FIELD: machine building.
SUBSTANCE: group of inventions refers to connection of pipelines. In design of pipeline connection, on one of its end parts there is external conical thread, and on its other end part there is connection device that is connected to the connection part. External conical thread has such length that at the end moment of screwing that thread into internal conical thread that is formed in end head, the external conical thread enters it throughout the whole length, and therefore the sealing effect by means of a sealing element is achieved. Version of design of pipeline connection is described.
EFFECT: higher connection efficiency.
