Stainless Steel Filter Cartridge: The Definitive FAQs Guide

What are the Main Applications of a Stainless Steel Filet cartridge?

Stainless steel filter cartridge

Stainless steel filter cartridge

Pressurized gases– for protecting the equipment from oil, water, dirt and other impurities in compressed air.

Water treatment– used for passing water on a large scale since stainless steel prevents elements such as rust, algae, chemicals, decaying sediments, and organic matter, among others.

Fluidized bed combustion – it is essential in eliminating impurities from the system given that the process involves chemical reactions and rapid heat transfer.

Gearbox and bearing oil lube filtration – helps in cleaning the oil or lubricants that might have contaminations as a result of abrasion from moving parts hence enhancing the efficiency of the system function.

Condensate water – helps in preventing iron from corrosion and removing it to enhance the movement and safety of the whole system.

Seal protection – it helps in eliminating the impurities, which may get to the rotating parts of the system.

Fluidized bed combustion–it helps in enhancing the efficiency of the system by eliminating impurities even if it works at high temperatures.

What Kind of Construction are Available for Stainless Steel Filter Cartridges?

There are two major types of construction for this type of filter cartridge which include the following;

  • Welded joint method – it is about joining two or more pieces of stainless steel filter according to geometry and dimension together to create a complete structure.
  • Adhesive joint construction – it involves joining different parts of stainless steel filter cartridge by using an adhesive substance.

Which Materials are used to Manufacture Filson Stainless Steel Filter Cartridge?

What is the Advantage and Disadvantage of Stainless Steel Filter Cartridge?

Different end configurations for stainless steel filter cartridge

Different end confirgurations for stainless steel filter cartride

Some of the advantages of stainless steel filter cartridge include the following;

  • One key advantage is that stainless steel filter cartridge has a very high tensile strength which is fundamental in boosting its high-pressure resistance.
  • Another advantage is that it allows for backflushing of fluids which helps in ensuring that there is no fluid remains in the filter.
  • Again, this device is always stable irrespective of extreme temperatures which often destroy such devices.
  • As a device made of stainless steel material, you can be certain that it will last longer given that this resistance prevents it from being contaminated with chemical fluids that pass through it.
  • It is also easy to clean, given that it is made of stainless steel materials hence enabling you to re-use it.
  • This device has a fixed pore structure that resists the unloading of impurities back to the clean fluid.
  • It also has a high mechanical strength which withstands pressure and high temperature and still maintains its shape throughout the operation.
  • This device is available in different sizes hence making it easy for you to use it for numerous types of industrial applications.
  • Again, it is durable due to its construction design as well as materials used, thus giving you value for your money.

On the contrary, stainless steel filter cartridge also has a few disadvantages such as;

  • It is costly to purchase, replace, and dispose of compared to ordinary filter cartridge materials.
  • The amount of dirt in this material is insufficient; hence, in some instances, it tend to limit the efficiency of the device.

What are the Available Types for Stainless Steel Filter Cartridges?

The types of this product are dependent majorly on the particular application, and they include the following;

  • Mesh filter – ideal for a wide range of applications, especially in the electroplating industry, oil industry, and filtrating fluids with strong alkali and acidic conditions.
  • Wedge wire filters – design takes the shape of a wedge and is ideal for various challenging filtering applications.
  • Sintered filter– this is suitable for filtering fluids that have heavy contaminants.

How much Pressure Can a Stainless Steel Filter Cartridge Handle?

The maximum pressure for a specific stainless steel filter cartridge depends on a wide range of elements including:

  • Application of the device
  • Particular type of stainless steel material used

In most instances, however, the manufacturer always tends to specify the maximum pressure that a specific device can handle.

What Temperature Extremes Can a Stainless Steel Filter Cartridge Handle?

Just like the working pressure, the extreme temperature that a stainless steel filter cartridge can handle is also dependent on the application as well as the particular material used form making it.

And the manufacturers will always specify the maximum temperature that the particular device can handle.

What is the Micron Rating and Mesh Size of Stainless Steel Filter Cartridge?

Micron rating refers to the representation of the overall size of openings which are between the pieces of filter material.

Mesh size, on the other hand, refers to the measurement of a particle often used to determine the particle-size distribution of a granular stainless steel filter cartridge material.

In general, the larger the micron rating of a stainless steel filter cartridge, the wider the holes.

How Many Gallons of Fluids Can your Stainless Steel Filter Cartridge Filter in One Minute?

Working of cartridge filter

Working of cartridge filter

Ordinarily, a high-quality stainless steel filter cartridge permits flow rates of up to 500 gallons per minute.

How do I Choose the Most Appropriate Stainless Steel Filter cartridge for my Filter Housing?

When Should I Replace and Clean Stainless Steel Filter Cartridge?

The best time to replace the stainless steel cartridge is once its efficacy level becomes relatively low.

You can as well change it when some of its parts are damaged.

On the other hand, the best time to clean this device is when impurities trapped from fluids clogs it.

How to Clean Stainless Steel Filter Cartridge?

Before embarking on cleaning this device, you ought to know the specific type of cleaning technique that you’ll use.

The most common cleaning techniques include;

  • Reverse cleaning
  • Ultrasonic cleaning
  • Chemical cleaning
  • High-temperature burnout

You also need to have a powerful cleaning agent as well as a highly effective water-based agent free from chloride ions.

So when cleaning, ensure that you check the differential pressure is low to avert accidents as a result of dismantling from occurring.

The second stage involves placing the device in a nitrogen protection furnace, then heating it to a temperature around 380°C for about two hours continuously.

Then remove the device and allow it to cool to the desired temperature the place it in ultrasonic cleaning slot of the machine that has a strong cleaning detergent.

This is where the cavitation of the filter and cleaning detergent easily penetrate the device from each corner.

All the dirt disappears once you take it through this particular process.

Then you can use water to rinse the cartridge to eliminate the residues.

After that, use a blow dry for about 20 seconds to dry out the moisture in the filters.

Alternatively, you can dry it at a temperature of about 50 degrees Celsius.

How can Back Flushing Efforts Work for a Stainless Steel Filter Cartridge?

Back flushing refers to the process of cleaning a filter cartridge that can be re-used due to its working condition.

It helps in pushing off the contaminants which have settled on the surface hence increasing the efficiency and durability of the cartridge.

How Long Can Your Average Stainless Steel Filter Cartridge Last For?

It will depend on how frequently you use the stainless steel filter.

Also, the type of fluid, temperature, type of material, pressure and contaminants will also determine the service lifespan of the stainless steel filter cartridge.

For example, you can replace swimming pool cartridge filter after 1 to 2 years. Assuming, they shall have served for about 2,000 hours.

How to Change Stainless Steel Filter Cartridges?

First of all, ensure that all the systems are shut down to prevent anything from coming through for filtration during the changing process.

While at it, you may choose to clean the joining parts or better still decide to replace them with the filter cartridge.

After that, you can now bring the new stainless steel filter cartridge and position it at the right point.

Also, note that the new cartridge filter has to be of the same size as the one you are replacing to fit easily into the system.

To prevent immediate and future accidents from occurring, ensure that you check and confirm everything is okay.
