Device STOPL-S-F1 is used for a medium temporary disconnection in pipeline with internal overpressure (or without overpressure) without a medium leakage. Device works on the following principle: stoppling head with a seal is inserted in pipeline through a bored hole, then it is shifed outside of a bored hole and subsequently compress the sealing in a way that all pipeline section is sealed and it generates a medium flow interruption. A device connection to the pipeline is made through special shaped piece - perpendicularly to the axis of pipeline.
