stainless steel basket strainer

Stainless steel basket filters are pipeline filtration devices designed to remove solid particles from fluids, effectively protecting downstream equipment and ensuring smooth process flow. Below are its core features.

🔧 Working Principle and Structure

Stainless steel basket filters primarily rely on their internal filter basket (typically a basket-shaped or lift-type stainless steel mesh) to intercept solid impurities in the fluid. During operation, fluid enters through the inlet, passes through the filter basket, where particulate contaminants are trapped inside. Clean fluid then flows through the basket and exits via the outlet.

Its primary structure includes:

• Flange and Cylinder: Fluid passageway and containment space.
• Filter basket: Core component, typically made of stainless steel woven mesh, perforated plates, etc. Filtration precision can be selected as needed (e.g., 10-300 mesh, or higher precision 0.5-50 micron sintered mesh).
• Flange cover: Often designed as quick-opening for rapid access and cleaning of the filter basket.
• Drain Port: Located at the bottom or side for discharging accumulated impurities and flushing fluid.
• Sealing Ring: Ensures leak-free operation under pressure.
• Pressure Gauge/Air Vent (on select models): Monitors differential pressure and purges air.

🏭 Primary Application Fields

Stainless steel basket filters are widely adopted across numerous industries due to their corrosion resistance and broad applicability:

⚙️ Installation and Maintenance Key Points

Proper installation and regular maintenance are crucial for maintaining filter performance.

• Installation Notes:

  1. Typically requires horizontal installation. Follow the arrow indicators on the housing to ensure inlet/outlet alignment with fluid flow direction.
  2. Prioritize installation upstream of protected equipment (e.g., pumps, instruments, compressors), reserving sufficient operational space for future maintenance.
  3. When connecting flanges, use new gaskets and tighten bolts to specified torque to ensure reliable sealing.
  4. During initial startup or after cleaning, slowly open the inlet valve to allow fluid to gradually fill the filter, preventing sudden impact damage to the filter basket.

• Maintenance and Cleaning:

  1. Regular Cleaning: Shut down the unit to clean the filter basket when the differential pressure between inlet and outlet significantly increases (observable via pressure gauge) or upon reaching the scheduled cleaning interval.
  2. Procedure: Close inlet and outlet valves → Drain pressure to zero → Open quick-release cover or flange cover → Remove filter basket → Clean with water or compressed air (avoid scratching the mesh with hard objects) → Reinstall after confirming the basket is undamaged.
  3. Filter Basket Replacement: If the mesh shows severe deformation or damage, promptly replace the basket to prevent compromised filtration performance and downstream equipment safety.
  4. Seal Inspection: Regularly check seals for aging or deformation, replacing as necessary.

💡 Features and Advantages

The advantages of stainless steel basket filters are highlighted in:

• High dirt-holding capacity: The basket structure accommodates substantial impurities, extending cleaning intervals.
• Low pressure drop: Streamlined design and large filtration area minimize pressure loss during flow.
• Easy maintenance: Quick-opening design enables swift basket access and cleaning.
• High Corrosion Resistance: Stainless steel materials (such as 304, 316L, or even 2205 duplex steel) withstand diverse corrosive conditions.
• Continuous Operation: Especially with twin-chamber filters, valve switching enables cleaning without shutdown, ensuring uninterrupted process flow.
