Sintered metal powder filter elements are high-performance porous filtration components manufactured from metal powders (e.g., stainless steel, titanium, nickel, Hastelloy, etc.) via mold pressing and high-temperature sintering processes. During sintering, the metal powder particles form a firm metallurgical bond through diffusion, melting, recrystallization and other processes, resulting in a uniform, stable and controllable microporous structure.
Parameter Category | Specific Indicators | Remarks |
Material | 316L, 304L, 310S, Hastelloy, Inconel, Titanium & Titanium Alloys, etc. | Selected based on the corrosiveness of the filtration medium and operating temperature; 316L is the most commonly used stainless steel grade. |
Filtration Precision | Typically 0.5μm ~ 100μm | Common precisions: 1μm, 5μm, 10μm, 20μm, 50μm; calibrated by the particle size with 98% filtration efficiency. |
Porosity | 30% ~ 50% | Higher porosity ensures larger flux and lower pressure drop, but slightly reduces mechanical strength. |
Permeability | Provides flow rate data under specific pressure difference | Reflects the flow capacity of the filter element, directly related to porosity and pore size distribution. |
Mechanical Strength | Compressive Strength: 1~35 MPa; Tensile Strength: ＞100 MPa | High strength, capable of withstanding high pressure difference and frequent backwashing without deformation or damage. |
Operating Temperature | -200℃ ~ +600℃ (varies by material) | 316L stainless steel is suitable for -200℃ ~ 400℃ in most industrial scenarios. |
Dimensional Specifications | Outer Diameter: Φ20mm ~ Φ100mm; Length: 250mm, 500mm, 750mm, 1000mm, etc.; Interface Type: M20, M30, 222/226, Plain End, etc. | Customizable to meet specific equipment and application requirements. |
Permeability | Provides flow rate data under specific pressure difference | Reflects the flow capacity of the filter element, directly related to porosity and pore size distribution. |
