Filters are composed of five layers of steel wire mesh, which are used for purification and filtration in petroleum refining industries. Normally, these filters are made of stainless steel such as SS304 L, SS316 L, SS904 L and other alloys. For this purpose, a number of steels meshes are stacked on top of each other and pressed. Then rivets, welds or bolts are used as a supporting frame. It should be noted that the filter meshes have different mesh size, mesh material and layout according to the intended use and goals. The use of these filters leads to an increase in the efficiency of filtration, an increase in the quality of the filter and an increase in the flow rate.
