Product Description
Our sintered powder metal filters are manufactured by high-temperature sintering of fine metal powders (stainless steel, titanium, nickel, copper), forming a uniform porous structure with porosity of 28%–50% and pore sizes from 4 to 160 μm. The interlaced pore network resists thermal shock, corrosion and mechanical stress, performing reliably in acids, alkalis and high-temperature gases up to 550°C. After repeated cleaning and backwashing, filtration efficiency recovers above 90%. These cartridges are widely used in polyester and polymer melt filtration across Asia, petrochemical and high-temperature gas systems in the Middle East, and corrosive liquid service in European and North American process plants.

Frequently Asked Questions
Q1: What materials are available for sintered metal powder filters?
Common materials include SS316L, titanium, nickel-based alloys, and bronze. SS316L is suitable for general corrosion-resistant applications; titanium offers excellent resistance to strong acids and chlorides; nickel alloys perform well in high-temperature, corrosive environments; bronze is typically used for air, water, and fuel filtration.
Q2: How is filtration accuracy defined? Do you provide bubble point testing?
Typical filtration ratings range from 0.5 to 100 microns. We define accuracy based on the absolute filtration rating, supported by bubble point test data to verify that no particles larger than the nominal pore size pass through. Bubble point tests can be arranged for each batch, with reports available upon request.
Q3: What are the permeability and pressure drop characteristics?
The uniform porous structure of sintered powder provides stable permeability. Pressure drop increases gradually with flow rate, making these filters suitable for precise liquid filtration, gas distribution, aeration, and fluidization applications. Actual performance depends on pore size, material, and medium viscosity.
Q4: Can you manufacture custom shapes and structures?
Yes. Beyond standard filter cartridges, we produce porous plates, tubes, discs, diffusers, spargers, and fluidized bed distributor plates. Dimensions such as outer diameter, length, wall thickness, and pore size can be customized according to technical drawings or samples.
Q5: What are the main advantages of your sintered powder filters?
Hebei hosts a mature powder metallurgy and metal fabrication base. Leveraging local expertise in material blending, compaction, and sintering, we deliver a wide range of models, fast lead times, and cost-effective solutions. This allows us to support customers who require consistent quality and reliable supply for critical filtration and gas handling processes.
