preparation.

• Water Treatment and Wastewater: Cartridge-style housings fitted with filter cylinders remove suspended solids, protecting downstream equipment and ensuring regulatory compliance.

Customization and Quality Assurance
Anping CREMOTIVE offers filter cylinders in diameters from 25 mm to 300 mm and lengths up to 2 m. Wire mesh grades, perforation patterns, core thicknesses, and end-cap styles are all configurable. Customers can request special features such as:

• Multiple Mesh Layers: Coarse outer mesh for debris deflection with finer inner mesh for final polishing.

• Segmented Spacing: Varying support rod spacing to optimize flow distribution and reduce fouling.

• Integrated Handles and Lifting Lugs: Facilitating safe handling and replacement in large filter vessels.

Comprehensive quality control includes:

• Dimensional Inspection: Laser micrometry ensures mesh thickness, outer diameter, and total length meet specifications.

• Burst and Collapse Testing: 100 % of batch samples undergo hydrostatic pressure tests to verify mechanical ratings.

• Surface Integrity Checks: Visual and microscopic inspections confirm passivation quality and absence of weld defects.

• Material Certification: Mill certificates documenting alloy composition, mechanical properties, and finish treatment accompany every shipment.

By combining robust construction, precise mesh fabrication, and rigorous testing, Anping CREMOTIVE Wire Mesh Products CO., LTD delivers stainless steel filter cylinders that integrate seamlessly into filtration systems—offering reliable performance, extended service life, and streamlined maintenance.
