In long-distance water transmission pipeline engineering,pipeline corrosion usually greatly affects the service life of the pipeline and pollutes the water quality inside the pipeline.In order to improve the service life of the pipeline,anti-corrosion coatings can be installed inside and outside the pipeline and combined with cathodic protection to protect the water transmission pipeline.This paper introduces,analyzes,and studies the anti-corrosion technology of water pipelines based on practical engineering cases,and provides commonly used pipeline anti-corrosion measures for metal pipelines of different materials.Practice has proven that pipeline anti-corrosion measures can indeed slow down the damage caused by corrosion on pipelines,and have high practicality and economic rationality.
