Classification Of Sintered Filter Tube
FiltEdge can provide you with a diverse range of sintered filter tubes that are compatible with your process technology solutions, facilitating secondary processing and system integration.
Stainless steel, titanium, nickel alloys, etc., excellent metal strength, pressure and high temperature resistance.
Sintered Plastic Filter TubePE/PP/PTFE and other materials, with no metal ion precipitation, light weight, high cost-effectiveness.
3D tortuous path, capable of achieving sub micron level deep filtration.
Mesh Sintered TubeMulti layer woven stainless steel mesh is sintered and fused, doubling its compressive and tensile strength, and having strong backwash recovery ability.
Fiber Felt Sintered TubeThe metal fibers are sintered using a 3D non-woven fabric method, which increases the pollutant holding capacity to three times that of ordinary sintered filter cartridges.
Features Of Sintered Filter Tube
FiltEdge’s sintered filter tube adopts high-precision hot melt sintering technology, which considers and designs the structure, flow field distribution, and secondary processing adaptability for you, allowing the sintered filter element you produce to operate stably under harsh working conditions.
Sintered filter tube supports seamless TIG/argon arc welding, laser welding, and turning processing. During welding, the molten pool is stable, does not burn through, and the edges are not blocked, reducing your processing failure rate.
There are no blind spots or boiling “big holes” in the entire pipeline. The fluid permeability is highly consistent, the Bubble Point is stable, and it can achieve excellent millisecond level air/liquid distribution effect for you.
Under high pressure differential conditions, the sintered structure remains stable, without deformation or rupture, and achieves zero medium detachment.
According to your working conditions, choose materials that are suitable and resistant to high temperatures, strong acids, strong alkalis, and organic solvents.
High porosity 3D microporous network with minimal fluid resistance. It can accommodate more impurities while reducing energy consumption for you.
Supports ultrasonic cleaning, chemical solvent rinsing, high-temperature burning or backwashing, with high flux recovery, significantly reducing your long-term consumable replacement costs.
The Quality Certification Of Sintered Filter Tube
FiltEdge will conduct Bubble Point Test, Permeability Test, and Material Inspection for each batch of sintered filter tubes according to ISO standards, providing you with high-quality materials, uniform pore size distribution, and pressure reduced sintered filter tubes. And provide you with FDA, PED, REACH certifications, etc. based on your market and usage.

The Application Of Sintered Filter Tube
FiltEdge’s sintered filter tube, with its excellent performance, can be used in industrial systems such as liquids, gases, and dust. After your secondary processing is completed, it can provide you with stable and efficient medium transmission and separation guarantee.
In high-temperature applications such as garbage incinerators, biomass power generation, blast furnace gas, and CEMS flue gas continuous monitoring systems, we intercept fly ash and particulate impurities to ensure the accuracy and emission compliance of subsequent analytical instruments.
The microporous structure of the Sintered filter tube enables the formation of uniform microbubbles in the gases of biopharmaceutical fermentation tanks, beer/beverage CO2 carbonation towers, and water treatment aeration tubes, ensuring efficient and stable fermentation and carbonation processes.
After secondary processing, the Sintered filter tube can be used in chemical powder fluidized beds, bin pump fluidized plates/tubes, and dense phase pneumatic conveying discharge nozzles to keep catalysts, resins, or powder particles in a “fluidized” suspension state, preventing agglomeration and blockage.
After processing the sintered filter tube into a sintered filter cartridge, its ability to be repeatedly cleaned and regenerated enables it to achieve the longest lasting use in petrochemical backwash filters, special single/double opening metal filter cartridge assemblies, and self-cleaning liquid filters.
Made of materials such as titanium, stainless steel, PTFE, etc., specially designed for harsh fluids such as strong acids, strong alkalis, and organic solvents.
Petrochemical hydrogenation reactor catalyst interception, high-purity electronic grade gas filtration. While reducing material loss, we can ensure the purity of the finished product for you.

There is a subordinate relationship between the two, and the sintered metal filter elements include sintered metal filter tubes, cartridges, discs, plates, sheets, etc. Apart from differences in shape and processing integrity, all other aspects such as precision, material, and craftsmanship can be achieved the same. It depends on your specific needs.
The most basic principle is that the pore size of the sintered filter tube should be smaller than the minimum size of the particles you need to filter. But it is also not advisable to choose high-precision ones to avoid frequent blockages. Here are some common application accuracies, or we can make specific choices for you based on your application.
Pharmaceutical/Fine Chemical : 0.2 µm-0.5 µm
Smoke continuous monitoring sampling probe: 0.5 µm-3 µm
Fermentation tank/beverage carbonation aeration (Sparging): 3 µm-10 µm
Petrochemical reactor catalyst recovery: 5 µm -20 µm
Fluidized bed/pneumatic conveying discharge pipe: 20 µm -50 µm
Viscous polymer/high-temperature heavy oil coarse filtration: 40 µm -100 µm
Of course, we can not only provide you with sintered filter tubes, but also offer you processed sintered filter cartridges. You only need to inform us of your working conditions, or provide your requirements directly, and our engineers can analyze, select, and customize processing for you.
