Durable
Metal powder sintered porous material is made of metal or alloy
powder by forming and sintering at high temperature and with a
rigid structure.
Stainless steel sintered porous material is stainless steel 304,
304L, 316, 316L powder as the raw material, after screening,
molding, sintering microporous material.
- Features of stainless steel sintered porous materials
Stainless steel sintered porous material has excellent corrosion
resistance, oxidation resistance, wear-resistance, and mechanical
properties.

- Medium purification and flow limitation for pneumatic components,
lubricants, fuels, and hydraulic pressure systems.
- Chemical dye industry of high - temperature decarburization.
- Precision filtration of liquid raw materials, products and
pharmaceutical intermediates in the chemical industry.
- The chemical raw material production process in addition to
impurity filtration, material decarburization filtration, and fine
filtration.
- Stainless steel sintered porous material allows for the use of the
environment
Nitric acid, sulfuric acid, acetic acid, oxalic acid, phosphoric
acid, 5% hydrochloric acid, molten sodium, liquid hydrogen, liquid
nitrogen, hydrogen sulfide, acetylene, hydrogen, carbon dioxide
gas, water vapor, etc.
- Precautions for the use of stainless steel sintered porous
materials
- During installation, disassembly and clean avoid scratches,
collisions and falls on hard objects.
- When using, the filtrate is filtered from the outside in to avoid
the reverse direction.
- Avoid instant pressurization when the filter element works.
- When the filtration efficiency is less than 50%, the filter element
should be cleaned in time.
- If the filter element is not good after online back blowing and
backwashing, it should be removed and cleaned in time.
- When cleaning the filter element, the first backflow with pure gas,
backflow pressure is 1.5 times the working pressure, each time for
3-5 seconds, and 4-6 times, then backwash with clean liquid for 3-5
minutes, repeat 2-3 times.
