1 概况某化工厂的不锈钢萃取塔于1999年5月开始运行,于2000年6月发现萃取塔有不同程度的泄漏现象。为了维持生产,该化工厂多次焊接修复泄漏处,均不见效,且有越修越严重的态势。应该化工厂要求,我公司于2001年7月承担了萃取塔的修理任务,修理后即投入运行,至今运行状况良好。现将该萃取塔泄漏原因及焊接修复过程分别叙述如下:
1 Overview A chemical plant stainless steel extraction tower in May 1999 began to run in June 2000 found that the extraction tower have different degrees of leakage. In order to maintain production, the chemical plant several times to repair leaks, are not effective, and the more serious the more the repair situation. Should the chemical plant requirements, our company in July 2001 assumed the extraction tower repair tasks, put into operation immediately after repair, running in good condition so far. Now the extraction tower leakage and welding repair process are described as follows:
