某输气管道因扩建需进行动火作业，采用TG-NET软件对停输后管存天然气持续供气时间以及恢复供气时间进行分析，确定停输技术可行。提出三个动火方案：停输常规动火、停输单侧带压封堵动火、不停输双侧带压封堵动火，并对三种动火方案进行技术经济对比，得到方案一即停输常规动火方案为最优。现场实施情况表明采用方案一顺利完成了本次动火作业，取得了预期效果。
Due to the need of expansion, hot work will be conducted in Certain gas pipeline. Applied is software TG-NET to analyze the continuous supply time of gas stored still in the pipeline after shutdown and gas resupply time so as to determine the technical feasibility of shutdown. Proposed are three solutions for hot work: conventional hot work after shutdown, the unilateral plugging hot work with pressure after shutdown and bilateral plugging hot work with pressure without shutdown. Compared are technical and economic factors of the three solutions and the optimal solution has been confirmed: the conventional hot work after shutdown. Actual in-site operation results show that solution NO.1 was completed successfully and the expected results have been achieved.
