Abstract:
A threaded tubular connection comprises a first tubular (12) component and a second tubular component (14). The first tubular component (12) includes a female portion (10) defined on an interior surface of the first tubular component. The female portion includes an inner threaded portion (16d) and an outer threaded portion (16b) which are offset radially with respect to a longitudinal axis of the first tubular component by a first shoulder (26). The second tubular component (14) includes a male portion (18) 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 (18d) and an outer threaded portion (18b) which are offset radially with respect to a longitudinal axis of the second tubular component by a second shoulder (28). The second shoulder is to abut the first shoulder once the male portion is connected to the female portion. The threaded tubular connection comprises an inner short length fluid tight seal.
