Stainless steel porous sintered filter element and sintered microporous stainless steel filter element (including tube type and plate type) are micro-filter elements made of 316L powder as raw material, through sieving, molding, and sintering. High filtration precision, good air permeability, high mechanical strength, high material utilization rate, suitable for higher working temperature and heat shock resistance. Widely used in pneumatic components, chemical industry, environmental protection and other fields. Porous elements of various shapes, structures, different particle sizes and porosities can be produced according to user requirements, such as: covers, caps, sheets, tubes, rod-shaped filter elements. Therefore, the stainless steel powder sintered filter material has unique excellent performance due to its high-tech material composition and special molding process:

1. High temperature resistance, normal use below 500 degrees Celsius.

2. High filtration accuracy, stable pores, can effectively remove suspended solids and particles, etc., with excellent filtration accuracy and good purification effect.

3. Good air permeability and low pressure loss. The porosity is high, the pore diameter is uniform, the initial resistance is small, it is easy to blow back, it can be regenerated online, it is easy to clean, it has strong regeneration ability and long service life.

4. High mechanical strength, good rigidity, good plasticity, no need for external frame support protection, simple installation and use, convenient maintenance, good assembly, and can be welded, bonded and machined.

5. Uniform pores, especially suitable for occasions with high uniformity requirements such as fluid distribution and homogenization.

6. Filtration accuracy: 1~50μm.

7. No particles fall off, and no secondary pollution of the original solution.

8. Good mechanical performance, low pressure difference, large flow rate, press filter and suction filter, simple operation.

9. Good corrosion resistance, and can be used stably in environments such as nitric acid, sulfuric acid, acetic acid, oxalic acid, phosphoric acid, 5% hydrochloric acid, molten sodium, liquid hydrogen, liquid nitrogen, hydrogen sulfide, acetylene, water vapor, hydrogen, and carbon dioxide.

10. The molding process is good, and the overall length without welding can reach 1200 mm. Stainless steel powder products are formed at one time without cutting, the effective utilization rate of raw materials is high, and materials are saved to the greatest extent. It is especially suitable for components with large batches and complex structures.
