Sintered Metal Powder Porous Filter Elements: Tubular and Disc Filters, available in SS and Titanium

Stainless Steel Filter Pipes

Hengmao offers two forms of sintered metal porous filters: 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.

A sintered powder filter is a type of filter element made from metal or non-metal powders that have been processed through a sintering technique. Sintering involves heating the powder particles to a temperature below their melting point, causing them to bond together due to diffusion, without fully melting. This process creates a porous but strong structure.

The resulting sintered powder filter offers a depth filtration mechanism, capturing contaminants throughout the thickness of the filter, not just on the surface. These filters are known for their precise and consistent pore sizes, high temperature resistance, and excellent mechanical strength.

Main Shape Types of Sintered Powder Filter:
Disc:

Shape: Circular and flat, resembling a disc.

Cylinder (or Tube):

Shape: Cylindrical, hollow in the center. Range from small tubes to larger cartridges.
This type of cylindrical filter is widely used in industrial processes for fluid and gas filtration. The hollow center allows for inside-to-outside or outside-to-inside flow configurations, depending on the setup. They can be used in backwashing systems and are ideal for applications requiring high flow rates and extended service intervals.

Sheet/Plate:

Shape: Flat and rectangular or square.
.
Sphere/Ball:

Shape: Spherical.
Used in specific applications where the flow dynamics and distribution are crucial.

Conical:

Shape: Cone-shaped.
Used in specialized filtration setups where flow distribution and direction are essential.

Why Sintered Powder Filter Elements? - Benefits over Sintered Mesh Filter Elements

Sintered powder porous filter cartridges are suitable for applications with high temperature and high differential pressure requirements.

Short comings and benefits compared with Sintered Mesh Filter Elements: Sintered metal powder filter cylinders are typically less permeable than the equivalent stainless steel sintered fibre product.
Benefits:
1, Sintered powder cylinder filters are extremely robust and suitable for use in the most demanding operating conditions;
2, Sintered Powder filter elements can be made of a wide range of materials, including stainless steel, titanium, nickel, bronze, Inconel, Monel and Hastelloy, to suit different uses;
3, Economic and simple structure: Sintered powder cylinder filter has simple structure and costs less.

Filter Media for SS Sintered Power Pipe Filter- 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.
