About Sintered Filtration

Stainless Steel Sintered Mesh & Fiber Felt — Built for the Toughest Filtration Environments

Sintered filters are manufactured through high-temperature diffusion bonding — a process that fuses multiple layers of stainless steel mesh or randomly oriented fibers into a single rigid, porous structure without any binder material. No adhesives. No melting point loss. No compromise on corrosion resistance.

This makes sintered filters the preferred choice for high-temperature chemical processing, hydrocarbon separation, steam filtration, and high-pressure hydraulic systems where conventional filters fail.

Sintered Mesh Filter

Sintered Mesh

Stainless Steel Sintered Mesh Filters

Multi-layer stainless steel wire mesh diffusion-bonded at high temperature into a single rigid structure. Uniform pore distribution, excellent mechanical strength, and consistent filtration accuracy throughout service life.

Sintered Fiber Felt

Sintered Felt

Sintered Fiber Felt Filters

Stainless steel fibers air-laid into a random orientation and then sintered into a porous felt matrix. High porosity, large dirt-holding capacity, and excellent air/gas permeability — ideal for high-temperature dust collection and steam filtration.

What is the maximum temperature for sintered mesh filters?

add

Standard SS316L sintered mesh rated to 400C. Special alloys (SS310, Hastelloy) extend to 600C. Sintered fiber felt also rated to 600C. Confirm with our team for your specific application conditions.

What is the difference between sintered mesh and sintered fiber felt?

add

Sintered mesh: multi-layer woven mesh diffusion-bonded, rigid structure, uniform pore size, best for precise liquid filtration under high pressure. Sintered fiber felt: random fiber matrix, higher porosity and dirt-holding capacity, best for gas/steam filtration and dust collection.

What pressure can sintered mesh filters handle?

add

Sintered mesh filters handle differential pressures up to 50 bar due to the multi-layer diffusion-bonded structure. Suitable for high-pressure hydrocarbon processing, chemical plants, and hydraulic systems where conventional filters would collapse.

What testing is included with sintered filters?

add

Every filter undergoes bubble point testing to verify pore size consistency, dimensional inspection against drawings, and passivation treatment. Material certificates (MTR) and inspection reports included. Optional pressure hold tests available on request.

How are sintered filters manufactured — what is diffusion bonding?

add

Diffusion bonding (sintering) heats stainless steel mesh layers or fibers below melting point in a controlled atmosphere. Atoms diffuse across layer boundaries, fusing the structure into a single rigid element without any binder material — only solid stainless steel.

What materials are available?

add

Standard: SS316L for most applications. Special alloys: Hastelloy, Titanium, SS310 for high-temperature or chloride-rich corrosive environments.

What is the sample lead time for custom sintered filters?

add

Initial samples: 48-72 hours after drawing confirmation for standard custom configurations. Complex geometries or new tooling: 5-7 days. No minimum order quantity for prototype samples.

Can sintered filters be cleaned and reused?

add

Yes. Backwash cleaning with compatible liquids or compressed air is recommended. For high-temperature applications, thermal regeneration may be applicable. Avoid harsh chemicals that could attack the stainless steel matrix.
