The filter plate must be operated within its rated temperature and pressure limits of ≤500 °C and ≤3 MPa. Pressure should be increased gradually, and cleaning methods must be selected based on the retained material to avoid damaging the porous structure.
- Gradual Pressure Increase: Increase pressure gradually to avoid damage to the porous structure.
- Efficiency Monitoring: If filtration efficiency falls below 50%, perform a validated backblowing or backwashing procedure.
- Mechanical Protection: Avoid impact, scratching, or concentrated tool pressure on the porous surface.
- Cleaning Selection: Select physical or chemical cleaning according to the retained material and process medium, using compatible options such as backwashing, backblowing, ultrasonic cleaning, or dilute acids/alkalis.
- Pre-Order Confirmation: Confirm filtration rating, PPI, disc dimensions, porosity, through-pore requirement, target flow, working pressure, temperature, and media compatibility before ordering.
Gradually pressurize the filter plate to the required operating pressure and monitor filtration efficiency. When efficiency drops below 50%, perform a validated backblowing or backwashing procedure and select appropriate cleaning methods based on the retained material.
Required Equipment: Backblowing equipment, Backwashing equipment, Ultrasonic cleaner
- Ensure Correct Flow Direction
Ensure flow direction is from the outside surface toward the clean side during installation. - Gradually Pressurize
Increase the operating pressure gradually to the required working pressure. - Monitor Efficiency
Monitor filtration efficiency during operation and if it falls below 50%, initiate a backblowing or backwashing procedure. - Protect Porous Surface
Avoid impact, scratching, or concentrated tool pressure on the porous surface during maintenance. - Select Cleaning Method
Select a compatible cleaning method such as backwashing, backblowing, ultrasonic cleaning, or chemical treatment based on the retained material.
What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 30 µm filtration rating?
The filter plate has a maximum working pressure of ≤3 MPa and a normal use temperature of ≤500 °C. These limits are specified for the Ø100 × 25 mm, 20 PPI, 316L powder-sintered construction, which maintains mechanical rigidity and structural integrity within these operating conditions.
Can this 30 µm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the metallic porous body is designed for repeat use and can be regenerated using backblowing, backwashing, ultrasonic cleaning, or suitable chemical cleaning procedures. Compatible chemical options include dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes, depending on the retained material and process medium. Avoid surface damage, rapid pressurization, and incompatible cleaning chemicals to maintain performance.
What are the key dimensional and structural specifications of the Ø100 × 25 mm 20 PPI filter plate?
The plate has a diameter of Ø100 mm and a thickness of 25 mm, with a pore density of 20 PPI, nominal pore spacing of 1.27 mm, porosity of 30–45%, and bulk density of 4.4–5.6 g/cm³. The material is 316L stainless steel powder with a density of 8.0 g/cm³, formed and sintered into a rigid, self-supporting microfiltration medium with uniform interconnected pores.
This 316L powder-sintered filter plate offers a 30 µm filtration rating with a 20 PPI interconnected pore network, providing stable gas/liquid permeability and low initial resistance in a Ø100 × 25 mm disc format. The self-supporting metallic construction supports welding, mechanical integration, and cleanable regeneration up to 500 °C and 3 MPa, making it suitable for demanding process filtration applications.
Positive
- Uniform interconnected pore network: Powder-sintered 316L structure provides stable 30–45% porosity and 1.27 mm nominal pore spacing, enabling consistent particle retention with low initial flow resistance across the plate.
- Regenerable and high-temperature capable: Metallic media can be cleaned via backblowing, backwashing, ultrasonic, or chemical methods, and supports normal operation up to 500 °C and 3 MPa, extending service life in process environments.
Trade-offs
- Pressure ramp and surface fragility: Pressure must be increased gradually; rapid pressurization, impact, scratching, or concentrated tool pressure can damage the porous surface, reducing filtration efficiency below 50% if not handled carefully.
- Through-pore rate must be confirmed: The through-pore rate is not fixed and must be verified against required flow and pressure conditions; actual permeability depends on the specific process medium and operating parameters.
