First-time hot work operation process in high risk area during the refinery plant maintenance
During the overhaul of one refinery,7 cut-off valves needed to be added in the loading and unloading unit of the oil product workshop.The hot work location was special,with difficulty in pipeline sampling at the hot work site,and it was the first-time hot work to be conducted,with a tight schedule.In view of the above situation,the first-time hot work construction process and drilling sampling plan were developed.The preparation work before construction,specific safety protection measures,drilling sampling analysis process,and operation procedures were introduced in detail.The first-time hot work was carried out according to the developed process,completing the installation of 7 cut-off valves safely and efficiently.This solved the problem of conducting first-time hot work in high risk area during the maintenance,and the quality and safety were effectively controlled during the operation process.
