How to deal with the chloride ion corrosion of stainless steel pneumatic valve

we know that the industry of chlorine ion in water, is a kind of can make the corrosion of metal ions, it mainly for general corrosion of carbon steel and stainless steel pitting corrosion and stress corrosion, etc. Stainless steel pneumatic valves are used in all kinds of industrial cooling water, has a comprehensive corrosion rate is very low, but in the actual industrial production conditions, the stainless steel equipment, especially all kinds of industrial water cooler, corrosion damage accident is very serious and the corrosion damage by the local corrosion ( Mainly pitting corrosion and stress corrosion cracking) .
with the growing shortage of water resources, the rational water and raise the repeated utilization ratio of water looms, the highest allowances of chloride ions in the circulating cooling water is closely related to the concentration ratio and operating conditions, our country some large petrochemical enterprise the important reason for the low concentration ratio of circulating water is restricted by the chloride ion concentration.
so we must intensify the chlorine ion in aqueous solution, the corrosion behavior of metals, the development of resistance to chlorine ion corrosion inhibitor, improve the concentration ratio of circulating water, energy saving, water saving.
