FAQ about Sintered Porous Metal Filter

These are some frequently asked questions regarding the sintered porous metallic filters. Continue reading for more information.

 

Q1. Why would you choose a sintered porous steel filter?

A: The use of sintered porous metal filters to separate liquid, gas and solid gases has been proven to be an efficient and effective alternative. It can be used in place of other separation methods that are sensitive to high temperatures, pressure spikes and corrosive environments. Sintered porous metal filters perform better than vane filters, plates, and frame filters. They are reliable, easy to clean, and last a long time.

 

Q2. What are sintered-metal powder filters?

A: Sintered metal dust filters are made by pressing metal powders in porous sheets or tubes, and then sintering at high temperatures. The combination of powder size, pressing, and sintering operations in Sintered metal powder filters determines pore size, distribution, strength, and permeability. ASTM E-128 is used to determine the pore size of Sintered Metal Powder Filters. Media class is the media classification. It refers to the average flow pores or the average pore size of the filter. Sintered metal powder filters can be purchased in the following classes: 0.1, 0.0.2, 0.5; 1, 2, 5, 10, 20, 40, 100; and 0.2, 0.5. Liquid filtration classes for media 0.2 to 20 range between 1.4 and 35 um absolute. Gas filtration grades range from 0.1 up to 100 um absolute.

Sintered metal filter elements made from sheet or tube are fully welded. Filter media is manufactured using a porous, stable matrix, exact bubble point specifications, tight tolerances, and uniform permeability. This ensures reliable filtration performance, backwash cleaning, and long operational life.

Q3. What design considerations should you make for the sintered porous filter made of metal?

A: Consider the following factors when selecting a sintered porous steel filter. Previous blog posts about filter design considerations were focused on specific applications such as fuel filters or hydraulic oil filters in the marine, aerospace, and defense industries. The following are important considerations when considering sintered metal filter design.

UPore Size- Also known by the micron rating (or the micron rating), the pore size is the size of the particles you wish to eliminate. A filter with a "absolute" rating greater than 5 microns means that 99 percent of particles larger than 5 microns will be blocked. A 5 micron "nominal rating" will permit a higher percentage of 5-micron particles through the filter, possibly as high as 60%.

UPressure drop – This is the pressure change that occurs when liquids or gases flow through the filter. It is important to determine the requirements of your application and then assign it to a supplier of porous metal filters.

UTemperature range is the temperature at which the filter can work. You must ensure that the metal alloy used for the filter can withstand this temperature.

UStrength-Sintered filters are a great choice for high strength applications. They can be used in either forward flow or reverse flow.

 

Q4.what’s the application of porous metal filters

A: Sintered metal filtration technology can improve any pressure-driven filtration process that has high operating costs and is subject to corrosive environments and high temperatures. It is suitable for use in oil refineries, chemical, petrochemical, semiconductor, and pharmaceutical production.

 

Q5. What materials are available for the sintered porous steel filter?

A: Bronze, stainless steel, and other alloys are all commonly available. For sintered filters, bronze is the most common and least expensive alloy metal. You may choose to use other metals or alloys for greater strength, corrosion resistance or higher temperatures. Another popular material is stainless steel, which has excellent heat and corrosion resistance. 316L stainless steel is the best.

Nickel alloys are sometimes required for extreme environments. There are three options: Inconel, Hastelloy, and Monel. Each of these alloys is more difficult to machine, and their base metal composition is more expensive.
