Sintered felt filter element

Sintered felt filter element is the applications of the sintered felt; it is made ​​of sintered felt after cutting, precision welded sintered filter. The most important point of Sintered felt filter element is that a large number of high-precision welding is used. To ensure roundness and flat, Sintered felt filter element is sintered after using rolling seam welding process and the method of correction weld, it can make the overall look more beautiful. Stainless steel sintered felt, also known as non-woven fabric, is sintered by extremely fine metal fibers (diameter accurate to micron), and then after non-woven spreading, stacking and high temperature sintering, Stainless steel sintered felt is formed by a different aperture hole gradient which can be controlled to obtain a high filtering accuracy and greater dirt holding capacity. A three-dimensional mesh, porous structure, porosity, pore size distribution and other characteristics, it can continuously maintain the filtration fabric filtering effect. Due to the above structures and characteristics which makes stainless steel sintered felt have effectively compensated for blocking and wearing weaknesses, it also makes up for the fragile powder filtration products and the lack of flow, so the ordinary filter paper, cloth is not comparable to the temperature and pressure of characteristics, and thus stainless steel sintered felt is the ideal filter material for high-temperature resistance, corrosion resistance, high-precision environment.

Features:

(1) Large dust holding capacity, high filtration precision, pressure raises slowly, cycle length
(2) High porosity and excellent permeability, small pressure loss, high flow.
(3) Corrosion resistance, high temperature resistant, resistance to corrosion of acid, alkali, organic solvents and drug,at 480 ℃ environment for long-term use.
(4) Easy processing, forming, and welding.
(5) Be produced according to user requirements of particularly enhanced, thickened type, intensive network type and various other specifications.
(6) Standard material: SUS316L or iron-chromium-aluminum fibers.

Applications

    Stainless steel sintered filter with excellent filtration precision and is an ideal filter material for high temperature resistance, corrosion resistance, and high-precision environment. It is Widely used in the polymer filtration, oil, petrochemical, electronic hot temperature gas dust removal, oil refining process of filtration, viscose filtration, ultra-filtration filter, pump protection filter, membrane support, catalyst carrier, automotive airbag , ships, aircraft fuel filter, hydraulic system filter.

Note: The difference between sintered filter and ordinary filter
          Processing technology of sintered filter is different from ordinary filters; The most important point of Sintered felt filter element is that a large number of high-precision welding is used. To ensure roundness and flat, stainless steel sintered filter is sintered after using rolling seam welding process and the method of correction weld, it can make the overall look more beautiful. In this way, it is helpful of the next step to prepare welded filter. The sintered mesh of sintered filter is welded on the end caps at both ends by stainless steel, the welding process can not burn sintered wire mesh, to prevent local burn and resulting not achieve filtration filter, so the welding of the welding process must use argon. All the above must wear special overalls and special welding equipment, welding technology requirements for workers are more stringent, it can prevent the sintered filter from bubbling after welding experiment bubbling air leak in the pressure range. Once that happens, all will be scrapped.

Note:  

Filtration and dirt holding capacity is measured according to the provisions of GB/T18853-2002.

Measure of the bubble point pressure is specified for GB/T5249.

Air permeability is measured according to the provisions of GB/T53453, pressure difference is 200Pa, and medium is air.

Fracture strength is measured by the regulations GB/T228.
