Sintered Metal Powder Porous Filter Elements: Tubular and Disc Filters

Stainless Steel Filter Pipes

Hengmao offers two forms of sintered metal porous filter elements: tubular / pipe filters and disc screen filters. Metal porous cylindrical filters are available in diameters from 13.5 to 135mm, continuous lengths up to 1500mm, and with a full range of sinter bonded end caps including 222, 226, flanged, threaded, closed and finished. Used in melt processing of chemical fiber, petroleum, water treatment, chemical industry, electric power, pharmaceutics, machinery, metallurgy, ceramics, dispose of sewage, foodstuff and beverage, cosmetic etc. Filter media: Sintered metal porous powder.

Filter Media: Sintered Metal Porous Powder

Materials Applied:
1. stainless steel 304/304L/316/316L
2. Copper, brass
3. Monel wire, inconel
4. Titanium, special alloy steel hastelloy,etc. 

1.High mechanical strength with the ability to maintain a steady filter rating under high pressure
2.Easy to clean and repeated use
3.Good corrosion resistance, good heat resistance
4.Easy to fabricate
5.Long service life


Sintered powder porous filter cartridges are suitable for applications with high temperature and high differential pressure requirements. Although they are typically less permeable than the equivalent stainless steel sintered fibre product, they are extremely robust and suitable for use in the most demanding operating conditions.The Sintered Powder filter elements have wide range of materials, including stainless steel, titanium, nickel, bronze, Inconel, Monel and Hastelloy.

Industries Served:
1. Food and beverage industry.
2. Chemical and pharmaceutical industry (pharmaceutical products,plastic Recycling and Precision sieving of powders,etc.)
3. Petrochemical industry.
4. Water treatment system.
5. Aerospace industry.

Filter Media - Stainless Steel Sintered Porous Metal Powder

Sintered stainless steel powder is normally formed by compressing a controlled blend of metal particles into their “green” state and sintering them in a controlled atmosphere furnace into a rigid media. The resultant medium is typically between 2-3 mm thick, ungraded through its thickness and has a fairly tight pore size distribution. During the initial compression of the medium, the high pressures gives rise to a smooth surface finish and high density media with a maximum void volume of around 50% This lowvoidage and high thickness leads to low permeability.
