摘要： A threaded tubular connection comprises a first tubular component and a second tubular component. The first tubular component includes a female portion defined on an interior surface of the first tubular component. The female portion includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder. The second tubular component includes a male portion defined on an exterior surface of the second tubular component. The male portion is to be inserted into the female portion, and includes an inner threaded portion and an outer threaded portion which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder. The second shoulder is to abut the first shoulder once the male portion is connected to the female portion.

摘要： A threaded tubular connection including a first tube and a second tube is provided. The first tube includes a pin member which extends from an end of a main body of the first tube to a terminal end of the first tube. The second tube includes a box member which extends from an end of a main body of the second tube to a terminal end of the second tube. A cross-sectional area of a pin critical cross-section is within approximately ±5% of cross-sectional area of a box critical cross-section of the box member. The cross-sectional areas of each of the pin and box critical cross-sections are within approximately ±5% of the sum of the cross-sectional areas of a box intermediate critical cross-section of the box member and a pin intermediate critical cross-section of the pin member.

In a made-up state, a first seal surface on the pin engages a second seal surface on the box in a radial direction so as to form an off-center fluid tight seal that extends in an axial direction of the threaded tubular connection.

摘要： A threaded tubular connection comprises a male tubular element comprising a male threaded portion and a female tubular element comprising a female threaded portion which cooperates by screwing with the male threaded portion.
In accordance with the invention, the threaded connection comprises at least one transfer zone which can transfer bending loads between said elements and which is axially spaced from said threaded portions, in which the male and female elements have an undulating surface and a smooth surface facing each other, the undulating surface (5) defining a series of rounded annular ribs (7) which come into contact with the smooth surface with a radial interference fit.

摘要： A coupled version of a threaded connection (10) includes first threads (16, 38) and second threads, (20, 34) on both elongate tubulars (14, 30) and a coupling (45). An integral joint version (50) preferably includes a first and second tapered threads (58, 60) on each of the connected tubular bodies (54, 56). The coupling preferably includes a dope entrapment cavity in one of the connected tubulars between the first and second threads. A tapered metal seal surface is provided preferably between the first and second threads. The second thread in a preferred embodiment is a hook thread with a negative rake angle. In another embodiment, the pin ends of a coupled connection may engage, with seals provided between the first and second threads on each tubular.
