日前,中油管道防腐工程公司展示了热收缩带补口施工装备及配套技术。该技术根据长输油气管道补口安装工艺的不同,分为湿膜和干膜2种热收缩套安装工艺,填补了国内相关领域的空白。中国石油油气管道总里程已突破5×104km,管道建设达国际水平。但近年对在役管道的检测发现,由
Recently, PetroChina Pipeline Corrosion Engineering Company demonstrated the construction equipment and supporting technology of heat shrinkable band filler. The technology is divided into two kinds of heat shrinkable sleeve installation process of wet film and dry film according to the different installation process of long pipeline of oil and gas pipelines to fill the gap in related fields in China. The total mileage of PetroChina’s oil and gas pipelines has exceeded 5 × 104km and the pipeline construction has reached the international level. In recent years, however, testing of in-service pipelines has been found
