What is a Sintered Metal Filter?
Goto JINTAI to know more.
A sintered metal filter is a filter engineered using the sintering technology. Sintered metal filters designed with perfect combination of metal membrane materials, pore structure, composition, and pressure strength last longer and filter consistently over the time. Variants of such filters offer compatibility and are designed for various harsh operation environments like high pressure, high temperature, corrosive chemicals, to name a few.
What is Sintering?
Sintering is a technology that fuses particles together by using heat and pressure without melting the metals. Various metals are sintered to engineer filter equipment, elements and different type of cartridges with a variety of pore size structure and composition.
Why Sintered Metal Filters?
Sintered metal filters are robust and exhibit excellent performance for separation of particulate matter from either liquid or gas process streams. The filter media is fabricated from metal power or fiber and sintered to form filter elements. These filter elements can withstand higher temperature as compared to other filter elements. Along with high temperature resistance, corrosion is also other criteria where sintered elements prove superior. Additionally, the cost of ownership of sintered filter systems is considerably low as they can be cleaned via &#;blowback cleaning&#; multiple times and reused with the same filtration efficiency.
The sintered filter systems and elements are critical in achieving effective particulate removal to protect equipment, meet environmental regulations and achieve successful cost-effective filtration operations.

It refers to the process of compressing and forming a solid mass of a particular material by pressure or heat without necessarily melting it to the liquefaction point or level.
It is the heat treatment that you apply to a powder compact to make it possible for it to impart strength and integrity.
Ordinarily, the temperature used for powder sintering is usually below the melting point of the key constituent of powder metallurgy material.
It refers to a component that is manufactured with a controlled level of porosity throughout the part to facilitate particular flow control housing, sound attenuation, venting, or filtering properties.
Sintered metal filter
The most common ones include bronze, titanium, nickel-based alloy, stainless steel fiber belt, and specially alloyed powders, among others.
Bronze is ordinarily an alloy that consists of copper which has about 12-12.5% tin, in addition to other metals and non-metals.
It is arguably the most common and also the lowest cost alloy metal that is used for sintered filters.
The advantage of bronze as a sintered metal filter is that it provides higher strength, higher temperature applications, and better corrosion resistance.
Stainless steel fiber, on the other hand, refers to steel alloy with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.
The advantage of this material for the sintered metal filter is that it has high resistance to corrosion, gives better heat resistance, and hence guaranteeing the best results.
Titanium refers to a lustrous transition metal that comes in silver, low density as well as high strength thus advantageous for the sintered metal filter.
Nickel refers to a somewhat versatile element that alloys with most of the metals available.
Nickel alloys are therefore alloys that have nickel as a principal element.
It is an ideal choice for sintered metal filter suitable especially for extreme environments.
Nickel alloys are characterized by their high electrical resistance and resistance corrosion at both normal and high temperatures.
Some of the main features of sintered metal filtration systems include:
The sintered metal filtration system
They include square, rectangle, triangle, circle, and polygon, among others.
It would also be important to understand that they come available in these shapes with microns from 1 to 200.
Types of sintered metal filters
It is made when the bonding of particles in powder form takes place.

This bonding takes place by diffusion in temperatures that are relatively below the melting point.
It is a process that involves three major steps.
The first step is about obtaining the powder form of your metal.
This can be done through grinding, atomization, or alternatively chemical decomposition.
At this stage, you can choose to combine this powder using another metal to form an alloy or use it as it is.
This process is somewhat simple and does not allow alteration of the element.
The second step is about pouring the powder into a die from where you can easily shape the actual design of your filter.
Formation of filter composition takes place under room temperature and high pressure.
Ordinarily, the amount of pressure that you need to apply is dependent on the specific type of metal you are using since metals have different malleable degrees.
Compacting of metal powder takes place to form a solid filter while in the die.
After this happens, you can choose to proceed and remove the screen, which is in a solid-state, and subject it to a furnace under high heat.
So the result is what is now referred to as sintering.
