大型煤气管道盲板抽堵作业准备及作业流程

Preparation and Operation Process of Blind Plate Plugging for Large Gas Pipeline

DN1400以上大型盲板抽堵作业在钢铁企业煤气系统日常检修、工程扩建中出现频率较低,此类作业流程相对复杂,对人员、机具准备及配合要求高,带煤气作业时间相对较长,危险性较大。通过对准备流程、作业流程进行梳理,将抽堵作业全流程规范化、制度化,提高作业效率,确保盲板抽堵作业过程的顺利及安全。

The frequency of large blind plate pumping and blocking operation above DN 1400 is low in the daily maintenance and engineering expansion of gas system in iron and steel enterprises.This kind of operation process is relatively complex,which requires high preparation and cooperation of personnel and machines,and the operation time with gas is relatively long,with high risk.By combing the preparation process and operation process,the whole process of blind plate plugging operation is standardized and institutionalized to improve the operation efficiency and ensure the smooth and safe operation process of blind plate plugging.
