8 Things to Consider When Buying a Wire Screen
2019-10-08 By zhaozhao
If your company needs a Wedge Wire Screen product, you have a choice of options. This means you need to clearly understand some important functional requirements in order to choose the right wire cloth.
Below are the details of the eight functions to consider when purchasing a Wire Screen.
1. Temperature
Knowing the temperature threshold is especially important in high-temperature applications when a fire-resistant wire mesh is required. If the wire mesh can be made of any malleable metal or alloy, choose the specific material that is right for your process.
2. Viscosity
Viscosity is an important consideration for applications such as wastewater treatment, oil treatment, and other petrochemical filtration. Thinner, thinner fluids can flow through the filter faster. For high viscosity material processing, you need to discuss which wire type and size to achieve the best results. In many cases, viscosity is directly related to temperature.
3. Pressure drop requirements
As the material flows through the filter and removes contaminants, the pressure drops. After filtration, the pressure will be lower than before. The wire cloth you choose for the filter media plays an important role in determining the pressure drop rate. Eventually, the pressure drop will reach the point where the filter needs to be replaced. Efficient wire mesh solutions that meet your pressure drop requirements reduce cost and contamination risks.
4. Specific gravity
Tailored wire cloth specifications usually depend on the application. In many manufacturing processes, wire mesh screen baskets and screens are used to measure and test the specific gravity of the filter material. These products are usually made of stainless steel or brass and need to be ordered to meet your specific gravity testing needs.
5. Particle size
Particle size seems to be an obvious consideration when choosing the right screen. Knowing the size of the retained particles helps to understand the number of meshes, opening sizes and wire diameters. In particular, test sieves should be purchased to meet the required standard for retained particle size.
None of these components work in isolation. For example, different mesh products having the same particle retention can have very different flow rates and pressure drop rates. Working with your wire mesh supplier can help you determine the right product for your manufacturing needs.
6. Traffic
Flow rate, viscosity and pressure drop are highly correlated. For processes that require the required flow rate, you will need to consider the "open area percentage" to help determine the correct screen product.
7. Types of pollutants
The type of contaminant will help determine the material to be used, wire diameter, wire mesh density, tolerance, opening size, and weave type.
8. Corrosion
While most wire cloths are prone to corrosion, titanium, and alloys such as Hastelloy, Inconel and Nichrome can withstand greater corrosivity.
