Abstract
A tubular member includes a pin end terminating in a pin end face, an external thread profile defined on an outer circumference of the pin end and terminating at a thread termination location axially offset from the pin end face, and an axial extension provided on the pin end and extending axially from the thread termination location to the pin end face, the axial extension defining a gauge surface for obtaining diameter measurements of the pin end. An angle of the gauge surface aligns with an angle of a root plane provided by the external thread profile.
Claims19
A tubular member, comprising:
- a pin end terminating in a pin end face;
- an external thread profile defined on an outer circumference of the pin end and terminating at a thread termination location axially offset from the pin end face;
- and
- an axial extension provided on the pin end and extending axially from the thread termination location to the pin end face, the axial extension defining a gauge surface for obtaining diameter measurements of the pin end,
- wherein an angle of the gauge surface aligns with an angle of a root plane provided by the external thread profile.
A method of coupling a tubular member to a box end, comprising:
- inserting a pin end of the tubular member into the box end, the box end defining an internal thread profile and the pin end terminating in a pin end face and including:
- an external thread profile defined on an outer circumference of the pin end and terminating at a thread termination location axially offset from the pin end face;
- and
- an axial extension provided on the pin end and extending axially from the thread termination location to the pin end face, the axial extension defining a gauge surface for obtaining diameter measurements of the pin end, wherein an angle of the gauge surface aligns with an angle of a root plane provided by the external thread profile;
- and
- rotating one of the tubular and the box end relative to the other of the tubular and the box end and thereby engaging the internal and external thread profiles and advancing the pin end into the box end.
A method of measuring a diameter of a tubular member, comprising:
- positioning a gauge measurement device adjacent a pin end of the tubular member, the pin end terminating in a pin end face and including:
- an external thread profile defined on an outer circumference of the pin end and terminating at a thread termination location axially offset from the pin end face;
- and
- an axial extension provided on the pin end and extending axially from the thread termination location to the pin end face and thereby defining a gauge surface, wherein an angle of the gauge surface aligns with an angle of a root plane provided by the external thread profile;
- arranging the gauge measurement device on the pin end by positioning arms of the gauge measurement at opposite angular locations about an outer circumference of the gauge surface;
- and
- adjusting a position of the arms to come into contact with the gauge surface and thereby obtaining a measurement of the diameter of the pin end at the gauge surface.
