Abstract (en)
[origin: DE19836088C1] The invention relates to a pipe connection comprising a sleeve element (7). Said sleeve element comprises an inner threaded section (8) which axially extends inward from the end. A non-threaded section (10) connects to the inner threaded section. The inventive pipe connection also comprises a pin element (18) which comprises a threaded section (19) constructed to be complementary to the sleeve element (7). A non-threaded section (23) which extends up to the front end connects to said threaded section (19). The non-threaded sections (10, 23) come in contact with one another when they are screwed in and they form a metallic sealing system. The sealing system is provided with two axially interspaced contact zones of which at least one comprises geometrically different cross section contours.
