bedrijfsnieuws over How Stainless Steel Wire Mesh Filter Cartridges Are Made | Pullner Filter

Stainless steel wire mesh filter cartridges are commonly used in industrial liquid filtration, gas filtration, pre-filtration, oil filtration, water treatment, and chemical processing. Compared with disposable PP filter cartridges, stainless steel mesh filter cartridges have higher mechanical strength, better temperature resistance, and can often be cleaned and reused.

A typical stainless steel wire mesh filter cartridge looks simple from the outside. It is usually a cylindrical metal mesh tube with stainless steel end caps. In some designs, the end caps are polished to create a smooth surface and rounded edges. However, the production process behind this type of filter cartridge requires accurate material selection, forming, welding, surface treatment, and final inspection.

The first step is wire mesh preparation. The filter layer is made from woven stainless steel wire mesh, such as 80 mesh, 100 mesh, or 120 mesh. Common materials include 304 stainless steel and 316L stainless steel. The material should be selected according to the filtration medium, corrosion resistance requirement, operating temperature, and working environment.

After the mesh is prepared, the flat stainless steel mesh is rolled into a cylindrical shape. During this process, the roundness and straightness of the filter body are important. If the cylinder is not formed properly, it may affect installation, sealing, and flow distribution. The seam of the mesh cylinder is usually fixed by spot welding or argon arc welding to keep the structure stable.

The end caps are processed separately. In most stainless steel mesh filter cartridges, the end caps are made from stainless steel sheet by stamping or produced by machining according to the customer’s drawing. For higher-quality products, the end caps are polished after forming. A polished end cap gives the cartridge a cleaner appearance and also helps remove burrs from the edge.

The mesh cylinder and the end caps are then assembled by welding. TIG welding, also known as argon arc welding, is commonly used for stainless steel filter cartridges. The weld is usually located at the connection between the mesh tube and the end cap. A stable weld helps prevent bypass leakage and improves the strength of the filter cartridge during operation.

After welding, post-treatment is required. The weld area may be ground or polished to improve the surface finish. Pickling and passivation can also be applied to remove welding oxides and improve corrosion resistance. This step is especially important for filter cartridges used in water treatment, chemical liquids, food-related pre-filtration, or other corrosive environments.

Although the structure is not complicated, the quality of a stainless steel wire mesh filter cartridge depends on several details. The mesh material must match the required filtration rating. The cylinder must be properly formed. The end caps must fit the mesh tube correctly. The welding must be continuous and strong enough to prevent leakage or deformation.

Before shipment, the filter cartridge should be inspected carefully. Common inspection items include appearance, weld condition, overall length, outer diameter, inner diameter, end cap structure, mesh surface, roundness, and filtration rating. For customized stainless steel filter cartridges, the inspection should follow the drawing, sample, or technical requirements provided by the customer.

Stainless steel wire mesh filter cartridges are suitable for many industrial filtration applications where strength, durability, and cleanability are required. They are often used for coarse filtration, pre-filtration, circulating liquid filtration, cooling water filtration, oil filtration, and protection filtration before pumps, valves, membranes, or downstream equipment.

For applications with high temperature, high pressure, or strong mechanical impact, stainless steel mesh cartridges can be a better choice than ordinary plastic filter cartridges. They can also be selected when the customer needs a reusable metal filter element instead of a disposable filter cartridge.

Pullner provides customized stainless steel wire mesh filter cartridges based on customer drawings, samples, or working conditions. Available options include 304 stainless steel, 316L stainless steel, different mesh ratings, cylindrical mesh structure, welded end caps, polished surface treatment, and customized dimensions.

When selecting a stainless steel mesh filter cartridge, Pullner can help customers check the filtration medium, flow rate, filtration accuracy, temperature, pressure, installation size, sealing method, and cleaning requirements. This helps ensure that the final filter cartridge is suitable for the actual working conditions.
