You need to tell us these parameter requirements when you order a sintered metal filter

Pressure drop - refers to the pressure loss, which occurs when a gas or liquid flows through a filter. It is always critical to determine what your particular application can allow and specify it to your filter manufacturer.

Temperature Range - It refers to how hot or cold the surrounding environment is where you are operating the filter.

Pressure Drop - It is important to ensure that you maintain fluid pressure in your application and prevent any possibility of pressure drop for best results.

Fine tolerance - It refers to the ability of the sintered metal filter to filter the fluid without having to react with the fluid.

Thermal Shock - Changes in temperature usually cause tension in the material.

Where are you ordering the sintered metal filter intended for application?

Chemical processing - It is most common in nuclear manufacturing because it has some of the best properties, including high temperature and corrosion resistance.

Food and Beverage - It is primarily used in food processing to extract important nutrients and juices. They do not react to food or beverages, making them ideal for this application.

Power Generation- Sintered metal filters help ensure the efficiency and effectiveness of power generation by filtering water from turbines.

Petroleum refining- Sintered metal filters allow you to effectively filter different fuels to the desired degree.

Gas production - The elements are suitable for gas production because they do not react with the gas and you can also use them in different environments.

FAQ About Sintered Porous Metal Filter

Differences and differences between sintered metal filters of different materials?

The most common include bronze, titanium, nickel-based alloys, stainless steel fiber tapes, and special alloy powders.

Bronze is usually an alloy consisting of copper, which contains approximately 12-12.5% tin in addition to other metals and non-metals.

It is arguably the most common and lowest cost alloy metal used for sintered filters.

The advantage of bronze as a sintered metal filter is that it offers higher strength, higher temperature applications and better corrosion resistance.

Stainless steel fibers, on the other hand, are steel alloys with a minimum chromium content of 10.5% by mass and a maximum carbon content of 1.2% by mass.

The advantage of this material for sintered metal filters is that it has a high corrosion resistance with better heat resistance, thus ensuring optimal results.

Titanium is a lustrous transition metal, silvery white in color, with low density and high strength, thus favoring sintered metal filters.

Nickel refers to a versatile element that can form alloys with most available metals.

Therefore, nickel alloys are alloys with nickel as the main element.

It is ideal for sintered metal filters that are particularly suitable for extreme environments.

Nickel alloys are characterized by high resistance and corrosion resistance at both ambient and high temperatures.

Sintered metal filter process?

It is made when the bonding of particles in powder form occurs.

This bonding occurs by diffusion at a temperature relatively below the melting point.

This is a process involving three main steps.

The first step is to obtain the metal in powder form.

This can be done by grinding, atomization or chemical decomposition.

At this stage, you can choose to combine this powder with another metal to form an alloy or use it as is.

This process is somewhat simple and does not allow for changes in the elements.

The second step is to pour the powder into a specific mold where you can easily shape the actual design of the filter.

The filter composition is formed at room temperature and high pressure.

Usually, the amount of pressure you need to apply depends on the particular type of metal you are using, as metals have different ductility.

Compaction of the metal powder is performed in a mold to form a solid filter.

After this happens, you have the option to continue and remove the screen that is in a solid state and place it in a furnace at a high temperature.

So the result is what is now called sintering.

The metal particles fuse during the sintering process without melting, resulting in a high strength, rigid and porous filter.

Can I use sintered metal filters with many types of oils?

Yes. Sintered metal filters are designed in such a way that they can filter a variety of oils and many other substances.

What happens when a sintered metal filter comes in contact with acidic materials?

Typically, sintered metal filters are chemically compatible and have excellent strength and stiffness to withstand exposure to acids and other adverse substances.

Therefore, you can be sure that your sintered metal filter will still be usable even after contact with acidic materials.

What types of chemicals can pass through a sintered metal filter without damaging the filter body?

All types of chemicals can move through this particular product without causing damage to it, because they are made with strong chemical resistant materials.

Is it possible for one of these sintered metal filters to melt due to high temperatures?

The likelihood of a sintered metal filter melting due to extreme heat is very close to zero.

The reason for this is that during the manufacturing process, metals tend to bond at temperatures well below their melting point.

Therefore, this certainly results in a robust sintered metal filter that can withstand high temperatures as well as a variety of harsh conditions.

Will sintered metal filters continue to work even under freezing conditions?

Definitely yes, as long as you can backwash it.

And most sintered metal filters are often produced by cold isostatic pressure, which makes it possible to have high porosity.

In addition, it improves its stability even under freezing conditions.

How do I clean a sintered filter?

The first thing to do when cleaning a sintered filter is to make sure that the differential pressure of the particular sintered metal filter is checked.

Therefore, the first step in cleaning this product is to place it in a nitrogen-protected oven and make sure that it is heated to 380°C and left for about two hours.

Ultrasonic cleaning can be considered an effective technique for cleaning sintered filter metals.

Simply place the filter in the ultrasonic machine and heat it for about 30 minutes.

In order to increase the efficiency of cleaning the porous parts of the filter, you need to make sure that you use a method that can reach the internal parts.

So this definitely requires a continuous flow of fluid to remove contaminants.

This is why you need to flow the fluid in the opposite direction to the direction in which the particles are stuck.

This is called backwashing.

Another method you can use to remove contaminants is by immersing the filter in the fluid separately.

When you do this, you allow the contaminants in the fluid to absorb the fluid, then allow it to drain for a few minutes, and then repeat the process.

However, you need to make sure that you take all the necessary precautions when cleaning sintered metal to prevent it from breaking down or disintegrating.

How do I handle and store sintered metal filters?

When cleaning, always ensure that you use the recommended substances to give you the best results.

You also need to make sure that you observe the ideal precautions to prevent the filter from disintegrating during the cleaning process.

In terms of storage, always store them in the right place where there are relatively few physical actions that could damage them.
