随着油气田建设的不断发展,管线不停产连头技术的应用越来越广。在工作管线上铰孔,进行管线不停产连头,既能保证工作管线照常生产,又能在工作管上接出支管,对加快油气田建设十分有利。但是,在施工中如果对关键部位不予以重视,不采取有效措施,则轻者会造成不停产连头施工的失败,重者会给工程留下重大隐患。现将施工中应注意的问题和应采取的措施加以简单的介绍,供读者参考。1.焊缝与垫片
With the continuous development of oil and gas field construction, the continuous production of pipelines has become increasingly widespread. The reaming of the working pipelines and the continuous production of pipelines at the production line not only ensure the normal production of the working pipelines, but also take over the branch pipes on the working pipelines, which is very favorable for accelerating the construction of oil and gas fields. However, if you do not attach importance to key parts during construction and do not take effective measures, lighter people will cause unsuccessful production of joint construction failures, and serious ones will leave major hidden dangers to the project. Attention should be paid to the problems that should be noted during construction and the measures that should be taken for the reader’s reference. 1. Welds and gaskets
