Multilayer sintered mesh screens for vigorous chemical filtration

Sintered wire mesh screens are suitable for filter cartridges that need robust mesh resistant to vigorous chemicals. These screens are available in wide range of sizes to suit industry filter structures and also are made in specific sizes. The robust screens are made from stainless steel and special alloys.

Multilayer sintered mesh

Sintered screen multilayer mesh uses several layers of mesh to make a screen that offers high filtration efficiency with strength. Standard mesh structure comprises an external security layer, an internal main filter layer, drainage layer and eventually two strengthening layers to provide strength. All mesh layers are sintered to develop a single sheet of filter screen.

The sintered mesh screens can be fabricated in cylindrical or sheet formats and in a wide variety of lengths and diameters.

Cleaning

Reverse flow: It is used when most of the contaminants are larger in size as compare to pore size of the screen, reverse flowing the liquid or gas through the element will often be sufficient for cleaning. Generally a flow of minimum 2 times the forward flow offers adequate cleaning.

Ultrasonic cleaning: Surface contaminants can be eliminated by ultrasonic cleaning in a bath comprising detergent, deeply plunged particulate cannot be removed.

Chemical cleaning: Different types of chemicals such as acids, caustics, solvents are used to dissolve the contaminants or service fluids when they are hardened due to contact with air.

Sintered multilayer mesh screens are designed for high temperature applications of industries. The screens can be used for high temperature services up to 480oc. The standard combination of five layerssintered mesh made from stainless steel that is combined through sinter, compression and rolling and made into a type of porous material.

Applications of multilayer sintered mesh screen

Polymer filtration, cross flow filtration, gas filtration, analytical devices, medical equipments, aerosol applications, hot gas filtration, fuel and hydraulic oil filtration, RO pre filtration.

Heanjia offers a filtration solution with long experience in working with designers and end users to supply filtration products to industries like food, beverage, pharmaceuticals and chemical processing. We have developed a range of sintered mesh screens and elements designed to work in the most challenging conditions. We are able to offer a wide range of media that meet the demanding duties.

We can manufacture filter elements in a uniform high porosity filter medium. These elements offer long life and nominal maintenance cost. They provide high strength, good permeability filter medium with a tightly controlled pore size. The robust filter material made from sintered mesh is ideal to use for different types of filtration applications. These screens have a high surface area to provide good flow efficiency and dirt holding capacity.

Materials for sintered wire mesh include stainless steel, Hastelloy, Inconel and Monel. We also provide industrial standard format that easily fits many existing filter housings to perform at higher temperatures.
