titleOfInvention Tubular articles and the nipple made for the probing of hydrocarbon well and exploitation
abstract nullIt is an object of the invention to a kind of for implementing the assembly of nipple (1),Described nipple is for the probing of hydrocarbon well or exploitation,Described nipple includes the first tubular articles and second tubular articles with axis of rotation (10),Each tubular articles is furnished with a male type end (2) and a female end (3) respectively,In male type end (2) or female end (3), at least one is terminated by an end face,Described end face includes the first stop surface (60),When nipple is in tight condition,Described first stop surface can tightly hold contact by the second stop surface (70),Second stop surface itself is arranged on the other end on the convex shoulder implemented,In first stop surface (60) and the second stop surface (70), at least one has been dug a conduit (7),Described conduit thus define stopper area (12) in an outer stopper area (9) and,It is characterized in that,In tight condition,Outer stopper area (9) and interior stopper area (12) are non-coplanar,So that contact pressure P being applied to conduit (7) neighbouring (12a) of interior stopper area (12) Interior (a) Minima P more than or equal to the contact pressure being applied in outer stopper area (9) Outward (minima) 。
