摘要：  为了研究海管立管腐蚀缺陷修复技术及其施工工艺质量控制问题，以渤海某平台海管为对象，从腐蚀环境、防护层等方面分析了海管立管腐蚀缺陷的原因。从腐蚀立管基底表面处理、防腐膏填平、缠绕黏弹体防腐胶带、缠绕PVC防护带、缠绕水固化环氧玻璃钢外护带等环节介绍了海管立管修复关键技术及其施工工艺主要内容。同时对施工质量控制环节做了详细的论述。总结出海管立管修复需从技术方案、表面处理、施工工艺、技术检测及现场恢复等方面进行整体性质量控制。

Abstract:  In order to study the corrosion defect repair technology and its construction process quality control, based on the analysis of the corrosion environment and protective layer, the corrosion defects of the riser in Bohai are analyzed. From the aspects of riser base surface treatment, corrosion and anticorrosive ointment filling, viscoelastic tape winding, the winding of PVC protective belt, and the winding of water curing epoxy glass steel belt, we introduce the sea pipe repair key technology and construction technology of riser. At the same time, after detailedly introducing the riser repair construction quality control, the riser repair reinforcement scheme, surface treatment, construction technology, detection technology, site restoration and other aspects are described for the overall quality control.
