The filter plate must be used within a maximum working pressure of 3 MPa and a normal use temperature up to 500°C. The porous structure requires gradual pressure increase and periodic cleaning to maintain filtration efficiency above 50%.
- Pressure and Temperature Limits: Do not exceed 3 MPa working pressure or 500°C normal use temperature to avoid permanent deformation or material degradation.
- Pressure Ramp Requirement: Increase the applied pressure gradually during initial operation to prevent shock loading of the sintered structure.
- Filtration Efficiency Monitoring: Monitor the filtration efficiency and initiate a validated cleaning procedure when efficiency drops below 50% of the baseline.
- Cleaning Method Compatibility: Select cleaning methods based on the retained material, using options such as backblowing, backwashing, ultrasonic cleaning, or appropriate chemical agents.
- Pre-Installation Compatibility Check: Confirm the target flow rate, working pressure, temperature, media compatibility, and through-pore requirement before ordering or installing the plate.
Follow these steps to ensure proper operation and extend the service life of the sintered filter plate. The plate must be gradually pressurised and cleaned when efficiency declines.
- Confirm Compatibility
Confirm that the operating pressure, temperature, and media composition are within the specified limits before installation. - Gradually Increase Pressure
Increase the applied pressure gradually during initial operation to avoid mechanical shock to the porous structure. - Monitor Filtration Efficiency
Monitor the filtration efficiency regularly and prepare for cleaning when it falls below 50% of the initial value. - Select and Perform Cleaning
Select a compatible cleaning method from backblowing, backwashing, ultrasonic cleaning, or chemical cleaning based on the retained material.
What is the maximum working pressure and temperature for the 316L 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 Ø20 × 5 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the metallic porous body supports regeneration through backblowing, backwashing, ultrasonic cleaning, and suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The product notes that surface damage, rapid pressurization, and incompatible cleaning chemicals should be avoided to maintain reusability.
What is the pore structure and filtration mechanism of the 110 PPI powder-sintered filter plate?
The filter plate features a 110 PPI porous structure with 0.23 mm nominal pore spacing, 30–45% porosity, and a uniform interconnected flow-through pore network. The 20 µm filtration rating supports particle retention while maintaining gas or liquid permeability, with flow normally directed from the outside surface toward the clean side.
The 316L powder-sintered filter plate with a 20 µm filtration rating and 110 PPI porous structure offers a rigid, self-supporting metallic medium for compact filtration assemblies, combining low initial resistance with cleanability and weldability for repeated use in demanding process and laboratory applications up to 500 °C and 3 MPa.
Positive
- Precise 20 µm filtration with uniform pores: The sintered 316L structure provides a 20 µm filtration rating with a 110 PPI pore network (0.23 mm nominal spacing, 30–45% porosity), enabling consistent particle retention while maintaining low initial flow resistance across the Ø20 × 5 mm disc.
- Rigid, weldable, and cleanable construction: The self-supporting metallic body can be welded, bonded, or mechanically integrated, and supports regeneration via backblowing, backwashing, ultrasonic, or compatible chemical cleaning, extending service life in repeated-use applications.
- High-temperature and pressure capability: Rated for normal use up to 500 °C and maximum working pressure of 3 MPa, the plate is suitable for elevated-temperature gas or liquid filtration in petrochemical, pharmaceutical, and other process streams.
Trade-offs
- Requires pre-installation parameter confirmation: The through-pore rate, actual flow, working pressure, temperature, and media compatibility must be validated against the application before ordering; the stated ratings are nominal and not guaranteed across all operating conditions.
- Sensitive to rapid pressurization and mechanical damage: Pressure should be increased gradually; if filtration efficiency drops below 50%, cleaning is required, and the porous surface must be protected from impact, scratching, or concentrated tool pressure to avoid permanent damage.
- Cleaning protocol must match process compatibility: Cleaning agents and methods must be selected based on the retained material and process medium; incompatible chemicals or aggressive procedures can degrade the sintered structure, so a validated cleaning review is necessary.
