2.Working Principle of Stainless Steel Filter Cartridge

Generally, the stainless steel filter cartridge uses the principle of physical filtration. Physical filtration means removing physical impurities that contaminate the purity of water and other fluids. It includes the use of a filter which will block the further movement of the solid impurities when the fluid passes through. A filter cartridge is a type of filter that has the housing to protect it from physical damage and other external factors.

As you know filter cartridge, it is easy to understand what is stainless steel filter cartridge. The stainless steel filter cartridge is a filter made from steel material. It has many advantages, but the most important one is you can use it to clean impurities such as physical impurities and chemical impurities as well.

As we know, the filter cartridge may be from different types of materials, but the main material is polypropylene and stainless steel. If you compare the two materials you will find stainless steel has many advantages.

Even though the working principle of a stainless steel filter cartridge is similar to the other types of cartridges, however, due to the particularity of material, the products provided by good industrial stainless steel filter cartridge manufacturers can make customers more satisfied.

3. Applicable Field and Range of Stainless Steel Filter Cartridge

Generally speaking, a cartridge will block or trap the impurities in the fluid as the fluid flows. But the filter manufacturer produces different filters with different micron ratings for different applications. You should know exactly what filter you are going to choose. It is important to choose the right and proper filter. The stainless steel filter cartridge filters industrial fluids such as oil, syrup, liquor, sugary fluids, fruit juices, and alcoholic products. Because the stainless steel filter cartridge has a very small micron rating, so you can filter sediments such as yeast sediments, and bacterial sediments. However, filtering liquid at high temperature is also one of the widely used.

4. Design Parameters of Stainless Steel Filter Cartridge

The micron grade range of stainless steel filter cartridge includes:
I. 5 microns responsible for fine filtration
II. 10 microns responsible for medium filtration
III. 50 microns responsible for pre-filtration as it traps larger particles of the sediments

At the same time, the design of stainless steel filter can meet the application needs of some harsh environment industries.
I. Applications that involve fluids at very high temperatures
II. Applications that deal with chemicals that can react with polypropylene
III. Applications with flow fluids with very high pressure

Of course, in addition to accurately filtering the particles in the fluid, resistance to high pressure, high temperature and chemical corrosion is also a characteristic of stainless steel filter cartridge.

The stainless steel material can either be SS304, SS 316L or SS316. To increase the area of filtration, the elements can either be cylindrical or plain.

5. The Features of Stainless Steel Filter Cartridge

Since you knew what is stainless steel filter cartridge, you should take care of the features for your own application.

You can choose the stainless steel filter cartridge depending on your application. The stainless steel filter cartridge has different sizes and features. The different features and sizes allow it to perform different functions.

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

5.1 Design-Cylindrical or Pleated

Manufacturers have two designs of the stainless steel filter cartridge which can either be cylindrical or pleated. The difference between the two is basically on the mode of application for different industries and composition. You can choose the proper one that conforms to your devices.

It is widely known that the cylindrical design provides a sleeve of filter media in support of a central core. Apart from that, the cylindrical design has a sintered wire mesh with five layers sintered in a vacuum. The finest micron filters rating range from 3 to 300 microns. It has many advantages such as good permeability, high strength, high resistance, and durable of a longer life.

The pleated design of the stainless steel filter cartridge uses a pleated media in support of a central core. Therefore, it can provide twice the efficiency of the cylindrical stainless steel filter cartridge.

In terms of welding technology, both of the two designs rely on ultra-clean, modern plasma and TiG welding systems. This method will guarantee the integrity of the cartridge as it eliminates bypass risks. Besides, it can also eliminate the presence of the extractable matter that is available in any of the boding agents.

5.2 Material Type

As the name suggests, stainless steel is the main material for making stainless steel filter element, which is composed of a variety of different types of metals, which constitute a series of corrosion-resistant steel. It basically consists of 8% nickel, and customers can choose other high corrosion resistant alloys such as Inconel, Hastelloy and Monel according to their needs. According to atmospheric conditions, safilter's stainless steel components can be used at temperatures up to 540 ° C (1004 ° f), with intermittent peak values up to 650 ° C (1202 ° f), and resistant to most chemicals. Because of its durability, high temperature and high pressure, safilter is also the preferred material for many industrial products.

Generally, S304 or s316 stainless steel is the most commonly used material by manufacturers.

5.3 Length

The length of the stainless steel filter cartridge depends on which type of application you need to do. Besides, the length of the stainless steel filter cartridge will also depend on the area you are measuring.

