输油气管道在运行过程中会受到自然环境和人为因素的破坏,造成管体缺陷或泄漏事故。对管道采取不停输修复是延长其使用寿命、降低管道公司经营成本的有效方法。从国外旧管道不停输整修技术的现状入手,重点介绍了目前国外采用的先进设备和技术,其中包括管道旧覆盖层清除系统、管道表面处理系统、管体加强套等,并针对我国实际情况,建议尽快开展开发引进工作。
Oil and gas pipelines in the operation of the process will be subject to natural environment and human factors, resulting in body defects or leaks. The non-stop pipeline repair is to extend its service life and reduce pipeline companies an effective method of operating costs. Starting with the status quo of repairing and repairing old pipelines in foreign countries, this paper mainly introduces the advanced equipment and technologies currently used in foreign countries, including the old overburden removal system of pipelines, the pipe surface treatment system and the pipe strengthening kit. In view of the actual situation in our country , It is recommended to carry out development and import work as soon as possible.
