摘　　要：“带压焊接堵漏技术”是指金属设备、管道、容器、阀门等一旦出现裂纹或孔洞等,发生介质向外泄漏,为避免非计划停车造成损失,需要在适当降低或完全不降低工艺介质温度、压力的条件下,通过尖平铲锤击挤压焊接法等带压焊接方法使之重新达到密封不泄露的一种特殊技术手段。经过多次现场操作,证明该方法是行之有效的应急处置办法。用最短的时间实施焊接堵漏,避免了非计划停车造成的经济损失。"Leak plugging technology with pressure welding"refers to a special technical means that once cracks or holes occur in metal equipment,pipelines,containers,valves,etc.,media leaks out,in order to avoid losses caused by unplanned parking,it is necessary to reduce the temperature and pressure of the process medium appropriately,or use pressure welding methods such as squeezing welding with a sharp shovel to make it re-seal without leakage.After many on-site operations,this method has proved to be an effective emergency treatment method.Welding leaks are implemented in the shortest time to avoid economic losses caused by unplanned parking.
