This document defines the operational and cleaning constraints for the 316L powder-sintered filter plate. Adherence to these constraints preserves filtration performance and prevents mechanical or chemical damage to the porous structure.
- Pressure Application: Increase applied pressure gradually and avoid rapid pressurization to protect the sintered pore structure.
- Filtration Efficiency Threshold: If filtration efficiency falls below 50%, initiate a validated backblowing or backwashing procedure before further service.
- Surface Handling: Avoid impact, scratching, and concentrated tool pressure on the porous surface during handling and installation.
- Cleaning Compatibility: Select physical or chemical cleaning methods based on the retained material and process medium, using compatible backwashing, backblowing, ultrasonic, dilute acid, dilute alkali, oxidizing, surfactant, or enzyme options.
- Pre-Use Confirmation: Confirm working pressure, temperature, media compatibility, and through-pore requirements before putting the filter plate into service.
This procedure restores filtration performance after efficiency decline. Select a cleaning method that is compatible with the retained material and the sintered stainless steel structure.
Required Equipment: Clean-fluid backwash system, Clean-gas backblowing source, Ultrasonic cleaner, Chemical cleaning bath
- Inspect Filter Plate
Inspect the filter plate for visible surface damage or retained debris before cleaning. - Remove Coarse Contaminants
Remove coarse contaminants by backblowing with clean gas or backwashing with clean fluid in the reverse flow direction. - Apply Ultrasonic Cleaning
Place the plate in an ultrasonic bath with a cleaning solution compatible with the retained material and the sintered 316L structure. - Rinse Filter Plate
Rinse the plate with clean fluid to remove loosened contaminants and cleaning residues. - Dry Filter Plate
Allow the plate to dry completely before reinstalling it in the filtration assembly. - Confirm Performance
Confirm filtration performance after cleaning before returning the plate to service.
What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 20 µm filtration rating?
The filter plate has a normal use temperature of ≤500 °C and a maximum working pressure of ≤3 MPa. These limits are based on the 316L stainless steel powder-sintered construction with 30–45% porosity and 4.4–5.6 g/cm³ bulk density, as stated in the product specifications.
Can this Ø30 × 3 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the powder-sintered metallic media can be regenerated by compatible backblowing, backwashing, ultrasonic cleaning, or chemical cleaning using dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The product description explicitly states that the porous body supports repeat use when surface damage, rapid pressurization, and incompatible cleaning chemicals are avoided.
What is the relationship between the 20 µm filtration rating and the 110 PPI pore density in this filter plate?
The 20 µm filtration rating defines the particle retention size, while the 110 PPI porous structure provides a nominal pore spacing of 0.23 mm and 30–45% porosity. These parameters together support stable gas or liquid passage with low initial resistance, as the interconnected flow-through pore network enables particle retention without excessive pressure drop across the 3 mm thickness.
This Ø30 × 3 mm 316L powder-sintered filter plate delivers a 20 µm filtration rating with a 110 PPI interconnected pore network, supporting cleanable, reusable service up to 500 °C and 3 MPa, although it requires gradual pressurization and careful handling of the porous surface.
Positive
- Uniform 20 µm sintered pore network: The 110 PPI structure with 0.23 mm nominal pore spacing, 30–45% porosity, and interconnected flow paths supports stable gas or liquid passage with low initial resistance at a 20 µm filtration rating.
- Cleanable high-temperature 316L media: The rigid, self-supporting powder-sintered body can be regenerated by backblowing, backwashing, ultrasonic cleaning, or compatible chemical cleaning, and is rated for normal use up to 500 °C and 3 MPa working pressure.
Trade-offs
- Surface sensitive to impact and scratching: The porous surface must avoid impact, scratching, and concentrated tool pressure; only validated backblowing, backwashing, or compatible cleaning chemicals should be used to prevent mechanical and chemical damage.
- Requires gradual pressure ramp: Operating pressure must be increased gradually, as rapid pressurization compromises repeat use, and the maximum working pressure is limited to 3 MPa.
