BALL JOINT PIPE CONNECTION

摘要

A pipe connection includes a ball joint having shell parts and pipe connection elements at the ends of the shell parts which face away from each other are to be connected to a respective pipe section. The shell parts surround one another in a contacting manner and define a respective longitudinal centre line; they are rotatable relative to one another between an aligned position, in which the longitudinal centre lines coincide, and a rotated position, in which the longitudinal centre lines form an angle which differs from zero. The shell parts together enclose an axial passage which extends between the ends of the shell parts. A sealing element is provided between the outermost and innermost shell part. A lining extends between the outermost shell part and the corresponding pipe connection element. The inner lining surface has a curvature corresponding to that of the outer surface of the innermost shell part.

1. Pipe connection, comprising a ball joint (1) having shell parts (3, 4), pipe connection means (20, 21) at the ends of the shell parts (3, 4) which face away from each other and which are to be connected to a respective pipe section, which shell parts (3, 4) surround one another in a contacting manner, each define a respective longitudinal centre line and are rotatable in relation to one another between an aligned position, in which the longitudinal centre lines coincide, and a rotated position, in which the longitudinal centre lines form an angle with one another which differs from zero, wherein the shell parts (3, 4) together enclose an axial passage which extends between the ends of the shell parts (3, 4), a sealing element (6) between the outermost shell part (4) and the innermost shell part (3), and a lining which extends between the outermost shell part (4) and the corresponding pipe connection means (21), characterized in that the inner lining surface (14) of the lining (13) has a curvature corresponding to the curvature of the outer surface (5) of the innermost shell part (3) and in that said inner lining surface (14) and said outer surface (5) lie entirely free in relation to one another.
