1. A device for gas-tight connection, comprising:
a first connection point with a terminal surface;
a second connection point with a stationary, predetermined reference surface of a pipe flange connection, which is arranged relative to the terminal surface by an offset angle which is configured to be compensated for by angular offset compensation means; and
a flanged disc unit,
wherein the first connection point comprises a central ball-and-socket joint arrangement as angular misalignment compensation means,
wherein the central ball-and-socket joint arrangement comprises a tube section with a convex distal end region configured to interact in an articulated manner with a concave annular region, corresponding thereto, of the flanged disc unit, and
wherein a side surface region of the flanged disc unit comprises at least one adjusting screw configured to adapt to the offset angle so as to adjust a local distance to a counter-disc fixedly fastened coaxially to a pipe section adjacent to the convex distal end region, and
wherein the flanged disc unit comprises two disc parts that come into contact with one another in a planar manner and together form the concave annular region on an inner radial side, and
wherein at least one spherical recess is formed between the two disc parts of the flanged disc unit, which recess, together with a spherical head of an associated at least one adjusting screw, forms an associated peripheral ball joint.
