| description | The invention relates to a plugging method for a crude benzene pipeline. The plugging method comprises the steps of cutting a leakage section, manufacturing a connecting section pipeline and an inner plugging plate, plugging the crude benzene pipeline at a fracture through the inner plugging plate, introducing nitrogen into the crude benzene pipeline, welding a flange on the crude benzene pipeline, installing the connecting section pipeline through the flange and the like. The method can ensure safe and reliable fire operation on the crude benzene pipeline, reduces the safety risk, and shortens the operation time of the crude benzene pipeline.
本发明涉及一种粗苯管道堵漏方法，包括切割泄漏段、制作连接段管道及内堵板、通过内堵板封堵断口处的粗苯管道、向粗苯管道内通入氮气、在粗苯管道上焊接法兰、通过法兰安装连接段管道等步骤；本发明能够确保安全可靠的对粗苯管道进行动火作业，降低安全风险，缩短粗苯管道作业时间。 |
