Sintered porous metal powder filter cartridgesAdmin2023-03-31T16:57:18+08:00
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
fire flame arrester

Micron rating option for sintered porous metal powder filter cartridges
1 micron, 5 micron and 25 micron are popular for the sintered metal powder filter elements. Other micron rating below 100 micron can be customized. Due to the structural property and metal powder particle size limitation, micron rating larger than 100 micron is rare to see.

Material option for the sintered porous metal powder filter cartridges
316 (1.4401), 316L (1.4404) stainless steel are the among the standard material for sintered porous metal powder filter cartridges. Hastelloy C276 and C22 are also popular materials in recent year for harsh corrsive environment. Inconel 600 601 is good choice for high temperature application with resistance to 800 ℃ maximum.
