The Ultimate Guide To Woven Wire Mesh Filters - W.S. Tyler

When designing and incorporating mesh filters, there are three elements to the mesh that your mesh supplier needs to know to ensure your filter works as intended. Wire diameter, opening size, and mesh count all play a role in the effectiveness of a mesh filer.

You will get efficient and thoughtful service from Dashang.

• W ire Diameter: The width of each
   wire used to weave the filter
• Opening size: The Space between any two wires
• Mesh count: The number of openings in an inch in any direction

When designing a mesh filter, a “good, better, best system is used. The “good” category illustrates when one of the three elements listed is provided. “Better” illustrates your ability to provide two elements, and “best” illustrates your ability to provide all three. 

So, let’s say you send the mesh supplier a quote request for 200 feet of filter cloth with a mesh count of 50 microns. While the mesh supplier can provide an adequate recommendation, the inquirer’s exact needs remain unknown.

NOTE: Designing a woven wire filter may require you to convert mesh count to micron rating and vice versa. Use the following chart as a tool to help you comminate the needs of your operation:

If you were to submit a request for a 60x60 mesh filter with a wire diameter of ., the mesh supplier would have enough information to identify the mesh count and wire diameter. In turn, the mesh supplier can also calculate the opening size.

To that end, if any two elements are provided, the third can be determined; however, for best results, you should have all three ready before reaching out to the mesh filter supplier.

Sample Request
Woven wire mesh filter are a big investment. To ensure you are satisfied and confident with bulk orders, you have the opportunity to request samples of both cut pieces and fabricated components.

To do so, you must reach out and provide the following information:

• Alloy
• Dimensions
• weave pattern
• layer configuration
• Quantity needed

Having said that, there are a few limitations to note. As quantity plays a significant role in the feasibility of a sample request, we will need to establish the resources and labor your request requires.

Typically, if a woven wire supplier doesn't have the capacity to produce the desired component or specification, your sample request will get turned down. Your request can also get turned down if the rest volume doesn't align with the amount of tooling and labor needed to produce the component.

When it comes to cost, the amount you can expect to pay depends of the form factor of the sample.

If you are simply looking for cut-to-size pieces to familiarize yourself with a particular specification, the price tag will be fairly inexpensive. Of course, the price will depend on the various parameters of the specification.

If you are looking to sample a custom component, however, the expected cost will spike significantly. This is due to the increased labor needed to set up the tooling and fabricate the component.

NOTE: The expected cost of a customized part will increase as the complexity of the part increases.

What To Do After You Receive Your Sample?

If after testing the requested sample you find the performance does not meet your expectations, you should set a meeting with the mesh supplier's engineering team. This will give you the opportunity to identify the reason where improvements can be made.

Maybe it's as simple as switching someihng like the weave pattern or alloy. Or maybe you discover that woven wire mesh isn't the answer.

Either way, it is critical that you sit down with the engineering team so you can coordinate your next steps.

Now, if you are satisfied with how the component turned out, you will want to establish how many finalized parts you will need. After you decide and determine whether you will need a purchase order or blanket order, the next step would be to request a quote.

Once you receive a quote, approve it, and submit a purchase or blanket order, production will start.

You can use one of the following avenues to request a quote:

For filters and strainers type Y, T, basket, duplex, temporary, etc. it is very important to select the mesh that must be properly incorporated into our process. Selecting an incorrect mesh can cause problems in the short- and medium-term process:

If the selected mesh is very fine, therefore, with a very small filtration range, we initially cause a greater pressure drop in the installation and on the other hand we can make the filter clog with less time, causing that its maintenance and cleaning becomes more usual than desired.

If, on the other hand, a mesh that is too thick is selected, the problems arising from the pressure drop and clogging will decrease, but it will be possible to let through unwanted solids of a size that is too large and that may cause problems in other equipment of the installation or in same process fluid, turning it into a low-quality fluid.

That is why a correct selection of the mesh size to be installed can avoid many problems. For this, the following factors must be considered:

Type of solids

It is important to know what type of solids we have in our process: sand, stones, oxide, product residues, etc. This will limit us to a range of mesh size in which to make the subsequent selection.

Distribution of the solids contained in the fluid

In addition to the size, it is important to know the distribution of the solids. The size of the solids that a fluid drags does not have a constant size, since due to several factors such as friction, oxidation, etc. they take on different shapes and sizes. Therefore, having a spectrum of size and concentration allows us to verify where we have a higher % concentration of solids and in which range we must focus, since the objective will be to eliminate the highest quantity possible.

Objective of our filtration equipment

Another important factor to consider is the function of our equipment:

• Protect the installation and its components from foreign objects/solids
• Purify the fluid that circulates through our process

If our objective is to protect equipment or the installation itself, we will select a higher filtration size (larger mesh size) since we do not need the fluid to be 100% clean, but we need to ensure that there are no important solids that can cause wear, friction, oxidation, etc. On the other hand, if what we want is to purify the fluid of our process, we will select a smaller filtration size (smaller mesh size) to be able to remove as many impurities as possible.

Evaluating these three points, we will be able to select which is the most suitable filtration mesh for our process without compromising it with high pressure drop, excessive maintenance or poor fluid quality.
