Application range

Petrochemical, oil field pipeline filtration; fuel filtration of refueling equipment and engineering machinery equipment; water treatment industry equipment filtration; pharmaceutical and food processing fields; can also be used for chemical liquid filtration. Applicable to pretreatment and post-treatment systems in industrial sectors such as electronics, petroleum, chemical, pharmaceutical, and food. Further purify water with low suspended impurities (less than 2~5mg/L). The stainless steel filter cartridge is a filter element made of 304 or 316 stainless steel wire mesh as the main material, and is made of stainless steel wire mesh woven with various mesh shapes to obtain the best performance filtration grade. Different structural types can be selected according to different application requirements, such as epoxy bonding structure, crimping structure, and fully welded structure. The stainless steel wire mesh filter element can also be easily cleaned by backwashing, ultrasonic or other non-abrasive cleaning methods, so that it can be fully restored to a reusable state.

What are the types of stainless steel filter elements?

According to the manufacturing process structure, it can be divided into:

1. Epoxy bonded structure

Stainless steel filter elements are manufactured using epoxy bonded construction technology to obtain competitive prices. Epoxy bonded elements provide sufficient strength for many high-pressure applications. Epoxy bonded structures are ideal for most fluid applications.

2. Crimped structure (for industrial process filter elements)

This is a type of clarifying filtration that is particularly suitable for industrial process filter elements. It is often used in batch applications. These filter elements are usually pleated or cylindrical (wrapped) with a lightweight core and support ring. Industrial process filter elements are made of stainless steel by using crimping and welding without the use of brazing or epoxy resin bonding, thus overcoming the temperature and compatibility limitations of cellulose or synthetic fiber filter elements.

3. All-welded structure

Metal mesh filter elements have all stainless steel components, including end caps, center tubes, and metal mesh. When used in filtration applications involving hazardous fluids, the cleanability of these elements can greatly reduce processing costs.

Stainless steel welded structure metal mesh elements are ideal for harsh environment applications with extreme environments, high pressures, and corrosive fluids. These elements eliminate the harmful effects of media migration and provide precise filtration control of particles larger than the micron rating. Elements can be easily cleaned to restore their service life through backwashing or other techniques.

The rugged components and welded construction of metal mesh filter elements make them ideal for many high-pressure applications. Elements designed for collapse pressure ratings are available. Applications involving extremely high temperature ranges, which would destroy traditional epoxy-constructed elements, are ideal for using metal mesh filter elements.

All welded metal mesh filter elements are annealed to minimize the possibility of element failure due to the combination of intergranular corrosion and high pressure.

How do stainless steel filter elements work?

For stainless steel woven wire mesh filter elements, the working principle is to retain all contaminants with a diameter larger than the mesh diameter, thus having an absolute rating.

Stainless steel filter elements manufactured with sintered metal fiber felt media are deep stainless steel filter elements that can intercept contaminant particles at a deep level as the fluid passes through the filter element.

Depending on the type of stainless steel filter element application, the contaminated fluid can form from the inside out or from the outside in.

Air filtration with stainless steel filter elements usually removes particulate pollutants by the following mechanisms:

Inertial impaction: Large, high-density particles are usually captured by inertial impaction, which causes the particles to separate from the airflow and collide with the fibers.

Interception: It can remove medium-sized particles that are too small to have inertia and therefore follow the path of the airflow. These pollutants are suspended in the airflow, and when the particle comes into contact with the fiber, it adheres to the medium and is captured.

Diffusion: The smallest particles are captured by diffusion. These tiny particles travel along irregular paths, similar to gas molecules. This is called Brownian motion. Random motion increases the probability of particles hitting and adhering to the surface of the medium.

Features of stainless steel filter elements? (Advantages)

High pressure difference

It is a filter element with high pressure resistance, which is usually used in high-pressure fluid filtration applications to protect the long-term operation of equipment in high-pressure pipelines.

High temperature resistance

Stainless steel materials are able to maintain operation at high temperatures for a long time. For other materials, deformation is easy to occur when working at high temperatures for a long time, but stainless steel filter elements still maintain stability.

Cleanable

The material is stainless steel, which is very easy to clean and reuse. Cleaning the equipment will involve removing impurities and reinstalling it for further operation. It allows the fluid to be backwashed, ensuring that there are no residual contaminant particles in the surface of the stainless steel filter element.

Long Life The pleated stainless steel filter element increases its filtration area, which can obtain longer replacement cycles and extend the service life of the filter element. The element also has a certain corrosion resistance and a longer service life. The corrosion resistance also makes it an ideal filter element for passing fluids without secondary contamination.

Customizable Sizes It has different sizes, which can be used in a wide range of industrial applications. Different sizes can easily adapt to different types of equipment. It also provides different seals or gasket accessories for different applications.

Stable Pore Size The filter media has a fixed pore structure that can block contaminant particles from returning to the clean fluid. The absolute rating of the pores will provide consistent, reliable fluid filtration and improve filtration efficiency.

Why choose stainless steel filter elements?

Harsh operating environments require strong structural materials to operate as required. Whether your application involves extreme environments such as high operating pressures and differential pressures, extreme temperatures, or fluids that require compatibility, structural materials are critical to ensure that the system is protected. Since stainless steel filter elements have their own material advantages, they are easy to customize the design to meet the required materials, strength, flow requirements, thickness, micron rating, and environment.

It is a filter element with extremely high compressive strength, so industries that use high-pressure fluid flow use stainless steel filter cartridges for filtration purposes.

Stainless steel materials are able to withstand high temperatures and remain operational for longer periods of time. Other materials tend to deform at high temperatures, but stainless steel filter cartridges remain stable.

Since the material is stainless steel, it becomes very easy to clean and use again. Cleaning the equipment will involve removing impurities and reinstalling it for further operation. Stainless steel materials generally do not leave any stains and do not require much cleaning. Provide a more economical option.

The mechanical strength of stainless steel filter elements is also high and can withstand high pressures. The mechanical strength can withstand high temperatures and high pressures, and will maintain its shape throughout the operation.

The pleated stainless steel filter element increases the filtering surface area of the media. Make it more durable and you can use it for a long time before replacing it.

It is available in different sizes and you can use it for a wide range of industrial applications. The different sizes can easily accommodate different sized mechanical equipment. It also offers different O-ring or gasket accessories for different applications.

It has a fixed pore structure that blocks the contamination particles from flowing back into the clean fluid. The absolute rating of the pores will provide consistent, reliable and repeatable fluid filtration. Since the material is stainless steel, the device is corrosion resistant and will last longer. The corrosion resistance also makes it a suitable filter element that does not contaminate the passing fluid.
