FIELD: machine building.
SUBSTANCE: first pipe comprises insert section, which may be inserted into receiving part of the second pipe, besides an alignment device is provided to level angular position of both pipes relative to each other. In order to modify joint of two pipes maintaining angular alignment, on the assumption that suitability for use in complex systems of pipes with, for instance three-dimensional passage, is increased, the second alignment device is provided, which maintains longitudinal balance of pipes relative to each other. One pipe is fixed relative to the other pipe between minimum position and maximum position in direction of longitudinal axis with the possibility of displacement. The second alignment device provides for radial alignment of pipes relative to each other. Also one pipe may be fixed relative to the other pipe between the first and second positions of support with the possibility of slipping around longitudinal axis.
EFFECT: increased operational reliability.
