Stainless Steel Filter Cartridge: The Complete Guide

Are you tired of using a filter cartridge that will require continuous maintenance every now and then?

Maybe, you are of the idea that there are very few filters that can help you work out your filtering issue.

Why don’t you take a tour into the world of stainless steel filter cartridges and see a huge difference?

https://youtu.be/Sty1Lo_ns6M

What is Stainless Steel Filter Cartridge?

A stainless steel filter cartridge in simple terms is a filter cartridge with stainless steel as the main material.

Stainless steel filter cartridge

The simple definition might be a little bit too short and might not drive the point home.

I will, therefore, break it down into simple parts and explain every component differently.

Physical filtration involves the removal of physical impurities that contaminate the purity of water and other fluids.

It involves the use of a filter which blocks further movement of the solid impurities as the fluid passes through.

A filter cartridge is a type of a filter that has a housing to protect it from physical damage and other external factors.

Working of filter cartridge – Source: Clean Pool and Spa

A stainless steel filter cartridge is a filter with a stainless material as the main material for the filter.

You can use a stainless steel filter cartridge to remove impurities such as physical impurities and chemical impurities as well.

The filter cartridge may be from different types of materials but the main material is polypropylene and stainless steel.

The working principle of a stainless steel filter cartridge is similar to the other types of cartridges.

Generally, a cartridge will block or trap the impurities in the fluid as the fluid flows through.

The filter manufacturer produces different filters with different micron rating for different applications.

The stainless steel filter cartridge filters industrial fluids such as oil, syrup, liquor, sugary fluids, fruit juices, and alcoholic products.

The stainless steel filter cartridge has very small micron ratings that can filter sediments such as yeast sediments, and bacterial sediments.

There are different designs of the product that is able to filter fluids at high temperatures with a lot of efficiencies.

The stainless steel is available in different micron ratings which include:

i. 5 microns for fine filtrations

ii. 10 microns responsible for medium filtrations

iii. 50 microns which are responsible for pre-filtration as it traps larger particles of the sediments.

The design of the filter is supposed to target certain industries that deal with applications that would destroy the polypropylene.

Such applications include:

i. Applications that involve fluids at very high temperatures

ii. Applications that deal with chemicals that can react with polypropylene

iii. Applications with fluids flowing at very high pressure

 Filter Cartridge

The stainless steel filter cartridge will offer resistance to the high pressure, temperature and corrosion of the chemicals.

The stainless steel material can either be SS 304, SS 316 L or SS 316.

To increase the area of filtration, the elements can either be cylindrical or plain.

The stainless steel filter cartridge possesses coarse filtration media that will ensure minimal damage to the main filtration media.

Manufacturers perform a bubble point test which ensures that all the pore openings are of similar size.

It does not allow migration off media and you can easily backwash and reuse the stainless steel filter cartridge.

Stainless Steel Filter Cartridge Features

The stainless steel filter cartridge is available in different features and sizes depending on the application.

The different features and designs of the stainless steel filter cartridge allow it to perform the different functions.

Some of the main features of the stainless steel filter cartridge are in the following paragraphs.

The features of the stainless steel filter cartridge assist in improving the quality of the device.

They are the components that make the device corrosion resistant, with very little maintenance for longer life.

Stainless steel filter

It, therefore, means that the features of the stainless steel increase the durability of the device.

· Design – Plain or Pleated

Manufacturers have two main designs of the stainless steel filter cartridge which can either be pleated or plain.

The difference in the two is basically on the mode of application for different industries and composition.

The plain design provides a sleeve of filter media in support of a central core.

Apart from that, the plain design has a sintered wire mesh with five layers sintered in a vacuum.

The filter ratings range from 0.5 to 200 microns making it among the finest micron filters.

It has very good permeability, easy to clean, high strength, resistance to corrosion and a guarantee to last longer.

The pleated design of the stainless steel filter cartridge will use a pleated media in support of a central core.

Stainless steel filter cartridge

It is, therefore, able to provide twice the efficiency of the cylindrical stainless steel filter cartridge.

The method of construction in both designs rely on the ultra-clean, modern plasma and TiG welding systems.

The construction method will guarantee the integrity of the cartridge as it eliminates bypass risks.

It also eliminates the presence of the extractables that is available in any of the bonding agents.

· Material type

The main material that many manufacturers use in making the stainless steel filter cartridge is stainless steel.

