Product Introduction

Porous stainless steel filter capillary tube is a highly durable and efficient filter component made through a sintering process, commonly utilized in industries like filtration, chemical processing, and aerospace for its robust nature, thermal resilience, and exceptional filtration properties. These filters are crafted by compacting metal powder into specific shapes and subjecting them to high-temperature sintering, where the metal particles fuse together to form a solid structure with interconnecting pores of controlled dimensions. Employing Sintered Metal Powder Filter technology enhances the overall filtration efficiency of these products.

These porous stainless steel powder tubes, post-sintering, find application in liquid and gas filtration, gas/liquid flow control, and ventilation systems. In high-temperature settings, sintered stainless steel filter elements play a vital role in enhancing filtration processes and reducing operational costs. They are integral in various industries such as chemical processing, petroleum refineries, pharmaceutical manufacturing, and semiconductor fabrication.

2. Enhanced Surface Area: Capillary stainless steel filter tubes provide a larger surface area through their fine pore structure, improving filtration efficiency and volumetric processing capabilities.

3. Lower Pressure Drop: Due to the small channel size of capillary stainless steel filter tubes, fluid experiences lower resistance within the filter, resulting in reduced pressure drop, which helps lower energy consumption and enhance filtration system efficiency.

4. High Temperature Tolerance: Capillary stainless steel filter tubes can withstand high-temperature environments, making them suitable for applications requiring filtration under elevated temperatures without compromising filtration performance.

5. Chemical Stability: Stainless steel itself possesses excellent chemical stability, and capillary stainless steel filter tubes can withstand corrosion from various chemicals, making them suitable for applications requiring corrosion resistance.

6. Easy to Clean and Reusable: Capillary stainless steel filter tubes are easy to clean and maintain, and they can be reused multiple times without compromising filtration efficiency.

How are Sintered stainless steel Filters Made?

The manufacturing process of Sintered stainless steel Filters involves pressing stainless steel powder into custom molds with adequate pressure to ensure particle adhesion at contact points, facilitating easy ejection from the mold. Subsequently, the unsintered part, known as the "green" part, undergoes controlled heating or sintering in a carefully regulated atmosphere below the stainless steel's melting point. Shrinkage is accounted for during sintering, transforming the original powder particles into a fully connected, porous stainless steel filter structure. This meticulous control over the process dictates the micron rating of the filtration medium, with the sintered medium characterized by its porosity.
