在火力发电厂,中低压管道焊口的渗漏时常发生,特别是重要管道的渗漏直接影响机组的正常运行,危及设备和人身的安全,造成的经济损失也甚为可观。遇到这种事故时,应迅速查明管内的压力、介质及渗漏处的情况,采取应急处理(这种处理往往在不停机、炉的情况下进行)。现将在管道工作状态下补焊及采取的措施分别介绍如下。 In thermal power plants, the leakage of low and medium pressure pipe welds often occurs. In particular, the leakage of important pipelines directly affects the normal operation of the unit, endangering the safety of equipment and people, resulting in considerable economic losses. In the event of such an accident, prompt attention should be given to the pressure in the pipe, the media and the situation of leakage, and emergency handling should be carried out (this treatment is usually carried out without shutting down the furnace). Will now work in the pipeline repair welding and the measures taken are described below.