It is the material of choice in many of the devices because it is durable and able to withstand high temperature.

It is also an important material of choice due to the strength as it can withstand very high pressure.

Stainless steel is a combination of many different types of metal making up a wide range of steel resistant to corrosion.

It basically consists of 11% chromium, which you can change to add nickel, titanium, molybdenum, and niobium.

The addition of these substances will change the physical and chemical properties of steel this the name stainless steel.

The results of combining different types of metal give stainless steel of different grades.

Manufacturers choose to use the stainless steel 304 or 316 grade in making the filter cartridge.

Different designs of stainless steel cartridge filter

The general grades of stainless steel are in five main groups which include:

i. Ferritic stainless steels

ii. Austenitic stainless steel

iii. Martensitic stainless steel

iv. Duplex stainless steel

v. Precipitation hardening grades.

Specifications such as mechanical properties, grade composition, and production specifications are under the government of different national and international standards.

These classifications are the reasons why you find certain grade with the three code digit such as 304 and 316.

The three-digit code is the AISI numbering system which is still in use even though it is old.

Super Duplex stainless steel is a mixture of the ferrite and austenite in equal measures.

The resulting steel is superior to the features of the ferrite and the austenite steel.

The most significant difference is in the composition where super duplex steel has more chromium and molybdenum.

The high concentration of chromium and molybdenum makes the super duplex steel more resistant to corrosion than other duplex grades.

It is a material of choice because it is cost effective and reliable in chloride environments.

The other properties of the steel are the same with the other types of steel except it has cheaper alloys.

· Length

The length of the stainless steel filter cartridge varies depending on the type of application that you intend to do.

The length of the stainless steel filter cartridge will also depend on the area with which you are measuring.

The length of the stainless steel filter cartridge is in millimeters.

Technical drawing of cartridge filter – Photo courtesy: RB Filter

Nominal length is the measure of the distance from the top of the cartridge to the bottom of the cartridge.

It is usually given in centimeters or inches and it will vary according to the application.

The longer the filter cartridge the more the area available for filtration of the fluid passing through the filter.

· Diameter (inner/outer)

The diameter of the stainless steel filter cartridge is the measure of the widest part of a circle.

It involves measuring the line that passes directly through the center of the circle from one end to another.

There are two main diameters in a stainless steel filter cartridge which include the inner and outer diameter.

Stainless steel cartridge filter with different diameters

Outside diameter is the diameter of the outer part of the stainless steel filter cartridge.

You will measure it in inches or centimeters by measuring the widest part of the stainless steel filter cartridge.

The outside diameter also varies in different types of stainless steel filter cartridges.

The longer the outside diameter of the cartridge, the bigger the cartridge.

Therefore, it means that the cartridge has more surface area for filtering the liquid.

The smaller the diameter the smaller the surface area and the lesser the surface area.

Inside diameter is the distance between the widest part of the hole in the stainless steel filter cartridge.

The inner diameter is the space that the manufacturer leaves after installing the filter cartridge in its place.

You can determine the inner diameter in inches or centimeters but the sizes will vary greatly.

The smaller the inner diameter the bigger the filter cartridge as it covers a wider surface area.

It implies that the wider the surface area the smaller the filter cartridge as it does not cover more space.

· Micron rating

Micron ratings are the representation of the overall size of openings between the pieces of the filter media.

The larger the micron rating of a filter media, the wider the holes meaning 20 microns is wider than 5 microns.

On the same note, the wider the micron rating the more the impurities that will pass through the filter.

Stainless steel filter cartridges have very small micron ratings so that they can trap more impurities.

The smaller the micron rating, the higher the chances of trapping the small impurities that are available in a fluid.

Smaller micron rating of 0.2 to 2 microns is capable of trapping micro-organism such as bacteria.

Filter system

The stainless steel filter cartridge varies in terms of micron ratings and that depends on the application.

Industrial applications that require to filter the smallest of microorganisms will use the filter cartridges with the smallest micro ratings.

The stainless steel filter cartridge will ensure that the fluid that passes through it is pure.

· Sealing configuration

Before you decide on the final seal of the stainless steel filter cartridge, you should know the sealing configuration.

The sealing configuration will guide you in making the necessary measurements before complete sealing.

In many cases, the stainless steel filter cartridge goes through the heat or melting sealing system which is permanent.

In this case, the sealing configuration of the stainless steel filter cartridge should be very strong.

You should have a strong seal or high integrity that will not break under very high pressure and temperature.

