Beschreibung
Zusammenfassung:	Threaded tubular connection (10) comprising a tubular female end (20) extending from a main body (21) of a first tubular member (22), and a tubular male end (30) extending from a main body (31) of a second tubular member (32), such that the tubular male end (30) comprises a first machined inner surface (68) close to the male free end (35) and a second machined inner cylindrical surface (70) above a threaded portion of the male end such that a second inner diameter (JIP2) of the second machined inner cylindrical surface (70) is smaller than a first inner diameter (JIP) of the first machined inner surface (68).
