FIELD: oil and gas industry.
SUBSTANCE: invention is related to pipeline transport of oil and gas chemical products, in particular, to devices and facilities to control technical condition of the pipeline. The device consists of two branches installed at the main line, two shutoff gates installed at the branches, two cut-off valves and a pipe made of pipe sections by welding as per the main line assembly technology, ends of this pipe are bended at straight angle in one direction, the pipe ends are connected to both outputs of the cut-off valves and tied up by a stabilising shape.
EFFECT: reduction of down-time during control measures and improvement of measurement accuracy.