It is a process that does not require compromise so it might be costly to achieve strength and beauty of the seal.

In this case, you will have to specify the width of the stainless steel filter cartridge before making the seal.

Stainless steel filter cartridge

It ensures the integrity of the seal and will help in avoiding any form of leakage of the filter.

Wider seals are more important and do not leak but require more force to make thus making it expensive.

· Working pressure and temperature

The stainless steel filter cartridges work under great pressure and very high temperatures.

These are the conditions that determine the type of material manufacturers use in making the fibre.

 Filtration process – Source: Machinery and Lubrication

It is therefore important to know the industrial application where you will use the filter cartridge.

Manufacturers make different types of stainless steel filter cartridges using different materials.

They also make the filters that can operate within a given temperature and pressure.

To determine how strong, the material should be, you have to specify the working pressure and temperature.

In the manufacture of normal stainless steel filter cartridges, manufacturers will specify the working temperature and pressure.

They will indicate the maximum temperature where you can operate the filter cartridge comfortably without damages.

They will also indicate the maximum pressure where the filter cartridge can work well without any hitches.

The stainless steel filter cartridges usually undergo a test to determine the conditions which they can work best.

These test will help the manufacturer in rating a particular type of stainless steel filter cartridge.

· Construction Method

Broadly the most common construction methods for stainless steel filter cartridge are the adhesive or welded joint method.

Welded joint method

It involves joining two or more pieces of the stainless steel filter together to make a complete structure.

It involves welding the different parts of the cartridge according to the geometry and dimension.

There are five main types of welding joints which include Tee, butt, corner, lap, and edge.

 Stainless steel sintered cartridge filter

Adhesive joint construction method

This construction involves joining the different parts of the stainless steel filter cartridge using an adhesive.

An adhesive can either be glue, mucilage, paste, among others for joining the parts strongly.

The strength of the adhesive bond will depend on the distribution and direction of the stress within the joints due to the load on it.

There are six main types of adhesive joints that you can choose.

They include butt joint, scarf joint, single lap joint, double lap joint, single strap joint and double strap joint.

The typical forces in adhesive joints are compression, tension, shear, bending involving compression plus tension and torsion.

The basic rules to consider when doing adhesive joints are:

i. Cleavage and peeling stress should be very small

ii. Shear stress should be more considerable than tension

iii. Make the area of bonding to be as large as possible

iv. The layer of adhesive thickness should be uniform and on the minimal

The two methods of construction should guarantee a strong bond between the elements put together.

It should be very strong as the stainless steel works under very high temperature and pressure.

To avoid any breakage or destruction, welding the joints is the best methods of constructing the stainless steel filter cartridge.

· Effective Filtration Area

Effective filtration area (EFA) is the area of the stainless steel filter cartridge that is available for the purpose of filtration.

A wider or larger filtration area provides a bigger surface area for the filtration of the fluids.

The small filtration areas provide very small effective filtration areas for the fluid that passes through the stainless steel filter cartridge.

 Effective filtration area

The rate of flow at a given pressure is also higher when the effective filtration area is wide.

This is the reason why we have the pleated stainless steel filter cartridge that has a wide surface area for filtration.

It provides more room for the fluid to flow through making the filtration area more effective.

In case you want to order for a custom stainless steel filter cartridge, make sure the filtration area is wide.

The wide filtration area will increase the effective filtration area by making the device more reliable.

Stainless steel filter cartridges require a more effective filtration area that is why most of them are big in size.

· End type

Most of the stainless steel filter cartridges have double open ends (DOE) where both ends are open.

There are some that have only one open end which you will identify as the single open end filter cartridge.

There are five main end types of the stainless steel filter cartridge as you are about to discover.

The five main end types of the stainless steel filter cartridges include:

i. Double open end with the grommet type of seal

ii. Single open end with a female NPT connection

iii. Single open end with the grommet type seal

iv. Single open end with the 222 O-ring

v. Single open end with the male NPT connection

End connection types

The end types vary in sizes according to the type of machine that you intend to use it on.

You will make an order for the stainless steel filter cartridge with the right sizes that will fit your machine.

How to Clean Stainless Steel Filter Cartridge

The stainless steel filter cartridge is one of the most durable devices industries use in the filtration of fluids.

The durability of the stainless steel filter cartridge depends on how you clean the device.

There is a wide range of stainless steel filter cartridges available and the cleaning methods may also vary.

