Our sintered porous tubes are made of AISI 316L stainless steel. They are made by isostatic compaction of powder in a flexible mould with the negative shape of the part, and then sintered. The pore size is adjusted by changing the compaction pressure and/or the particle size of the powder.
These filters are commonly used for dead-end microfiltration of gases at high temperature or pressure and of liquids in a cross-flow filtration regime. Connections of different geometries are often incorporated at the ends ( as BSP or NPT standards or to customer specifications ).
