不停车置换带压打孔在化工生产中的应用

Application of Non-parking Replacing Drilling with Pressure in Chemical Production

化工生产是个连续性非常强的过程,但是在化工厂投产的整个寿命期内改造是不可避免的,在这个改造的过程中管道增设和联接经常需在旧管道上进行开孔作业。化工管道中通常是高危险性气体或者是高危险性的液体,为了保证安全开孔作业通常需要停产进行置换作业。从经济性上来说,停车置换打孔的代价过大,为了保证连续性生产节省生产成本,这时便需要进行带压开孔作业。

Chemical production is a process with strong continuity, but it is inevitable to transformation in the whole life period of the operation of chemical plant. In the process of transformation, piping installation and connection often need to operate on old pipelines. In chemical pipelines, there are usually high risk gases or liquids. In order to ensure safe drilling operations, replacement operations are usually required. In terms of economy, the cost of parking replacement drilling is too high. In order to ensure continuous production and save production costs, it is necessary to carry out pressure drilling.
