Factory Introduction






Stainless steel filter elements are divided into stainless steel sintered mesh filter elements, stainless steel wire mesh folded filter elements, stainless steel sintered felt filter elements, metal powder filter elements, etc. Stainless steel filter elements generally have high working pressure and high working temperature. If the filter element end cap is glued, it generally cannot work at high temperature. The filter element glue will break and the end cap will fall off easily. Therefore, stainless steel filter elements are generally welded to connect the end cap and the filter material joint.
Characteristics of welded stainless steel filter element:
1. Stainless steel filter element has good filtering effect, uniform and stable pores, good air permeability, small pressure loss, high filtering accuracy, stable separation effect and filtering performance;
2. Stable shape, better impact resistance and alternating load resistance than other metal filter materials;
3. Easy to backflush, washable, strong regeneration ability, can be repeatedly cleaned, long service life, high material utilization rate.
4. Can effectively remove suspended matter, etc., with excellent filtering accuracy.
5. Excellent mechanical strength, no need for external skeleton support protection, simple installation and use, easy maintenance, good assembly.
6. Resistant to rapid cooling and heating, oxidation resistance, acid and alkali corrosion, suitable for higher working temperature and heat shock resistance, also suitable for use in high temperature, high pressure and highly corrosive environments;
