Woven stainless steel mesh is known for its precise mesh openings, high wear resistance, and strength. Its features include:

● Precise and uniform mesh openings

● High production consistency

● Durable and long-lasting

● Environmental

● Resistance to acid, alkali, and corrosion

 

For products with wide-ranging applications, differences in material and performance can significantly impact their effectiveness. Even products of the same type from the same manufacturer may vary in quality. To ensure optimal use, it is essential to understand all relevant product information, including material composition and performance characteristics.

As the following steps show how to select the suitable wire screen to various applications.

 

1. Define the Purpose of Filtration

First, identify the primary function of the metal wire mesh in the application:

● Particle Filtration: To remove particles (such as dust, impurities, or solid debris) from liquids or gases.

● Liquid Separation: To separate different liquids or suspended solids in a liquid.

● Gas Purification: To eliminate contaminants from air or industrial gases.

● Safety Protection: To prevent larger particles from entering equipment or pipelines and causing damage.

 

2. Understand the Characteristics of the Filtration Medium

Based on the substance to be filtered (liquid, gas, or solid particles), determine the following properties. Take stainless steel mesh, for example. Understanding its material and properties is crucial. If you’re unfamiliar with its properties, consider the following:

 

Physical Properties:

● Strength

Choose based on application requirements. For general strength needs, stainless steel like 304 is suitable, while 410 is ideal for high-strength applications.

● Hardness

Hardness affects wear resistance and machinability.

● Ductility and Formability

Grades like 304 and 316 have excellent ductility, making them suitable for stamping, drawing, and other forming processes. Austenitic stainless steels are preferred for applications requiring high plasticity.

● High-Temperature Resistance

Consider the heat resistance of stainless steel. For example, 310S performs exceptionally well in high-temperature environments, such as boilers and heat exchangers.

 

Chemical Properties:

● Corrosion Resistance

Select the appropriate grade based on the type of corrosive media:

304: Resistant to general corrosion, suitable for food processing and everyday environments.

316: With added molybdenum, it provides better resistance to chlorides and salts, ideal for marine or chemical applications.

2205 Duplex Stainless Steel: Performs well in environments requiring high corrosion resistance and strength, such as marine engineering.

● Acid and Alkali Resistance

Choose materials based on the concentration and temperature of the acid or alkali. For instance:

316L works well in acidic environments.

904L is suitable for strong acids like sulfuric and phosphoric acids.

● Oxidation Resistance

High chromium and nickel grades (e.g.310S) are better for oxidation resistance in high-temperature or humid environments.

 

3. Determine the Filtration Precision Standards

Mesh Count: Refers to the number of openings per inch of the mesh. A higher mesh count indicates finer filtration.

Particle Size:Measure or refer to the particle size (typically in microns). Select a wire mesh with matching pore size based on the medium’s characteristics.

Micron Rating: Represents the actual pore size of the mesh, measured in microns (μm).

4. Refer to Industry Application Requirements and Conduct Small-scale Testing

Different industries have specific filtration precision requirements. For example, Water Treatment typically requires filtration precision of 10-100 μm to remove suspended solids or particles.

Theoretical filtration properties may differ from actual performance. It is recommended to conduct small-scale testing. We will be pleasured to provide you with samples to conduct small-scale tests.
