The Installation is intended for temporary tight shutdown of the repaired section of the pipeline on one or both sides from a product being under pressure (no more than 1.6 MPa) of a product (water, gas, oil).
The shutdown installation is entered into the pipeline through the shutoff valves established on the corresponding outlet with diameters of 150 or 200 mm which is previously welded on to the pipeline and through a temporary opening with a diameter of 132 or 170 mm. This installation is used in explosive zones of the class “2” according to GOST R 51330.9.

Attention: Use of the pipeline shutdown installation is possible only with branch pipes which are a part of the “KORT” for exact orientation of a locking- rotary part of the installation along the axis of the pipe.
