Sinter metal powder filters

Seamless sintered powder tubes (Sintered porous metal filter tube)

Sintered metal powder filter elements (porous metal filter) are ideal choice for process filtration applications where high strength and excellent corrosion and temperature resistance are required.
Manufactured from isostatically compacted and sintered metal powders ensure excellent powder uniformity and strength for superior filtration performance and long life.

Characteristics
1. Good shape stability
2. High mechanical strengthen and good integrity
3. Controllable pore sizes and porosity                                                                         
4. Good permeability
5. High corrosion and thermal shock resistance
6. Easy to be made into complicated shapes, can be put together by soldering or gluing
7. The service life can be prolonged by cleaning and regenerating process
8. A wide spectrum of precisely defined pore size distributions
