Anti-corrosion method and structure of pipeline connecting fastener

The invention provides an anti-corrosion method and structure for a pipeline connecting fastener. The method comprises the steps that in the process of installing the pipeline connecting fasteners, viscoelastic body anti-corrosion paste is adopted for protecting the pipeline connecting fasteners such as anchor bolts, steel washers and nuts, a PVC sleeve is installed on a connecting steel plate with the anchor bolts as the center, and forming of the viscoelastic body anti-corrosion paste is facilitated. According to the method, the cold flow characteristic and the good anti-corrosion effect of the viscoelastic body anti-corrosion paste are utilized, long-term effective corrosion protection is formed for the pipeline connecting fastener, corrosion damage of adverse factors such as high humidity and high temperature to the pipeline connecting fastener is effectively reduced, the operation and maintenance cost can be reduced, and the safety and reliability of pipeline operation are improved. 本申请提供了一种管道连接紧固件的防腐方法和
