Analysis and Improvement of Corrosion Cause of Seawater Butterfly Valve Disc in Nuclear Power Station

Abstract

Abstract

Various factors which may cause corrosion are investigated to solve the corrosion issue of seawater butterfly valves disc used in nuclear power station.The system working condition, butterfly valve disc material selection, casting process, environment condition and other factors were analyzed to find the possible causes of the corrosion of the disc. Finally, aiming at these factors, some targeted measures are put forward to provide solution for corrosion of seawater valves.
