Device for gas-tight connection between a connection surface and a reference surface

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.
