总结带压堵漏技术在氯乙烯装置上近两年来的实际使用情况 ,对不同的腐蚀介质、不同工况下的不同堵漏方法进行了统计、比较。通过实践证明这些堵漏方法是行之有效的 ,在带温、带压下消除了泄漏 ,保证了生产连续进行 ,对相似装置的带压堵漏有一定的参考作用 Summarize the actual usage of the pressure-plugging technology in the past two years on the vinyl chloride plant, and make statistics and comparison on different corrosive media and different plugging methods under different working conditions. The practice proved that these plugging methods are effective, with the temperature, with pressure to eliminate the leak, to ensure the continuous production, similar devices with pressure plugging there is a certain reference
