Porous metal filters use metal powder as raw material without adding adhesive. This material is produced with forming under isostatic cool pressing and sintering with high temperature vacuum. The size and distribution of the pores are adjusted by choosing the size and process parameters of metal powder particles.

Properties

● Shape stability, components with high strength (sufficient pressure strength up to 50bar)

● Good filtering precision (0.5μm)

● Sufficient thermal strength up to 900℃

● Corrosion resistance

● Good mechanical properties

● Defined permeability and particle retention

● Good back flushing performance

Forms of delivery

Porous metal filters can be produced as tube shape. Fittings can be bonded to the porous parts by welding or directly during sintering process. Common specifications of outer diameter have φ20, 25, 30, 40, 50, 60, 70, 80, 90, 100, 140mm, length from 100 mm to1500mm, more than 1500mm can be welded, special specifications can be customized.
