Sintered Filters — Multi-Layer Series
SS316L Stainless Steel — Industrial Filtration
Product Overview
Sintered mesh filters are manufactured through high-temperature diffusion bonding compared to standard cylindrical filters, resulting in higher flow rates and longer service life. They are ideal for applications requiring precise filtration under harsh operating conditions such as high-pressure hydrocarbon processing and chemical processing.
Multiple layers of SS316L woven mesh are stacked and fused at high temperature through atomic diffusion — no binders, no welds — creating a single rigid element with precisely controlled pore distribution. All media, support layers, and structure are constructed from SS316L stainless steel and diffusion-bonded at high temperature for maximum structural integrity and consistent filtration performance across the full service life.

Product Advantages
Multiple SS316L mesh layers fused at the atomic level — no adhesives or welds — producing a single rigid element with exceptional mechanical strength and consistent filtration accuracy.
Each layer contributes to precise and consistent particle retention, reduces replacement frequency, and lowers overall operating costs.
Diffusion-bonded structure handles up to 50 bar differential pressure. Sintered mesh filters can be backwash cleaned and reused across many service cycles, reducing total cost of ownership significantly.
SS316L construction with operating range from -268℃ to +371℃. Compatible with acids, solvents, hydrocarbons, and industrial chemicals.
All our stainless steel filters undergo bubble point testing to verify pore size consistency and filtration accuracy — ensuring corrosion resistance and preventing contamination. Each unit is verified with up to 200-point surface cleanliness test per kit before packaging.

Technical Support
Sintered mesh filters handle differential pressures up to 50 bar due to their multi-layer diffusion-bonded structure. They are suitable for high-pressure hydrocarbon processing, chemical plants, and hydraulic systems where conventional filters would collapse.
Multiple layers of SS316L woven mesh are stacked and heated below melting point in a controlled atmosphere. Atoms diffuse across layer boundaries, fusing the structure into a single rigid element without any binder material. This gives sintered mesh its exceptional mechanical strength and consistent filtration accuracy.
Standard filtration ratings range from 1 um to 200 um. The multi-layer construction allows precise control of pore size distribution across the filter media depth. Sub-um ratings available for specialized applications.
SS316L sintered mesh filters are rated from -200C to +600C. Special alloys (Hastelloy, Titanium) extend temperature capability further for corrosive or extreme temperature environments.
Yes. Sintered mesh filters are designed for repeated cleaning and reuse. Backwash cleaning with compatible liquids or compressed air is recommended. For high-temperature applications, thermal regeneration may be applicable.
Every filter undergoes bubble point testing, dimensional inspection, and passivation treatment. Material certificates (MTR) and inspection reports are included. No minimum order quantity for prototype samples.
