Melt filter element is also known as metal filter element and stainless steel filter element.
The main filter materials of the filter element are mainly stainless steel woven mesh and stainless steel fiber sintered felt.
The stainless steel woven mesh is woven from stainless steel wire, and its pleated filter element has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no falling off of the wire mesh, and long filtration cycle.
What joints are there for the stainless steel melt filter element produced by our company?
The company can also customize according to customer needs---free design of filtration solutions.
Application areas:
1. Petrochemical: oil refining, chemical production and separation and recovery of intermediate products
2. Metallurgy: used for filtration of hydraulic systems of rolling mills and continuous casting machines
3. Textile: purification and uniform filtration of polyester melt during wire drawing
4. Electronics and pharmaceuticals: pre-treatment filtration of reverse osmosis water and deionized water
5. Thermal power and nuclear power: purification of oil in the lubrication system, speed control system, bypass control system of gas turbines and boilers, purification of feed pumps, fans and dust removal systems
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;
