Salt water solution is a common solution in chemical production, which has a corrosive effect on membranes and some metal containers. Often appear in the corrosion phenomenon is a point, the impact of corrosion on the stainless steel reactor is relatively large, if the corrosion is serious, it will have a great impact on the function of stainless steel products. Stainless steel is generally corroded in salt solution, causing damage to the passivation film on the surface. Other reasons for pitting corrosion are the influence of some chemical substances and seawater organic substances attached to stainless steel products. In the process of attachment, a natural oxygen concentration battery is formed, which is corroded after formation.

Stainless steel is generally corroded in salt solution, causing damage to the passivation film on the surface. Other reasons for pitting corrosion are the influence of some chemical substances and seawater organic substances attached to stainless steel products. Natural oxygen concentration battery is formed in the process of attachment. After formation, corrosion will occur in large numbers and become more serious. In the case of high-speed flow of salt water, or stainless steel products of different structural designs, the corrosion is relatively small. The atmospheric corrosion resistance of stainless steel is basically changed with the chloride content in the atmosphere. Therefore, proximity to marine or other sources of chloride pollution is extremely important for corrosion of stainless steel. A certain amount of rainwater is important only when it acts on the chloride concentration of the steel surface.
When using a stainless steel reactor, in order to keep the stainless steel material from being excessively corroded by the salt solution, a certain water flow rate can be maintained to prevent the accumulation of impurities on the surface and reduce the conditions for the chemical reaction. In addition, it is best to reduce the appearance of gaps in the design of stainless steel reactors, and reduce the use of thick-walled components, and reduce the conditions for the reaction from the stainless steel reactor itself.