The metal particles fuse without melting during the sintering process hence forming a high strength, rigid and porous filter.
Pressure drop&#; Refers to the loss of pressure, which occurs as gases or liquids flow through the filter. It is always vital to determine what your specific application can allow and specify it to your filter manufacturer.
Temperature range&#;It refers to the level of hotness or coldness of the surrounding you are operating the filter.
Pressure drop &#; it is important to ensure that you maintain the pressure of the fluid in your application and preventing any possibilities of pressure drop for the best results.
Fine tolerance&#; it refers to the sintered metal filter&#;s ability to filter the fluid without necessarily reacting with it.
Thermal shock &#; it is the variation in temperature, which ordinarily causes tension in the material.
First, you need to understand that the accuracy of your measurement devices plays a significant role in determining the total surface area.
But essentially, the percentages of porosity and SS have to add to 100%.
For instance, if the porosity is 26% empty space, it thus means that the SS is 74%.
The volume of SS is therefore estimated by calculating the length of the fiber by the perimeter of the fiber.
The surface area of sintered metal filter
Chemical processing&#; mostly common in nuclear manufacturing, given that it possesses some of the best properties, including high temperature and corrosion resistance.
Food and beverage &#; it is majorly used for the extraction of vital nutrients and juices in food processing. They do not react to food or beverage, thus making them ideal for this application.
Power generation &#; sintered metal filters help in ensuring efficiency and effectiveness in power generation by allowing filtration of water in turbines.
Petroleum Refining &#; Sintered metal filters enable you to filter different fuels effectively depending on the degree levels which you require.
Gas production &#; this element is suitable for gas production since they don&#;t react with gases and you can as well use them in different environments.
Yes. Sintered metal filters are designed in a manner that makes it possible for them to filter a wide range of oils and many other substances.
Ordinarily, sintered metal filters have chemical compatibility and excellent strength and rigidity to endure exposure to acids and other unfavorable substances.
Therefore, you can be sure that you&#;ll still have your sintered metal filters even after they come in contact with acidic materials.
All types of chemicals can be moved through this particular product without harming it, given that they are made using strong chemical-resistant materials.
The chances of a sintered metal filter melting due to extreme heat are considerably close to zero.
The reason is that during the manufacturing process, the metals tend to bond at temperatures, which are way below the melting point.
So this definitely leads to a strong sintered metal filter that can withstand intense heat as well as a variety of harsh conditions.
Definitely yes as long as you can backwash it.
And the fact that most sintered metal filters tend to be produced by cold isostatic pressing, makes it possible for it to have high porosity.
Also, it improves its stability even in freezing conditions.
The first thing to do when cleaning sintered filter is to make sure that you check the differential pressure of the particular sintered metal filter.
So the first step when cleaning this product is by placing it in a nitrogen protection furnace and ensure you heat it to a temperature of 380°C and leave it there to stay for about two hours.
Ultrasonic cleaning is arguably the efficient technique of cleaning a sintered filter metal.
It is merely about placing the filter in the ultrasonic machine, and then you heat it for about 30 minutes.
And to enhance efficiency in cleaning the porous parts of the filter, you need to ensure that you use a method that will reach the interior parts.
So this definitely requires a continuous flow of liquid to remove the contaminants.
And that&#;s why you need to direct the fluid&#;s flow in the opposite direction from the direction the particles got stuck.
This is what is referred to as backwashing.
The other method you can use is removing the contaminants by dipping the filter severally in a fluid.
As you do this, you allow contaminant in the fluid to absorb the fluid then let it drain a few minutes then repeat the process severally.
Nevertheless, you need to ensure that you take all the necessary precautions when cleaning sintered metal to prevent it from breaking or disintegrating.
Packaged sintered metal filters
When cleaning, always ensure that you are using the recommended substances to make it possible for you to attain the best results.
At the same time, you also need to ensure that you observe the ideal precautions to prevent the filter from disintegrating during cleaning.
When it comes to storage, always store in the right places where there are relatively fewer physical actions that would possibly damage them.
Yes.
