Metallic fluid tube

A fluid connection arrangement comprising a metallic fluid tube and further comprising:

• a further fluid-conducting component which abuts on a circumferential sealing geometry of the metallic fluid tube, wherein the further fluid-conducting component has a thread;
• and
• a threaded connector comprising a counter thread complementary to the thread of the further fluid-conducting component, wherein the threaded connector is connected to the further fluid-conducting component by a screw connection and is adapted to press the further fluid-conducting component onto the circumferential sealing geometry of the metallic fluid tube, so that a press connection is obtained between the circumferential sealing geometry of the metallic fluid tube and the further fluid-conducting component, and thereby a fluid-tight press connection is formed between the metallic fluid tube and the further fluid-conducting component,
• the metallic fluid tube comprising:
• a metallic tube wall comprising a tube wall inner side which delimits an interior space of the metallic fluid tube and a tube wall outer side which faces away from the interior space of the metallic fluid tube and faces an exterior area of the metallic fluid tube,
• wherein the metallic tube wall comprises a tube end with a tube opening which connects the interior space of the metallic fluid tube with the exterior area of the metallic fluid tube,
• wherein the metallic tube wall has an elevation which runs around the tube wall outer side and is arranged such that the elevation is spaced apart from the tube end,
• wherein the tube wall outer side has the circumferential sealing geometry which is adapted to provide a fluid-tight connection between the metallic fluid tube and the further fluid-conducting component of the fluid connection arrangement, and wherein the circumferential sealing geometry extends on the tube wall outer side from the elevation to the tube end,
• wherein the circumferential sealing geometry has turning grooves which extend along a groove extension direction, wherein the groove extension direction runs transversely to a longitudinal extension direction of the metallic fluid tube,
• wherein the turning grooves run spirally around the circumferential sealing geometry from the tube end in a direction of the elevation, wherein the turning grooves which encircle the circumferential sealing geometry are arranged spaced apart from each other along the longitudinal extension direction of the metallic fluid tube,
• wherein the turning grooves are formed as raised grooves on the circumferential sealing geometry to achieve a high surface pressure, and
• wherein the turning grooves are arranged on an entirety of the circumferential sealing geometry, and wherein the turning grooves are arranged at least in sections on the elevation.
