复合内衬技术在旧管线修复和新管线建设中的应用

The application of the composite lining in pipeline rehabilitation and pipeline construction

复合内衬层具备防腐和保温的双重功能，已在中原油田6km旧管线修复施工中成功应用，具有明显的经济和社会效益，并为复合内村工艺在新管线建设中的应用奠定了技术基础。本文介绍复合内村层的特性、施工工艺特点和在管线修复与建设中的效益。

The composite lining is possessed of the dual functions of thermal insulation and anti - corrosion.This technique has been successfully used ln a 6km pipeline rehabilitation project in Zhongyuan Oil Field, and great economic and social efficiencies are gained. It has laid a foundation for the application of this technique in constructing new pipelines. This paper introduces the properties of the composite lining, the technological characteristics of construction, the efficiencies of the techinque in pipeline rehibilitation and construction
