摘　　要：本文主要通过分析“发汗”管道与非“发汗”管道在修复时的工况差异,根据“发汗”管道的修复难点,开展了湿用粘弹体+压敏胶型热缩带应用于“发汗”管道防腐层修复室内及现场应用试验,验证了该防腐层结构用于“发汗”管道防腐层修复的可行性和可靠性。This paper mainly analyzes the differences in working conditions between‘sweating’pipelines and non-’sweating’pipelines during the repair process.Based on the challenges in repairing‘sweating’pipelines,the paper carries out indoor and field application tests of wet viscoelastic tape combined with heat shrink pressure-sensitive tape for the anti-corrosion layer repair of‘sweating’pipelines.It verifies the feasibility and reliability of this anti-corrosion layer structure for the repair of the anti-corrosion layer of‘sweating’pipelines.
