Patent ID: 8146959

Claim:
A pipe string component that connects an offshore platform with a sea bed, said pipe string component comprising: a threaded tubular connection, said threaded tubular connection including a male tubular element including a tapered male threading, and a female tubular element including a tapered female threading that cooperates with the male threading by makeup to produce a rigid mutual connection of the tubular elements, wherein: the male and female threadings each have a load flank extending substantially perpendicularly to a longitudinal axis of the male and female threadings, the male threading comprises a male stabbing flank disposed between a male thread crest and a male thread root, the female threading comprises a female stabbing flank disposed between a female thread crest and a female thread root, the male stabbing flank and the female stabbing flank each comprises: an intermediate region; a first neighboring region adjacent to a first end of the intermediate region; and a second neighboring region adjacent to a second end of the intermediate region, a contacting region between the male and female intermediate regions defines a male radial load transfer zone and a female radial load transfer zone, the male and female radial load transfer zones effect a radial interference between the male and female threadings upon makeup, the male and female radial load transfer zones are spaced apart from envelopes of thread roots of the male and female threadings by a first radial distance, and the contacting region between the male and female intermediate regions is substantially parallel to the longitudinal axis of the male and female threadings.
