Why use stainless steel pickling passivation methods __ metal wire mesh products co. , LTD

Common acid-base with stainless steel wire mesh is mainly used in acid, alkali environment conditions screening and filter, gas, liquid filtration and separation with other media. Stainless steel wire mesh stainless steel mesh, nickel wire, copper wire as the raw material of stainless steel has good corrosion resistance, high temperature oxidation resistance, good low temperature performance and excellent mechanical and add to r. So it is widely used in chemical, petroleum, power, nuclear, aerospace, Marine, pharmaceutical, light industry, textile and other departments. In a stainless steel equipment and parts in the molding, assembly, welding, weld inspection ( Such as inspection, pressure test) In the process of its construction and tag with surface oil, rust, non-metallic dirt, low melting point metal pollutants, paint, welding slag and splash, etc. The main purpose is to against corrosion. The corrosion resistance of stainless steel relies mainly on the surface passivation membrane, if the film is incomplete or flawed, stainless steel filter will corrode. Engineering are usually for pickling passivation treatment, make the corrosion potential of stainless steel to the greater. Stainless steel surface cleaning, acid pickling and passivation, in addition to the limit to improve the corrosion resistance, and to prevent product contamination and aesthetic effect. Used in direct contact with the corrosive medium phase, starting from guarantee corrosion resistant corrosion resistance, acid pickling passivation should be put forward. But for the weld of the stainless steel equipment for pickling passivation is needed. Use of nuclear engineering, some chemical plant and other requirements strictly, in addition to the pickling passivation, and using high purity medium to fine clean or mechanical, chemical and electrolytic polishing finishing processing. Some substances affect the surface quality of stainless steel wire mesh equipment and parts, destroyed the surface oxide film and reduce the steel of the general corrosion resistance and resistance to local corrosion performance ( Including pitting, crevice corrosion) And even lead to stress corrosion cracking.
