Corrosion Analysis of Fire Water Pipeline in a Nuclear Power Plant
The fire sprinkler pipes of the conventional island sprinkler system of a nuclear power plant frequently suffer from corrosion and perforation.This article systematically analyzes the operating environment,regular testing procedures,anti-corrosion measures,and corrosion morphology characteristics of fire sprinkler pipelines.On the surface of the results,the fire sprinkler pipeline designed with internal and external galvanized anti-corrosion measures is a pre action fire extinguishing system with internal air circulation.After conducting regular tests,some horizontally arranged pipelines have residual water,which causes corrosion perforation under oxygen-containing conditions.
