Abstract
The invention relates to a device for connecting pipe ends (80, 82) of double-walled pipes (72, 74) for angular compensation and for length compensation of the relative movements of the double-walled pipes (72, 74) relative to a double-walled connector (10). On the double-walled connector (10), there are arranged concentrically with respect to one another first and second ball heads (20, 26). These are each sealingly engaged over by ball cages (52, 54). The ball cages (52, 54) are formed on double-walled attachments (46) of the double-walled pipe ends (80, 82). The sealing function for double-walled angular compensation and double-walled length compensation are configured so as to be decoupled from one another, and are therefore optimized, in the case of the device proposed according to the invention.
