The stainless steel pleated metal sintered filter cartridge uses the standard five-layer sintered mesh (protective layer, precision control layer, dispersion layer, multi-strengthening layers) as the main filter medium. Made by stacking five layers of stainless steel wire mesh and vacuum sintering, it features high strength, corrosion resistance, good permeability, stable precision, and backwash capability. It can operate under high temperatures (≤600 °C) and oxidizing atmospheres with excellent thermal shock resistance. It adopts a multi-dimensional honeycomb capillary structure, providing superior separation and noise reduction. Corrosion and rust resistance are comparable to dense stainless steel. It can be fabricated into various complex structures with materials including 304, 316, 316L, 304L, Hastelloy (C276/C22), 904L, 2205, 2507, etc. Suitable for liquid filtration in petrochemical, nuclear power, and chemical industries.
