摘要: 在南海西部某气田群开发工程项目双相不锈钢管段到货验收时,发现少量管段内壁存在细微裂纹等缺陷。基于这一实际情况,研究出内窥镜检测系统,实现了双相不锈钢管段管道内壁状态的现场可视化检验。该检测技术使用标准光学探头扫描管道内壁,通过标准运输/存储机箱设备,将检验结果以视频和图片的形式存档于存储设备,建立双相不锈钢管段内壁情况的可视化电子档案。现场应用结果表明,内窥镜检测技术能够及时有效排除管道内壁诸如裂纹、折叠、划痕等缺陷,该技术在工程实用中取得了良好的效果,可为今后类似工程项目提供借鉴。

Abstract: Combined with the actual situation of the presence of fine cracks on the inner wall of a small number of pipe sections during the acceptance of the duplex stainless steel pipe section of a gas field group development project in the western South China Sea, the endoscopic detection technology was developed and the on-site visual inspection of the inner wall of the duplex stainless steel pipe section was realized. The inspection technology uses a standard optical probe to scan the inner wall of the pipe and archive the inspection results in a video and picture format on a storage device through a standard transport/storage chassis device to create a visual electronic file of the inner wall of the duplex stainless steel pipe section. The field application results show that the endoscope detection technology can effectively and effectively eliminate the defects caused by the inner wall of the pipeline such as cracks, folds and scratches in the production process. The detection technology has achieved good results in engineering and practical, and can be used for similar projects in the future. It can provide experience for reference.
