This document outlines the critical technical constraints for the 20 µm, 20 PPI 316L sintered filter plate. It includes cleaning protocols, operational limits, and failure mode mitigation strategies.
- Cleaning and Maintenance: Compatible cleaning methods include backblowing, backwashing, ultrasonic cleaning, and chemical cleaning with dilute acids, alkalis, oxidizing agents, surfactants, or enzymes, but incompatible chemicals must be avoided.
- Operational Constraints: Increase pressure gradually during operation and avoid impact, scratching, or concentrated tool pressure on the porous surface.
- Failure Mode Response: When filtration efficiency falls below 50%, initiate a validated backblowing or backwashing procedure to restore performance.
- Compatibility Requirements: Confirm media compatibility, working pressure (≤3 MPa), and operating temperature (≤500 °C) before use.
- Integration Capabilities: The self-supporting plate can be welded, bonded, or mechanically integrated into assemblies and is machinable for custom adjustments.
This guide describes the safe handling and operational procedures for the 316L stainless steel powder-sintered filter plate. Follow these steps to ensure optimal filtration performance and extend service life through proper cleaning and maintenance.
Required Equipment: Backblowing system, Backwashing system, Ultrasonic cleaner, Chemical cleaning agents
- Confirm compatibility
Confirm media compatibility and operating conditions, including working pressure and temperature, before installation. - Increase pressure gradually
Increase the system pressure gradually to the operating level to avoid damage to the porous structure. - Monitor filtration efficiency
Monitor filtration efficiency and initiate a validated backblowing or backwashing procedure when efficiency falls below 50%. - Select cleaning method
Select a compatible cleaning method based on the retained material and process medium, such as backblowing, backwashing, ultrasonic cleaning, or chemical cleaning. - Perform cleaning
Perform the selected cleaning procedure while avoiding impact, scratching, or concentrated tool pressure on the porous surface.
What is the maximum working pressure and normal use 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, which provides mechanical rigidity and self-supporting properties for compact assemblies. Confirm flow, media compatibility, and through-pore requirements before operation.
Can this Ø30 × 3 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the metallic porous body can be regenerated using backblowing, backwashing, ultrasonic cleaning, or suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. Avoid impact, scratching, concentrated tool pressure on the porous surface, and incompatible cleaning chemicals to maintain performance.
What is the relationship between the 20 PPI pore density and the 20 µm filtration rating on this filter plate?
The 20 PPI porous structure provides a nominal pore spacing of 1.27 mm with 30–45% porosity and a bulk density of 4.4–5.6 g/cm³, while the 20 µm filtration rating defines the particle retention size. The combination supports particle removal with low initial resistance and interconnected flow paths for gas or liquid permeability across the 3 mm thickness.
The 20 µm, 20 PPI 316L stainless steel powder-sintered filter plate offers a self-supporting, cleanable porous medium for microfiltration in compact assemblies, with 30–45% porosity and a 500 °C temperature limit, but requires careful pressure management and media compatibility confirmation.
Positive
- Reusable, cleanable metallic media: The self-supporting 316L construction can be regenerated by backblowing, backwashing, ultrasonic cleaning, or chemical cleaning, supporting repeated use in laboratory and process filtration.
- Low initial resistance with uniform pores: The 20 PPI porous structure with 1.27 mm nominal pore spacing and 30–45% porosity provides stable gas or liquid passage with low initial resistance, suitable for microfiltration tasks.
Trade-offs
- Operating pressure and temperature limits: Maximum working pressure is ≤3 MPa and normal use temperature is ≤500 °C; pressure must be increased gradually and rapid pressurization avoided to prevent damage.
- Requires pre-order compatibility confirmation: Flow, working pressure, temperature, media compatibility, and through-pore requirements must be confirmed before ordering; cleaning procedure depends on retained material and process medium.
