Abstract

Jointed pipe connections are used for axial, angular and lateral oscillation decoupling of tubular pipe segments. A jointed pipe provided for connection with a first pipe segment has an annular fold, against which a pressed wire ring rests respectively on the right and left sides. The pressed wire rings are enclosed by an annular cuff which, by means of a pipe socket, forms a cuff pipe used for a connection with a second pipe segment. This prior art arrangement permits only a limited annular movement. The permitted pivot angle diminishes as pipe diameter increases. In accordance with the invention, a plurality of joint areas are provided. The jointed pipe (3) located on the inside has annular folds (4) at both ends. Annular pads (5) rest against these and are enclosed in pairs by annular cuffs (6). The cuffs (6) have pipe sockets (6a) by means of which they are connected with the pipe segments. The cuffs (6) are connected in a gas-tight manner by a sealing bellows (9, 29).
