FAQS ABOUT SINTERED METAL FILTERS

2020-05-25 By zhaozhao

If you’re reading this, you likely already know a thing or two about sintered metal filters, though you may not know exactly what you need for your unique application. Here at Fluid Conditioning Products (FCP), our goal is to assist customers in procuring precisely the right porous metal filter for their larger-scale manufacturing or other custom projects that require at least 100 units.


We are the sintered filter strainer manufacturer in China, we can custom the filter element as your requirement and export it all over the world.

Still, have questions about sintered metal filters? We designed this helpful FAQ to address some of our customers’ most common questions.


Q: WHAT SIZES OF SINTERED METAL FILTERS ARE AVAILABLE?

A: Sintered filters can be made as small as the head of a pin, and maximum size is only limited by the size of the equipment the manufacturer has available.It can be produced in sheets of various thicknesses that can be cut and shaped, too.


Q: CAN I BUY A STANDARD SINTERED METAL FILTER OFF THE SHELF?

A: Unfortunately, no. 


Q: WHAT ARE THE MATERIAL CHOICES FOR SINTERED FILTERS?

A: Titanium, stainless steel, and various alloys are common. (Need something specific? Just contact us!) Bronze is the most popular and lowest cost alloy metal used for sintered filters. Reasons you may need to choose another metal type or alloy may be for higher strength, better corrosion resistance, or higher temperature applications. Stainless steel, another popular material, provides excellent heat and corrosion resistance – 316L stainless steel gives the best result.


For even more extreme environments, a nickel alloy may be desirable. Choices include Monel, Hastelloy, and Inconel. It’s true that these alloys each carry a premium cost, which is due to them being harder to work with and their basic makeup of more expensive metals.

Q: WHAT ARE SOME OF THE DESIGN CONSIDERATIONS FOR SINTERED METAL FILTERS?

A: Consider desired particle retention, the flow rate through the filter, operating fluid, and more when choosing sintered metal filters. 

Pore size – Also known as the micron rating, pore size defines what size particles you want to keep out. If a filter is rated for 5 micron “absolute,” this means that 99% of all particles over 5 microns in size will be blocked. If you specify a 5 micron “nominal” rating, you are allowing a larger percentage of 5-micron particles to pass through, perhaps as high as 60%.

Pressure drop – This refers to the loss of pressure that occurs as liquids or gasses flow through the filter. You will have to determine what your specific application can allow and specify this to the filter manufacturer.

Temperature range – How hot or cold is the operating environment where your filter will be working. The metal alloy you choose for your filter must be able to tolerate it.

Strength – Sintered filters are an excellent choice where high strength is a requirement. Another advantage is that they provide the same level of strength in forward or reverse flow.


Q: WHAT INFORMATION WILL I NEED TO PROVIDE TO THE MANUFACTURER TO PLACE AN ORDER?

A: See the previous question about design considerations. You will need to understand your application thoroughly before you can order sintered metal filters. The following questions need to be answered before to manufacture your sintered filters:


What is the application? (Examples are: filtration, fluidization, gas dispersion in a liquid, silencing, oil or other liquid extraction from a gas, )

What will pass through the filter?

What are the corrosion problems?

What special operating conditions, such as temperature or pressure, are involved?

What contaminants might be encountered?

What dimensions, shape, and tolerance are required?

How many units are needed?

How is the filter to be mounted or supported?

What are the desirable rate of flow and the allowable pressure drop across the filter unit?

What is overall the system pressure?


Q: I STILL HAVE QUESTIONS, HOW CAN I GET IN TOUCH WITH FCP?
