Sealing device and method for the production thereof and pipeline system

A pipeline system comprising,

• a pipeline arrangement and a sealing device for sealing the pipeline arrangement,
• the pipeline arrangement having two pipeline units with a pipeline central axis and a clamping device,
• wherein each pipeline unit comprises:
• a pipeline having a pipeline outer surface,
• a pipeline end face,
• a pipeline outer diameter, and
• a pipe socket with a pipe socket inner diameter, wherein the pipe socket is provided with a flange section having a flange section end face and a pipe section having a pipe section inner surface,
• wherein the clamping device clamps the flange sections of the pipe sockets of the two pipeline units axially to each other,
• wherein the sealing device has in a position of use, a seal located axially between the flange section end faces of the pipe sockets,
• wherein the sealing device has a data medium assigned to the seal and comprising an electronic data memory to which seal-specific information can be or is written,
• wherein the seal of the sealing device has a sealing outer surface, which extends radially around a sealing device central axis, on which a seal section is arranged, and wherein the seal section comprises the data medium,
• wherein the sealing device forms a transition between the pipeline units which are clamped to one another,
• wherein the sealing device comprises a seal insert that defines an axial minimum distance between the two pipeline units, and
• wherein the transition between the pipeline units is defined by clamping forces which are set by the seal insert such that a curvature with respect to a pipeline inner diameter forms an obtuse angle.
