Tests of the Power of Siberia pipeline crossing across the Gilyuy River have been completed
STROYGAZMONTAZH has completed pneumatic tests of the crossing of the Power of Siberia gas pipeline backup line across the Gilyuy River in the Amur Region.
The Power of Siberia gas pipeline includes two double-string crossings across the Gilyuy River (Gilyuy 1 and Gilyui 2). The 511-meter pipeline of the backup line of the Gilyuy 1 crossing was laid in March of this year.
For laying the pipe into the design position in the underwater trench, 26 units of heavy machinery were involved: 18 pipe layers, 6 excavators and 2 bulldozers. Hydrohammer was used to develop trenches in the rock of the river bed. The contractor of the construction is Lengazspetsstroy.
After pneumatic testing, the backup line of the Gilyuy 1 crossing will be connected to the adjacent sections of the backup pipeline.
