Stainless Steel Strainers

Stainless Steel is the primary component of all industrial strainers.  They function simply, by allowing material to flow into a strainer, or basket, and pass through the stainless steel mesh.  All particles that are bigger than the screen are suspended from traveling outside of the basket. This helps manufactures control what particles enter their final products.  All screens are dependent upon on the strainer size, and material being strained, so there are a lot of different screen options available.

Many stainless steel strainers are designed with the highest quality of materials and are spot-welded to ensure maximum strength.  Depending on the industrial application, companies can even purchase screens that are double reinforced and spot welded on both the seams and end margins.  Often, stainless steel mesh is standard in all industrial strainers, but some can come in bronze, titanium, copper, or different alloys.  Along with material composition, screens can have a wide variety of perforation sizes and the thickness of the metal itself.  Perforations often range from 0.030 to 0.250, contingent upon metal thickness. If a company requires a strainer for extra fine sifting, reinforced screens with perforated wire mesh are highly suggested. 

Strainers can be installed with magnets to help provide protection from abrasive damage. Iron and steel present in fluids can cause a great deal of damage to mechanical devices.  The number of magnets in a strainer is also dependent upon the size of the strainer. For example, a strainer ranging from 8”-10” can hold 4 magnets, while a strainer that is 16”-18” inches can be equipped with up to 5 magnets.

You can select a screen that also has reinforcing bands.  Reinforcing bands add permanency and vigor to stainless steel screen mesh and baskets.  It is recommended to add reinforcing bands to strainers tasked with straining conditions that have higher than average pressure drops.

Several different screen options also allow you to change the net free area ration of your strainer.  There is a specialized formula to use in order to figure out which ratio is the proper fit for your system.  Formula is as follows

Selected a perforation of screen size base upon the needs of your industrial application.  The screen must be small enough to filter the undesired material that is attempting to push through the screen.  The next step is to multiply the total screen area by the percent of open screen. These results will show the open area of the screen. Lastly, you have to divide the results by the area inside of the pipe.

Frequently Asked Questions about Stainless Steel Strainers

Stainless steel strainers are some of the strongest strainers on the market, but if you do not get the right one then they won't work to their full capacity. Also, maintenance of these strainers is important because it will help them function and last.  Below we will be compiling a FAQ for the purchasing, use, maintenance, and functionality of stainless steel strainers.

Is there a difference between a filter and a strainer?

Both of these items serve the same purpose, which is to separate solids from liquids. They both do amazing jobs, but there is a difference between the two. When you are removing solids that are smaller than 40 μm, you will want too use a filter. This is so small that you would not be able to see the debris with the naked eye. For stuff that is larger, greater than 40 μm, strainers will be used. Knowing what you are filtering will help you to pick between a filter and a strainer.

When would you use a filter?

If you are working with suspended solids in liquids and/or gases, you will use a filter. The filters will be able to filter out the tiny metal shaving from the hydraulic piston that is housed inside a hydraulic oil power pack.

Why is it important for me to get a strainer?

One reason to acquire such a product is for safety of your expensive gear. Pumps, heat exchangers, flow meters, compressors, and valves are all subject to damage from foreign particles. Strainers will help to keep out dirt, seeds, salt, resins, and so much more.  Strainers and filters help the longevity of your machines.

Another reason to get these products is to do certain jobs. In certain cases, liquid must be free from of all particles so that it can meet specific requirements. An example of this would be an ethylene glycol process that cannot handle particles above 30 μm.

How can I care for my Strainer?

Usually, different strainers have different maintenance regiments, and so it is important to fully read up on the type of strainers you acquire. Out of the bunch, basket strainers are the easiest to clean and maintain. Quick open strainers are easy to use as well, and they require less cleaning than other strainers. Stainless steel screen mesh is durable and can handle multiple cleanings without breaking. Strainers must be cleaned periodically so that the can work to their full potential.
