Stainless steel woven mesh is of great significance to industrial production. It is a type of wire mesh that is made of stainless steel wire, created by weaving the wire strands together.Stainless steel woven mesh is commonly used in industrial settings for filtration, separation, and reinforcement purposes, as well as in architectural and decorative applications. It is resistant to corrosion and can withstand high temperatures and harsh environments, making it a popular choice for many different industries:

• Chemical industry. It sieves resins, coatings, pharmaceuticals, paints, cosmetics, etc.
• Food industry. It sieves powdered sugar, salt, starch, milk powder, soy sauce, fruit juice, etc.
• Metallurgical & mining industry. It sieves various metal powders, alloy powders, lime, quartz sand, electromagnetic materials, refractory materials, etc.
• Pollution treatment industry. It filters waste oil, waste water, activated carbon, additives, etc.

All these industrial production processes require the use of stainless steel woven mesh. Therefore, woven mesh plays an important role in the process of industrial screening and sieving.

Dashang has been providing woven wire mesh services to numerous clients for over 10 years. And now we will introduce you to how we weave wire mesh that meets the requirements and guarantees screening efficiency. The method is mainly based on the regularity of the mesh opening in warp and in weft, depending on 3 parameters:

Select the wire diameter in the center of the standard tolerance

Regarding this tolerance, it must be considered that the warp wire will lose a little bit of its diameter (we have to reduce it when choosing the initial diameter, or by reducing the reed step). For example, to weave a 0.125 mm / 0.090 mm mesh, we reduce the initial warp wire diameter by 5%, so we need to set the warp diameter at 0.095 mm (which will become an initial diameter of 0.090 mm) with a reed step of 0.215 mm; however, set the initial warp diameter at 0.090 mm (which will become 0. mm) with a reed step of 0. mm.

Make the steel reed precisely

For woven mesh of more than 300 mesh, we choose imported Japanese or German steel reeds to weave to ensure uniform and consistent mesh opening.

Weave high regularity in weft wire

With the goal of making perfectly metal woven mesh, we adopt full numerical control weaving machine, which can ensure the accuracy of the mesh.

A good woven wire mesh requires advanced weaving equipment, high-quality raw materials, and weaving personnel with rich experience in weaving. Dashang specializes in the production of metal woven mesh, providing solutions for the filtration and screening industry.

If your company needs wire cloth products, you have an extraordinary range of options to choose from. That means you need a clear understanding of some important functional requirements in order to select the right wire cloth.

Here&#;s a closer look at 8 features to consider when purchasing wire cloth.

1. Temperature

Understanding temperature thresholds is especially important in high-temperature applications when a fireproof wire mesh is needed. Given woven wire mesh can be made of any malleable metal or alloy, you should choose the specific material that works for your processes. A sampling of some of the maximum operating temperatures includes:

Material Temperature (Fahrenheit) Stainless Steel, Type 304 1,500 Incoloy 1,600 Stainless Steel, Type 330 1,650 Inconel 1,800 Nichrome V 2,000 Nickel 2,700 Tungsten 5,000

2. Viscosity

For applications such as wastewater treatment, oil handling and other petrochemical filtration, viscosity is an important consideration. Thinner, less thick fluids flow through filters faster. For highly viscous material processing, you need to discuss which type and size of wire mesh are necessary to achieve optimal results. In many cases, viscosity is directly related to temperature.

3. Pressure drop requirements

As materials flow through a filter and contaminants are removed, the pressure drops. After being filtered, the pressure will be lower than before. The wire cloth you choose for your filter media plays a big role in determining the pressure drop rate. Ultimately, the pressure drop will reach a point where the filter needs to be changed. Efficient wire mesh solutions that meet your pressure drop requirements reduce costs and contamination risks.

4. Specific gravity

Tailoring your wire cloth specifications often depends on the use. For many manufacturing processes, wire cloth mesh baskets and sieves are used to measure and test the specific gravity of a filtered material. Commonly made of stainless steel or brass, these products need to be ordered to sync with your specific gravity testing needs.

5. Particulate matter size

Particulate size is a seemingly obvious consideration when choosing the right wire mesh. Knowing the size of retained particles helps inform the mesh count, opening size and wire diameter. Test sieves in particular should be purchased to meet the required standards for retained particulate matter sizes.

At Newark Wire, we recommend selecting a size slightly smaller than that required.

None of these components work in complete isolation. For example, different mesh products with the same particle retention rate can have very different flow rates and pressure drop rates. Working collectively with your wire cloth provider helps you identify the right product for your manufacturing needs.

6. Flow Rates

Flow rate, viscosity and pressure drop are highly interrelated. For processes that mandate a required flow rate, you&#;ll want to consider the Percentage of Open Area to help determine the right mesh product.

7. Contaminant Types

The types of contaminants will help determine the material to be used, wire diameter, wire mesh density, tolerance, opening size and weave type.

8. Corrosive Effects

While most wire cloths are susceptible to corrosion, there are materials such as titanium and alloys like Hastelloy, Inconel and Nichrome that can withstand more corrosive applications.

Bringing It All Together

How do these myriad and interconnected criteria come together to select the ideal wire cloth? It&#;s best done in partnership with a skilled wire mesh producer like Newark Wire.

A process engineer who decides to use wire cloth in a liquid system must coordinate pressure-drop requirements with liquid temperature, viscosity and specific gravity. The engineer must also integrate information on particulate matter size and flow rates, and consider the nature of the contaminants or corrosive environment to be encountered. Once the parameters are set, hundreds of standard cloths are available in the common metals. In most cases, the engineer will not need to custom design a cloth, and manufacturers are helpful with application and metallurgical assistance for specific problems.

In summary, when choosing wire cloth, consider:

• Key determinants including temperature, viscosity, pressure drop, specific gravity, particulate size, flow rates, contaminants and corrosive effects
• That many of the considerations are interrelated
• Working with an experienced wire cloth company like Newark Wire helps you select the right product
