原油管道防腐保温补口技术选择及质量控制

Technical selection and quality control of anticorrosion and thermal insulation for weld joint of oil pipeline

以天津港-华北石化原油管道工程为例,介绍了埋地输油管道防腐保温补口的主要方法,阐述了防腐保温补口技术的关键问题及质量控制。通过对该管道沿线地质情况对现场施工的特殊技术要求,确定了适用于本工程管道防腐保温补口技术的最优方案。

By taking Tianjin Port-North China petrochemical oil pipeline as an example, the commonly used anticorrosive and thermal insulation repairing methods for the buried ground transportation oil pipeline are introduced. The critical problems and quality control of the anticorrosion and thermal insulation repairing technologies are focused. According to the special technical requirements of geological conditions on the construction site, the optimal solution suitable for anticorrosive and thermal insulation repairing of oil pipeline in this project is determined.
