An Innovative Approach to Anticorrosive Protection of Stainless-steel Pipeline Structures at Nuclear Power Plants

Abstract

The article discusses the issues of dangerous corrosion destruction of stainless steels, which are the main structural material of nuclear power plants. The applied methods of protection against local corrosion and corrosion cracking are described. The authors have proposed a method of corrosion protection by applying alternating current to sections of a pipeline separated by an electrically insulating insert. A theory describing the effect of weak alternating current on the kinetics of the corrosion process of a steel pipeline is briefly presented. The presented innovative approach to the issue of corrosion protection of technological metal pipelines will be of interest to specialists of enterprises and organizations related to the issues of corrosion cracking of stainless steels and nickel alloys to identify ways to protect structures of nuclear power plants from it.
