Sintered Wire Mesh Material and Filter

Stainless Steel Sintered Wire Mesh Sheets and Filter Elements (1 to 200 Micron)

Sintered wire mesh is a porous filter material made by joining multiple layers of woven wire mesh. The layers are bonded together under high heat and vacuum using a diffusion bonding process. This process fuses the wires at every contact point without changing the opening size of the weave.

Compared to regular single-layer mesh, sintered mesh does not deform, shift, or drop wires under high pressure or dynamic flow. It combines precise filtration with high mechanical strength.

Production Process and Quality Control

★Production Workflow
Wire Mesh Inspection -> Layer Stacking -> Vacuum Sintering (above 1100 degrees C) -> Calendering -> Non-Destructive Testing -> Laser Cutting and Fabrication

★Testing Procedures

Bubble Point Test (ISO 4003): Verifies maximum pore size to ensure there are no oversize defects or cracks in the sintered layers.
Air and Liquid Permeability Test (ISO 4022): Measures pressure drop across the media at specific flow rates.
Weld Inspection: Liquid penetrant testing and pressure hold tests on all welded seams to prevent leakage.
Material Traceability: Material identification testing (PMI) on raw wire mesh; Mill Test Certificates (EN 10204 3.1) provided with every shipment.

OEM Customization Steps

How to order custom filter elements:

01/

Drawing Review: Send your 2D or 3D drawings (STEP, DWG, or PDF) with operating parameters (fluid type, temperature, working pressure, target flow rate).

02/

Sample Production: Sample making usually takes 7 to 10 working days.

Approval: You verify dimensions, flow rate, and bubble point test reports.

04/

Mass Production: Standard lead time for batch orders is 2 to 3 weeks.

FAQ

Q: Why choose sintered wire mesh instead of single-layer wire mesh?

A: Single-layer wire mesh easily distorts under pressure, which changes the filter rating and lets dirt pass through. Vacuum sintering fuses every wire intersection together. This locks the pore sizes in place, prevents wire movement, and allows the filter to handle backwashing and high pressure flows without damage.

Q: Can sintered stainless steel filters be cleaned and reused?

A: Yes. Sintered mesh filters can be cleaned using several methods based on the dirt type:
Mechanical Cleaning: High pressure backwashing, air pulsing, or ultrasonic cleaning.
Chemical Cleaning: Caustic soda, mild acid wash, or organic solvents safe for 316L steel.
Thermal Cleaning: Heat treatment to burn off polymer or organic residue.

Q: What is the difference between nominal rating and absolute rating?

A: Absolute Rating: The size of the largest rigid particle that will pass through the filter under standard test conditions (100 percent retention).
Nominal Rating: The pore size at which a specific percentage of particles (usually 85 percent to 95 percent) are trapped.
Sintered mesh has consistent pore distribution, making its nominal and absolute ratings very close.

Q: How do I select the right material for corrosive fluids?

A: Standard 316L stainless steel works well for water, oils, and mild chemical fluids. For aggressive environments, we offer special alloys:
Hastelloy C-276: For strong acids, hot chloride solutions, and oxidizing chemicals.
Inconel 600 or 625: For high temperature oxidation environments up to 900 degrees C.
904L or Duplex Stainless Steel: For saltwater, brine, and marine equipment.

Q: Will the filter layer break during the pleating process?

A: No. During pleating, the precise filter layer is protected by strong support layers on both sides. The sintered bond keeps the individual wires in place, preventing mesh damage or pore opening during bending.

Q: Do you supply quality certificates with shipments?

A: Yes. All shipments include EN 10204 3.1 Material Test Certificates. These documents cover raw material chemical analysis, thickness reports, and dimensional inspection results.
