FIELD: machine building.SUBSTANCE: unit comprises a tubular body (11) with two end parts and contact surface (11b, 11c) located near at least one of end sections and able of contacting with the contact surface (2a, 4a) of the adjoining pipe (2, 4) in the pipeline (1). The contact surfaces (2a, 4a, 11b, 11c) are arranged so that the pipe unit (3) in connected state is movable in respect to the adjoining pipe (2, 4). The pipe unit (3) comprises a tubular flexible sealing block (8, 10) which at one end (8a, 10a) is rigidly fixed to the tubular body (11) and at the other end is fitted by a flange element (8b, 10b) being detachably coupled with the flange element (2b, 4b) of the adjoining pipe (2, 4) by a connection element (7, 9).EFFECT: improvement of the design.10 cl, 4 dwg |
