管道塑膜管内衬施工方法

Installation method of pipeline plastic film inner lining

油田污水矿化度高、腐蚀性强,对管道的腐蚀相当严重。为防止管道的内腐蚀,采用了管道塑膜内衬技术,经过几个工程的实践,收到了良好的效果。介绍了管道塑膜内衬的施工工艺和内衬特点,经比较其施工工期短、造价低。管道塑膜内衬技术是对油田管道在线修复的新施工方法。

Waste water from oil field presents high salinity and strong corrosiveness, and will be a serious corrosive medium to pipeline. In order to prevent pipeline from corrosion, pipeline plastic film inner lining is applied and fine result is obtained through several engineering practices. The article introduces construction process of the plastic film inner lining and its characteristics of short construction term and low cost by comparison. Pipeline plastic film inner lining technology is a new construction method for oil field pipeline rehabilitation.