In this guide, we will go through the process of cleaning the sintered stainless steel mesh filters.

You can use the process of cleaning the sintered stainless steel mesh in cleaning other types of filter cartridges.

The method of cleaning may, however, vary in some types of stainless steel filter cartridges.

The sintered stainless steel filter cartridge is available in three main forms which include:

i. Sintered mesh filter elements

ii. Sintered felt filter elements

iii. Sintered metal powder filter elements

It is the type of stainless steel filter cartridge that many industries use thus more suitable for cleaning demonstration.

Before cleaning, there are a few elements that you need to take care of and that includes safety.

Make sure you put on protective clothing and gloves to protect you from the dangerous chemical spills.

Apart from that, you need to prepare the following items that will assist you in cleaning:

i. Baking furnace filters on the excess impurities of grease in continuous temperature of 380 degrees centigrade.

ii. The NC ultrasonic machine for cleaning

iii. Spray equipment that you can easily adjust

iv. A cleaning tank where you can heat the filters.

A powerful cleaning agent and a highly efficient water base agent.

It should be free of chloride ions that might cause corrosion of the stainless steel.

The water for cleaning should be deep, and clean under the 5 millimicrons filtration equipment.

The chloride content of the water should be below 20mg per litre of water.

Gas that would assist in blowing the dust through the 5 millimicrons filtering equipment.

After securing all the cleaning equipment, the first step will be checking the differential pressure.

Make sure that the pressure is very low to avoid any accidents that may occur when you dismantle the cartridge.

You should also check the surface of the filter cartridge and ensure everything is okay before removing the filter cartridge.

Put the stainless steel filter cartridge in a nitrogen protection furnace and heat it to a temperature of 380 degrees.

The heating should continue for two hours as it filters out the dirt and the impurities sticking to the cartridge.

Remove the filter and allow it to cool to desired temperatures.

Place the filter in the ultrasonic cleaning slot of the cleaning machine.

The slot should have a strong liquid for cleaning inside and then heat it to 80 degrees for an hour.

In this part, the cavitation on the filter and the cleaning liquid will easily penetrate the filter from every corner.

The dirt will disappear gradually after taking it through these processes.

You can use the hanging piece method of detecting corrosion in the cleaning tank.

In case of any, you will use the cleaning agent to get rid of the corrosion conditions.

You can use the water to rinse the filter cartridge as much as possible to get rid of the residues.

After that blow the filters to dry the water from the cartridge for 20 seconds.

You can also dry the stainless steel wire mesh into the oven at a temperature of 50 degrees Celsius.

To check if there are any impurities on the stainless steel filter cartridge, you can use a magnifying glass.

The magnifying glass should be 30 times more powerful to help in the identification of any impurities.

If you find nothing, then the stainless steel filter cartridge is clean and should be reinstalled.

Replacing Stainless Steel Filter Cartridge

The purpose of a stainless steel filter cartridge is to trap impurities in the fluids that flow through them.

Continuous entrapment of the impurities will increase the burden on the filter cartridge and may slow the efficacy.

The relief to the clogging burden is to remove the stainless steel filter cartridge and clean it properly.

The process of clogging and cleaning can continue up to a point where you cannot clean it anymore.

This process of cleaning is possible but the cartridge may not be as effective as it should be.

The only option you have is to remove the old stainless steel filter cartridge and replace with a new one.

The incidents when you will have to replace the stainless steel filter cartridge are very few.

You will replace it after a long period of use and the efficacy is on a low level.

Apart from that, it is prone to damage and you will need to replace it when some parts are damaged.

The process of replacing the stainless steel filter cartridge is straight forward but you need to be careful.

Make sure that you have the protective gear on to avoid any injuries from the device or its contents.

Apart from that, you will need to gather all the tools that you need to assist you in replacing the cartridge.

Make sure you shut down the whole process so that nothing will come through for filtration during the replacement process.

Look at the pressure gauge and make sure that the pressure is at minimal or shut down completely.

Pressure gauge

Looking at the pressure system will also give you a clue that it is time to replace the filter cartridge.

Using the right appliances, such as a wrench carefully remove the stainless steel filter cartridge from the system.

After that check the adjacent joining parts of the system and see if they are in a good condition.

You can either clean the joining parts or replace them altogether with the filter cartridge.

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

The new stainless steel filter cartridge has to be of the same size as the one you are replacing.

