摘要
受到介质对设备的腐蚀、流体的冲蚀、温度压力、密封损坏以及焊接遗留的缺陷等因素的影响,石油炼油和化工蒸馏装置的管道、阀门等连接部位及其容器壁上都不可避免会出现跑、冒、漏等问题,而这些问题亟需及时解决,否则将会影响石油炼化蒸馏装置运行的安全性和稳定性。为此,不少石油炼化蒸馏装置系统开始使用方便、安全且经济性较好的带压堵漏技术,它能生产装置不停工的状态下实现对容器承压部件进行堵漏的作用,受到了用户的广泛欢迎。为此,介绍了带压堵漏的技术原理及应用原则,夹具制作等的关键工艺,以及该技术在石油炼化蒸馏装置中的应用。
Under the influence of equipment corrosion, fluid erosion, temperature, pressure, seal damage and weld inherited defects and other factors, different leakage problems are inevitable in oil refining and chemical engineering devices, and these problems need to be timely resolved, otherwise they will affect operation safety and stability of these units. Therefore, convenient, safe and economic pressure seal technology has been widely used in many oil refining and petrochemical distillation devices; it can realize the plugging of pressure vessel components without shutdowri, so it is widely welcomed by the users. In this paper, the principle of pressure sealing technology was introduced as well as its application in oil refining and petrochemical distillation devices.
