Sintered porous metal powder is one kind of product from powder metallurgy. Metal powder, small metallic beads, is pressed in the mold by coaxial or isostatic means to form the shape. Then the shaped metal is sintered to become the sintered porous metal powder filter cartridge. The hardware / end fitting can be sintered with the metal powder filter body, without extra welding.

Characteristic of sintered porous metal powder filter cartridges

Sintered porous metal powder filter cartridges are characterized with:

  • robust structure with porous filtering path
  • self-support construction, easy to form cartridge and without any need of extra support
  • higher resistance to corrosion, due to the mass volume
  • in-depth filtration property
  • solid connection by sintering the hardware with the powder body, instead of welding

Application of sintered porous metal powder filter

Sintered porous metal powder filter can be in form of tube, cone and cartridge. They are widely applied in:

  • catalyst retention and recovery
  • air sparging
  • gas filtration
  • liquid filtration
  • fire flame arrester
