Metal Porous Particles Sintered Filter Tube With Max Temperature 800C

Metal Porous Particles Sintered Filter Tube With Max Temperature 800C

These sintered porous metal filter elements are produced by cold isostatic pressing. For the compaction process the metal powder is filled into the compacting tool of combined steel and elastic material. By use of all around effective pressure build-up in a liquid, uniform porosity in the press part will be obtained and thereby homogeneous, physical characteristic properties will be guaranteed over the total part.

By this processing method the manufacture of seamless filter elements up to 1200 mm length and 320 mm diameter by differential wall thicknesses is possible. The isostatic pressing allows simultaneous compaction of flanges and threads. Thereby the mounting of such porous filter cartridges and filter tubes in the filter apparatus is very much simplified. A characteristic of the isostatic technique, as opposed to other manufacturing technologies is that smaller quantities can also be economically produced.

Materials of sintered porous metal filter elements

Corrosion Resistant Alloys sintered porous metal filter is available in a wide variety of corrosion resistant alloys including: Stainless Steel 316 L , 304L, 310, 347, and 430; Hastelloy B, B-2, C-22, C276, N and X; Inconel 600, 625, and 690; Monel 400; Nickel 200; Alloy 20; Titanium. High Temperature Capability Sintered porous metal offers a temperature range of 750 to 1750°F depending on alloy material and atmospheric conditions as indicated in Table 1. Temperature limitations of sintered porous metal in an oxidizing environment are not due to strength of material, but due to oxides which form at elevated temperatures. The specific void volume of the oxide is much greater than the parent metal, which results in plugging of the pores in the media. In a reducing or neutral Figure 1.
