Maintaining the functionality of Woven wire mesh screens for long term
Wire mesh is created from the interwining of lustrous wire that has been merged and interweaved to produce consistent parallel spaces with symmetrical gaps. There are different materials used to produce wire mesh, the major materials are usually from metals such as copper, aluminum, nickel, stainless steel etc.
The major applications of wire mesh include separating, screening, structuring and shielding. The application sectors of wire mesh include agriculture, transportation and mining sectors. Wire mesh is made for the transport of bulk products and powders for their high strength and durability.
Filtration mesh is a versatile product, this is particularly true because it is available in both woven and perforated and expanded metal. The screen mesh yields supreme quality results and it is outstandingly economical. Use of woven wire mesh is in numerous applications such as fencing, agriculture, garden, greenhouse, architecture, building, construction, security, window guards, infill panels and so much more.
These screens are highly durable and strong. They correspond to each other to tightly lock into the place. Woven wire mesh screens are usually made in plain weave patterns. These screens add stability to the equipment and are commonly used as storage racks, baskets and more.
Hastelloy Wire mesh filter elements support cylinder with square perforations. They are used for moderate to large flow rates in inline filters, return line filters and suction line filters. Filter elements with a metal wire mesh are usually used as an affordable and reusable solution. Based on the requirements, different types of mesh are used like twill and dutch weave. Wire mesh screen elements are commonly used as surface filters which means that they become contaminated more rapidly than single use screens. For the reproduction, it should be kept in mind that screens with finer holes below 40 micro-m can be cleaned in the ultrasonic bath.
Cleaning
Stainless steel wire mesh elements should be cleaned after each use. Although only a specific level of cleaning is obtainable. In order to find the best result, the mesh should be cleaned by special method. The cleaning effect cannot although be predicted. It is mainly based on different conditions such as filtration rating, service pressure, type of particle.
Filtration rating: Fine filter material, complicates the cleaning process.
Service pressure: Higher service pressure, causes more firm hold of contaminated particles which are then embedded in the filter material.
Particle types: If the contamination comprises several fibers, the cleaning becomes complicated. Besides, it should be noted that with each cleaning procedure, it is merely feasible to restore about 80 to 90% of the initial filter area each time.
Stainless steel filter elements are comprising several layers of ss 316 mesh which are then sintered together to produce an integrated porous element. The central layer is of very fine gauge and states the filtration rates, this layer is then overlaid with internal and external layers of coarser mesh to offer support and protection.
