Pressure hot tap plugging, plugging holes with pressure gas pipeline

The process may stop output of pipe repair, rescue, plus access bypass line, replacement or additions valve instrument, the replacement pipe, the station area transformation. Especially those high pressure transmission pipelines flammable, poisonous liquid or gaseous medium. The process of the adaptation medium pressure and temperature inside the transfer line: a) a bypass hole open: Φ20-Φ1600 ≤6.4MPa -60 ℃ -350 ℃ b) start plugging holes: Φ20-Φ1000 ?? ≤6.4MPa ?? - 30 ℃ -250 ℃ c) special process:? alloy, stainless steel hole plugging process d) according to the user the actual situation to do a special block?. ? (Temperature and pressure) to open the bypass hole:? Pipeline hot tapping means in a closed state, in a kind of mechanical cutting mode processing operation technology circular hole in the pipeline operation. When in service the pipeline needs to install the manifold, we can use the pipeline hot tapping technology to complete, will not affect the normal transmission pipelines, but also ensure that the connection work safe, efficient and environmentally friendly complete line of new and old.
