摘　　要：由于油气管道输送的介质易燃、易爆,管道一旦发生腐蚀穿孔,可能会导致灾难性事故,其安全问题日益受到重视。如何通过新材料、新技术、新工艺和新设备,来抑制和减缓金属管道的腐蚀,特别是特殊环境下的管道腐蚀,已成为管道防腐行业的重要课题。本文通过一些具体的工程案例介绍了新型防腐材料粘弹体和压敏胶型热收缩带在特殊环境中的长期应用效果,表明了粘弹体和压敏胶型热收缩带在盐碱地、海边滩涂和隧道等特殊环境对金属管道具有良好的长效密封防腐效果,尤其适用于在役管道防腐修复。Owing to the flammable and explosive characteristics of the medium conveyed by oil and gas pipelines,once the pipeline undergoes corrosion perforation,it may result in catastrophic accidents.Thus,the safety issue has gained increasing attention.How to inhibit and retard the corrosion of metal pipelines,especially in special environments,through new materials,new technologies,new processes,and new equipment has become a significant topic in the pipeline anti-corrosion industry.This paper presents the long-term application effects of the new anti-corrosion materials,namely viscoelastic and pressure-sensitive heat shrinkable tape,in special environments through certain specific engineering cases,demonstrating that the viscoelastic and pressure-sensitive heat shrinkable tape have excellent long-term sealing and anti-corrosion effects on metal pipelines in special environments such as saline-alkali land,seaside tidal flats,and tunnels,and especially suitable for the anticorrosion repair of in-service pipelines.
