Conical Stainless Steel Sintered Mesh Filter Element 140x490
PRODUCT DESCRIPTION
The conical stainless steel sintered mesh filter element is a custom‑engineered, high‑performance filtration solution designed for demanding applications requiring efficient contaminant removal with convenient cake discharge or continuous blow‑down capability. The conical shape is specifically engineered for applications where collected solids must be periodically discharged by backwashing, centrifugal slinging, or gravity, making it ideal for high‑viscosity polymer melts, heavy slurries, and high‑contamination industrial processes.
This kind of filter element is constructed from multi‑layer stainless steel sintered mesh – multiple layers of precision‑woven wire mesh that have been vacuum‑sintered into a rigid, monolithic structure. The sintering process fuses the wire intersections, creating uniform pore size distribution, exceptional mechanical strength, and resistance to deformation under high differential pressure and thermal cycling. Unlike simple woven mesh, the sintered structure will not unravel, shed fibers, or change pore size under pressure.

PRODUCT FEATURES
-
* Custom Micron Rating: Choose your absolute filtration rating from 1µm to 100µm+ to achieve the required fluid cleanliness level.
-
* Absolute Surface Filtration: Provides reliable, verifiable particle retention with a sharp separation boundary—no particles larger than the rated size pass through.
-
* Superior Durability: Withstands high temperatures, high pressures, thermal cycling, and corrosive environments.
-
* Fully Cleanable & Reusable: Designed for multiple cleaning cycles, offering exceptional long-term value and sustainability.
-
* Excellent Flow Characteristics: The multi-layer sintered structure provides high permeability with low pressure drop, maintaining system efficiency.
-
* Material Grade Options: 304 SS, 316L SS, 310s SS, Hastelloy, Inconel, or Titanium to match your fluid compatibility requirements.
- * Conical Geometry for Efficient Solids Discharge: The tapered shape allows accumulated contaminants to move toward the apex, where a blow‑down valve can continuously or periodically remove solids without stopping the process. Ideal for high‑contamination applications and continuous production lines.
Application
* Chemical Processing: Filtration of corrosive chemicals, acids, solvents, catalysts, and polymer melts. The all‑metal construction resists aggressive media while maintaining structural integrity under high pressure and temperature.
* Petroleum and Refining: High‑temperature gas filtration, catalyst recovery, slurry oil filtration, and fuel polishing. Sintered mesh withstands thermal cycling and pressure surges common in refinery operations.
* Hydraulic Systems: Fine filtration of hydraulic oil, lubricating oil, and fuel systems in industrial machinery. The rigid multi‑layer construction prevents collapse under high‑pressure differentials.
* Compressed Air and Pneumatic Systems: Particulate removal from compressed air lines, gas analyzers, sensor protection, and pneumatic valve filtration. External thread enables direct inline installation.
* Pharmaceutical Manufacturing: Sterile filtration of process gases, fermentation air, and high‑purity liquid streams. No fiber shedding ensures compliance with GMP and FDA requirements.
* Gas Distribution and Sampling: Pre‑filtration for gas chromatographs, process gas analyzers, and sampling ports. Removes particles and aerosols before they reach sensitive detectors.
MANUFACTURER OF SINTERED FILTER
At Huahang Filter, we combine deep material science knowledge with precision manufacturing to produce sintered metal components that meet the most demanding industrial requirements. Our 316L stainless steel sintered mesh elements are engineered to deliver consistent absolute-rated performance, structural integrity, and long service life in applications where failure is not an option.

* Precision Engineering for Guaranteed Fit: We meticulously manufacture to exact dimensional specifications, ensuring the sintered filter fits perfectly in designated housings. Our commitment to precision extends to end cap bonding, seal interfaces, and overall concentricity.
* Robust Construction for Demanding Environments: The diffusion-bonded monolithic structure provides exceptional mechanical strength, resistance to thermal cycling, and the ability to withstand high differential pressures without collapse or deformation.
* Comprehensive Customization Capability: Beyond standard sizes, we specialize in custom sintered components. Our engineering team can develop elements with specific micron ratings, dimensions, connection types, and material grades to meet unique application requirements.
* Rigorous Quality Assurance: Every element undergoes stringent quality checks.
2. Acid cleaning method
Dissolve potassium dichromate or crystals in water to 60 to 80 degrees, and slowly add concentrated sulfuric acid with a concentration of 94% until sufficient. Add slowly and stir. Add up to 1200 milliliters of potassium sulfate or completely dissolve, and the solution will appear dark red in color. At this time, the rate of adding concentrated sulfuric acid can be accelerated until it is completely added. If there are still undissolved crystals after adding concentrated sulfuric acid, they can be heated until dissolved. The function of cleaning solution is to remove general pollutants, grease, and metal particle impurities on the wall of stainless steel filter cartridge, and it can effectively kill the bacteria and microorganisms that grow on the filter cartridge and damage the heat source. If the filter element has been alkaline washed before, the alkaline solution must be washed first, otherwise fatty acids will precipitate and contaminate the filter element.

FAQ
Q: How do I provide my specifications for a custom order?
A: You can provide a drawing, sample, or simply a list of required dimensions, micron rating, material, and application details. Our engineering team will work with you to finalize the design and provide a quotation.
Q: What pressure and temperature limits should I specify for extreme conditions?
A: Standard SS316L construction handles 3 MPa differential pressure and 480°C continuous temperature. For higher differential pressure (up to 10‑20 MPa), we add internal perforated cores and extra reinforcing mesh layers. For temperatures above 500°C, switch to Inconel 600 or 625, which remains stable up to 800°C. Always state both your operating pressure and temperature when ordering so we can adjust the layer stack and material grade.
Q: What connection interfaces are available for the base and apex?
A: We can machine any interface:
* Base (larger end) : Flange with bolt holes, threaded collar (male/female), clamp connection, or custom.
* Apex (smaller end) : Blow‑down port with threaded plug, blank flange, or open for continuous discharge.
Provide a drawing of your housing interface – we will match it exactly.
Q: Can this element be cleaned and reused?
A: Yes, sintered mesh filters are designed for repeated cleaning and reuse. Methods include backflushing, ultrasonic cleaning, and chemical soaking. Proper cleaning can extend service life significantly, reducing long-term costs.
Q: Can you produce elements in other sizes and shapes?
A: Absolutely. We manufacture custom sintered mesh filters in any size, shape (discs, cylinders, cones, capsules), and configuration. Provide your specifications, and we will develop the optimal solution.
