Sintered metal filter elements, best alternative of non-metallic filter for tougher working conditions

01 Feb.,2024

 

Sintered metal filter elements can be manufactured with various sintered metal filter media, which often include: sintered wire mesh laminates, sintered metal fiber felt (random fiber) , sintered powder porous metal and even combination of these types.

Sintered wire mesh laminates are multi-layer of wire cloth calendered and diffusion bonded. It is the combination of wire cloth.

Sintered metal fiber felt is made of random metal fiber, with process of random laying and sintering. It is non-woven like porous in-depth filter media.

Sintered powder porous metal is one kind of filter product from powder metallurgy. Metal powders are filled in the mold, then pressed and sintered. It is porous solid metal with in-depth filtration property.

Characteristics of sintered metal filter elements

All these sintered metal filter media are good alternative of non-metallic filter media ( PP, paper, glass fiber, etc). Because they have great characteristics to suit for harsh working environment:

  • Fixed hole / pore size even under high pressure and temperature
  • Resistant to temperature up to 800 degree Celsius ( certain alloy and thread connection)
  • Washable and easy-to-clean
  • Reusable even after chemical cleaning or burning
  • Strong integrity and strength to withstand higher pressure and shock
  • Self support or all welded structure, no risk of failure of glue and adhesive

Forming type and material of sintered metal filter

Sintered metal filter media can be formed into many types of filter elements:

Metal materials for sintered metal filter media have many choices, from ordinary 316L to outstanding corrosion resistant Hastelloy C22. We have experience with handling various metal materials, and we are willing to explore and try new materials to fulfill your new requirements.
