Filter Structure

Stainless Steel Sintered Mesh Filter, also called Metal Mesh Sintered Filter, Alloy Mesh Filter, Sintered Layer Filter, along with porous powder sintered filter element, fiberglass sintered filter element, and PP/PE sintered filter element, all belong to the broad category of sintered filter elements.

The sintering mesh filter usually has five layers of stainless steel woven wire mesh, including one protective layer, one filter layer, one separating layer, and two supporting layers. Can also add a skeleton layer according to the using conditions sometimes.

Special Features of Sintered Mesh Filter

The stainless steel sintered mesh filter cartridge as an advanced filter element, has many advantages compared to ordinary filter elements like fiberglass, paper and normal metal mesh material.

1. High Precision

The precision of the sintered metal mesh filter can be up to 1 micron, can intercept impurities such as particles and colloids effectively. Sintering mesh filter elements can filter the viscous liquid, and keep the mesh holes stable, has a uniform filtration performance.

2. High-Pressure Resistance

The compressive strength of sintered mesh filter elements reaches 30MPa, has an excellent mechanical strength. It can withstand the pressure impact, and the structure is not easy to deform, metal sinter filter has a great performance in high-pressure working conditions.

3. High Temperature Resistance

The seams and the end cover of the sintered mesh filter are used with a metal welding process, rather than adhesive bonding. The using temperature of stainless steel material can up to 600℃, and some other alloy materials can be much higher.

4. High Corrosion Resistance

Stainless steel has higher corrosion resistance compared with fiberglass or paper, and has a longer service life in strong acid and alkali environments.

5. Washed and Reused

The sintered mesh filter elements can be washed, like backwashing, ultrasonic cleaning or high-temperature roasting. And can keep a good filter performance after washing, thereby can be reused and have a long service life, and cost saving.

Different Kinds Of Connection Can Be Custom

Cleaning Methods of Sintered Mesh Filter

The stainless steel sintered filter elements require standardized cleaning and proper daily maintenance during regular use to extend their service life.

Physical Methods

► Backwashing--Use clean water or compressed air to flush out impurities from the pores and surface of the filter element by introducing it from the outlet end in the opposite direction. Suitable for removing surface particles, sediment, and dust-like impurities. The pressure is at a range of 0.3 - 0.6MPa, the flow rate should be large enough to produce a strong flushing effect, but not so large as to damage the filter element.

► Ultrasonic Cleaning--Place the filter element into an ultrasonic cleaning tank filled with cleaning solution. The high-frequency vibrations of the ultrasound will dislodge impurities from the surface and interior of the filter element. The ultrasonic frequency is typically between 20 and 80 kHz, and the cleaning time is generally 15 to 30 minutes. This method is suitable for cleaning fine particles, oil sludge, and gelatinous impurities from micropores.

► Mechanical Brushing--For filter elements with stubborn stains or large particulate impurities on their surface, you can gently brush the surface of the filter element with a soft brush after backwashing or ultrasonic cleaning. However, be careful not to apply too much force when brushing, as this may damage the filter element's mesh structure.

Chemical Methods

► Acid Cleaning--When the filter element surface contains metal oxides or scale-like impurities such as calcium and magnesium, acid cleaning can be used. Commonly used acid cleaning agents include hydrochloric acid, nitric acid, and citric acid. The acid is prepared into a solution of a certain concentration, and the filter element is immersed in the acid cleaning solution for a period of time, and then rinsed thoroughly with clean water.

► Alkaline cleaning--When the filter element is contaminated with oil or organic matter, alkaline cleaning is an effective cleaning method. Alkaline solutions such as sodium hydroxide or sodium carbonate can be used, typically at a concentration of 5% to 15%. The filter element is immersed in the alkaline solution and heated appropriately for 1 to 3 hours, and then rinsed with clean water until neutral.

► Surfactant cleaning--For organic contamination, cleaning can be combined with the use of surfactants or enzymes (high concentrations of citric acid can be used in the food and beverage industry).

High-temperature Roasting

When organic matter is severely carbonized, the residue can be removed by high-temperature baking. This method is suitable for high-temperature operating conditions and high-temperature resistant filter elements. The baking temperature is generally ≤450℃, followed by a period of heat preservation and then natural cooling. It should be noted that not all sintered mesh filter elements are suitable for this method; the suitability depends on the material.

FAQ

Q1: How do I choose the right filtration rating for a 316L sintered mesh filter cartridge?
A: The filtration rating should be selected according to the particle size that needs to be removed, fluid characteristics, flow rate, and required filtration efficiency. We can recommend a suitable filtration rating based on your application.

Q2: What is the difference between sintered mesh and ordinary woven wire mesh?
A: Sintered mesh is made by bonding multiple layers of metal mesh through a sintering process. It provides a more stable and rigid structure, better resistance to deformation, and improved cleanability compared with a single-layer woven mesh.

Q3: Can you manufacture a replacement filter based on our existing filter?
A: Yes. We can manufacture customized replacement sintered mesh filter cartridges based on samples, drawings, dimensions, filtration requirements, or the original filter model. This helps ensure compatibility with existing filtration equipment.

Q4: Can the filter structure be customized for different installation requirements?
A: Yes. We can customize end connections, support structures, flange or threaded configurations, sealing materials, handle designs, and other structural details according to the customer's equipment.

Q5: Is 316L suitable for corrosive filtration applications?
A: 316L stainless steel offers good corrosion resistance and is commonly selected for chemical, pharmaceutical, food-processing, marine, and other demanding industrial environments. Final material selection should be based on the specific fluid and operating conditions.

Q6: Can you provide samples before bulk production?
A: Yes. Sample production can be arranged for customized filter cartridges. Customers can verify dimensions, structure, filtration performance, and equipment compatibility before proceeding with larger orders.
