带压堵漏技术的研究现状及应用

介绍了带压堵漏技术工作原理与特点,概述了该技术的研究现状与发展,带压堵漏由夹具、密封剂、专用注剂工具和操作方法 4部分内容组成。其中,密封剂和夹具是这项技术的关键技术环节,密封剂性能应满足耐介质性、耐热性、适宜的固化时间、密封空间内残余收缩量要小,最好能不收缩等要求。结合带压堵漏技术在某炼油厂的实际应用,证明了价值所在,指出了带压堵漏包括对有关人员专门的培训、制定详尽的安全施工措施、配戴安全防护用品和在高空作业架设带防护栏的防滑平台等安全注意事项。带压堵漏技术还不够完善,有待进一步研究和提高,提出了一些可操作性的建议。

Online Leak Sealing Technology and Application

The working principles,characteristics of online leak sealing technology are introduced,and the status-quo and development of the technology are reviewed.The clamps,sealant and agent injector and their operating instructions are described.Sealant is the critical part of the technology,which shall have good adaptability to different media,good heat resistance performance,proper solidifying time and minimized residue concentration in sealing space.The commercial application of online leaking sealing technology in a refinery proves that it is a good technology for refinery operation.For application of this technology,the operating people should be trained,detailed safe construction measures be specified,safety protection tool be provided,and protection rail and platform be available for high-air operation.As online leak sealing technology is not perfect,further development and improvement are required.The online leak sealing should be performed effectively in a timely manner,and some operable recommendations are proposed.
