FIELD: machine building.
SUBSTANCE: invention relates to pipe connection system (1) for connection of two pipe ends (2, 3), in particular, two pipe ends located in exhaust path of internal combustion engine, including two axially oriented towards each other and/or spaced from each other end (2, 3) of pipes, which on their outer circumferential surface have each circularly enveloping its convex spherical section (7), wherein these two ends of pipes with their convex spherical sections (7) are placed in connecting pipe (8), covering these ends (2, 3) of pipes on outer side on the overlapping section, so that convex spherical sections (7) adjoin each, radially rounding it, in area (16) adjoining spherical section to inner wall (9) of connecting pipe (8). According to the invention, convex spherical areas (7) in areas (16) of adjoining spherical sections adjoin each along circumferential line (10) and thus with linear adjacency along circumference to inner wall (9) of connecting pipe (8).
EFFECT: technical result is wider functional capabilities.
