Technology Improvement for Pipeline Anticorrosion of Sea Water Cooling System in Qinshan Nuclear Power Plant

On the background of reconstruction of sea water cooling system pipeline,this paper analyzes the status of the anticorrosion of the sea water cooling water system pipe.Taking the generator air cooler water pipe with most serious corrosion as an example,the cause for the serious corrosion is analyzed,and a new technology for anticorrosion is developed,the improvement measures is proposed,through continuous improvement,and a good anticorrosion result is obtained.