It will make everything easy and they will fit into the system easily.

Make sure that the replacement is standard and the system is tight and in the right place.

Check that everything is in order to avoid any accidents that may occur in the future during the process of filtration.

Applications of the Stainless Steel Filter Cartridge

There are many applications where you will use the stainless steel filter cartridge in the filtration of fluids.

Most of the applications are industrial as they involve the high temperature and pressure systems.

You are about to know more about some of the major applications in the following guide.

a) Gearbox and bearing lube oil filtration

The systems in a vehicle’s gearbox require oil or lubricants to help in reducing friction on the moving parts.

The lubricants should be soft and clean to avoid any damages that impurities may cause to the gearbox.

The lubricants will reduce wear and tear in the gearbox thus reducing the aging of the system.

Gearbox

Apart from the gearbox of the vehicle, the lubricant is useful in other gearboxes in other industrial applications.

It is available in applications such as:

i. Industrial equipment gearboxes and turbine gearboxes

ii. Locomotive gearboxes and pinion gears

iii. Planetary gear drives, roller bearings, and reduction drives

The stainless steel filter cartridge is an integral part of these systems to help in cleaning the oil or lubricant.

The oil might have contaminations from abrasions on the moving parts which may be dangerous to the normal functions.

The filter will help in getting rid of the impurities making the system to be flawless in operation.

b) Fuel nozzle protection in oil burners

It is also important in the fuel nozzle protection of the oil burners and improves the efficiency of the system.

The oil burners are important especially in commercial, marine and industrial applications for heating of water.

In different industries, you will use the oil burners are responsible for heat generation, boiling water and generation of steam.

Oil burner nozzle

An oil burner is a type of mechanical device that will burn a liquid or a gas to flames under control.

The boilers need a fuel source which can either be oil or gas and converts the heat into steam.

Fuel comes from the storage tank and passes through the preheater and into the filter before going to the valve.

As the fuel goes through the filter, it undergoes a cleaning process that gets rid of the impurities.

The filter, in this case, is often the stainless steel filter cartridge which is able to operate in such conditions.

The impurities in the fuel may originate from any place including the original crude oil.

It is important to protect the fuel nozzles of the oil burners to maintain the efficiency of the boiler.

The contaminants in the fuel may alter the surface finish on the nozzle thus changing the spray pattern.

It may also alter the size of the nozzle thus changing the droplet size of the fuel and altering the entire system.

c) Fluidized bed combustion

Fuel particles are often in a suspension of hot bubbling fluidity beds of particulate materials and ash.

 Fluidized bed combustion

At this point, it receives hot gas air or oxygen that will assist in the gasification or combustion.

The whole process promotes chemical reactions and rapid transfer of heat within the bed of the combustion bed.

The system is very sensitive and any interruptions from impurities may alter the chemical process.

Normally, the stainless steel filter makes it more effective by eliminating the impurities from the system.

The system is fully functional even if it is working at very high temperatures and pressure.

d) Condensate water

The filtration of condensate water is one of the key points the system of the power plants.

A reliable and stable condensate water system is very important as it:

i. Protects the safe running of the steam and boiler turbine

ii. Extends the circle of resin regeneration

iii. Reduce the starting time of the system

Condensate water plant

In the operation of the whole unit, the main impurities in the system are iron and silicone.

The iron can corrode and affect the effective movement and safety of the whole system.

It can also melt and condense in the water at high temperatures so it is important to remove it.

e) Water treatment

Water is very important and can have contaminations by rust, dust, algae, decaying sediments, chemicals, and organic matter.

Wastewater treatment plant

To prevent the components from creating any problems with the health of the user, you will have to treat.

This possible by passing it through the stainless steel filtration cartridges in large scale ensuring the user are healthy.

f) Seal protection

The stainless steel filter cartridge is an important part of the industrial system and assists in protecting seals.

The seals of the industrial equipment are always rotating and any form of impurities may cause breakdown of the system.

The filter can, therefore, help by getting rid of the impurities that may reach the rotating parts of the system.

You can use it to protect the seals of the rotating equipment such as refiners and pumps.

g) Pressurized gases

The stainless steel filter cartridge protects the equipment from water, dirt, oil and other impurities in compressed air.

The filter is able to remove the impurities from the air effectively even under very high pressure with a 99.9% success rate.

Pressurized gas system

As the air passes through the filter, the impurities remain on the filter cartridge making the air that passes through clean.