The length of the stainless steel filter cartridge is in millimeters. Nominal length is the measure of the distance from the top of the cartridge to the bottom of the cartridge. It will depend on your application. If the filter cartridge is longer, the ideal system flow rate and appropriate pressure drop can be obtained.

5.4 Diameter (inner/outer)

The diameter of the stainless steel filter cartridge is the widest part of a circle. It involves 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 consist of the inner and outer.

The inner diameter is the distance between the widest parts of the hole in the stainless steel filter cartridge.  The smaller the inner diameter, the bigger the filter cartridge will cover a wider surface area. If you use different ways such as inches or centimeters to measure it, the size will vary different greatly.

The outer diameter is the diameter of the outer part of the stainless steel filter cartridge. You can measure it by measuring the widest part of the stainless steel filter cartridge in inches or centimeters.  The longer the outer diameter of the cartridge, the bigger is the cartridge. Therefore, it means that the cartridge has more space to filter the liquid. The shorter the diameter, the smaller is the surface area in the cartridge.

5.5 Micron Rating

Micron ratings are the representation of the overall size of openings between the pieces of the filter media. If the micron rating of a filter media is larger, the hole will be wider. It means 20 microns is wider than 10 microns. At the same, if the micron rating is large, impurities will pass through the filter.

Stainless steel filter cartridges have very small micron ratings so that they can trap more impurities. The stainless steel filter cartridge varies in terms of micron ratings and that depends on the application which you choose.

Industrial applications that require filter the smallest microorganisms will use the filter cartridges with the smallest micro ratings. The stainless steel filter cartridge will ensure purity when the fluids pass through.

5.7 Working Pressure and Temperature

You know the stainless steel filter cartridge usually work under great pressure and very high temperatures. All these conditions determine the type of material when manufacturers use in making the fiber.

Therefore, it is important for you to understand the industrial application where you will use the filter cartridge. Manufacturers use different materials to produce different types of stainless steel filter cartridge. They also can produce the filters within a given pressure and temperature.

In order to determine how strong the material should be, you have to specify the working pressure and temperature through experiment. While manufacturers will specify the working temperature and pressure when they produce the normal stainless steel filter cartridges. They will display the maximum temperature where you can operate the filter cartridge comfortably without damages. They will also show the maximum pressure where the filter cartridge can work well at the first time without hitches. At the same time, the experiment will also show the maximum pressure that the filter can work normally when it is installed for the first time. These tests will help you grade different types of stainless steel filter elements.

5.8 Construction Method

Generally speaking, they are two common construction methods for the stainless steel filter cartridge. There is an adhesive or welded joint method.

5.8.1 Welded Joint Method

By connecting two or more stainless steel filters together, a complete structure can be formed. According to the geometric shape and size, the different parts of the cartridge are welded, including the welded joint, which can be divided into five types: tee, butt, corner, lap and edge.

5.8.2 Adhesive Joint Method

This construction should use an adhesive to joining the different parts of the stainless steel filter cartridge. An adhesive can either be glue, mucilage, paste, and 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 for you to 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.

When doing adhesive joints you should follow the basic rules:
I. Small cleavage and peeling stress.
II. Shear stress should be greater than tension
III. The area of bonding should be as large as possible
IV. The layer of adhesive thickness should be uniform and on the minimal

You should guarantee a strong bond between the elements and put them together when you take the two methods. It should be very strong when the stainless steel works under high temperature and pressure.

To avoid any breakage or destruction, welding the joints is the best method of constructing the stainless steel filter cartridge. But you should pay attention to the methods you choose when you apply them into practice.

5.9 Effective Filtration Area

Effective Filtration Area is the area for the stainless steel filter cartridge to filter. You will find a wider or larger filtration area provides a bigger surface area for the filtration of the fluids. If the filtration areas are small, it will provide a small effective filtration for the fluid when passes through the stainless steel filter cartridge.

If you want a wide effective filtration area, you need to give pressure to control the flow rate. In case you want to order a custom stainless steel filter cartridge, please make sure the filtration area is wide enough. The wide filtration area will increase the effective filtration area and make the device more reliable.

5.10 End Type

Most of the stainless steel filter cartridges have double open ends where both ends are open. You will find some of them only have one open end, so you need to identify them as the single open end filter cartridge.

There are five main end types of the stainless steel filter cartridge as follows:

I. Double open end with the grommet type of seal
II. Single open end with the grommet type seal
III. Single open end with the male NPT connection

The end types vary in size according to the type of machine that you choose. Customers should order stainless steel filter elements of the right size to suit different applications.
