Sintered Stainless Steel Tube

Sintered stainless steel tubes have excellent mechanical strength and maintain their shape and structural integrity under pressure, ensuring consistent filtration performance.

Sintered Metal Filter Cartridge

Sintered Metal Filter Cartridge

In pharmaceutical and biotechnology applications, sintered metal filter cartridges can be sterilized through autoclaving or other methods to ensure the removal of bacteria and microorganisms from liquids and gases.

Sintered Filter Stainless Steel filter MSF036-4

Sintered Porous Stainless Steel Filters

Manufacturers can control the porosity during the production process, allowing for customization to meet specific filtration requirements. Higher porosity allows for greater flow rates but may reduce particle retention.

Sintered Filter Stainless Steel filter MSF041-4

Sintered Stainless

Sintered stainless filter offers excellent filtration efficiency due to its intricate pore structure. They can effectively remove contaminants, such as solids and particulates, from fluids and gases.

Sintered Filter Stainless Steel filter MSF039-4

Sintered Stainless Filter

Sintered stainless filters are made from finely powdered stainless steel particles that are compacted and heated (sintered) to form a porous structure.

Sintered Filter Stainless Steel filter MSF043-4

Sintered SS Filters

They find applications in a variety of industries, including pharmaceuticals, food and beverage, petrochemicals, water treatment, and automotive, where reliable filtration is essential for product quality and safety.

Manufacturing Details & Process

In fabricating stainless steel filters, filter pore size is essential. That is because the filter’s functionality relies on these factors. It helps determine the filter flow rate and pressure drop. 

Also, the powder particles and stainless steel density are significant elements in defining pore dimensions. These elements affect the pore distribution in filter finalization outcomes. 

Compression is among the additional procedures involved. It facilitates the attainment of the intended filter dimensions.

The next step is sintering, a process that improves their durability. After these procedures, sintered stainless steel filters are ready for structural or mechanical purposes.
