Stainless steel pipe filter


Stainless steel pipe filters are generally used for on-line filtration of small pipes. They are often used before the probe of the detection instrument. At the same time, they also have a fire resistance function. The filter medium is generally natural gas, hydrogen, acetylene and other flammable and explosive high-pressure gases. Stainless steel pipe filters The whole body is made of forged steel, which is corrosion resistant and has a long service life. The internal filter element is generally stainless steel sintered mesh or powder sintered, which can be repeatedly washed and reused, and it is easy to maintain and does not need to replace the filter element.
