pickling process

- Oct 26, 2020-

The pickling solution of pickling process is generally a mixture of various acids, mainly sulfuric acid, nitric acid and hydrofluoric acid. These mixed acids have strong corrosivity, strong oxidation and high temperature of corrosive medium, which puts forward high requirements for corrosion resistance of anticorrosive materials. Stainless steel pickling production line process from production to waste water and waste gas recovery system, each link has a strong corrosion state, so the selection of anti-corrosion materials is directly related to the normal use of equipment, workshop floor, trench, environmental protection recovery system of waste water and waste gas.
