Weird I just said that a few hours ago when I saw them getting this tool out, while joking. Don’t they have better things to do. The Subsea FlexJoint® acts as a flexible coupling between the drilling riser and BOP stack. Specs: Water depths up to 12000 feet, Free angular rotation does not exceed ±10°, Working pressures do not exceed 6000 psi, Maximum axial tension requirement is 3500 kips All units share a common configuration consisting of a molded flex element with a customer specified upper connector flange housed in a forged steel body with a steel retainer ring. The flex element is protected from over-extension and tension loading by an internal wear ring. Replaceable upper and lower wear sleeves prevent abrasive damage to the ID of the FlexJoint®. FlexJoint® are constructed of a high-grade steels and selected nitrile elastomers that offer a high resistance to produced hydrocarbons and drilling fluids. Each Subsea FlexJoint® permits cocking displacements up to ±10 degrees. The FlexJoint® height range is from 44.17 to 67.05 inches. The overall height of the unit depends on the end connections selected as well as the pressure rating of the unit. The FlexJoint® housing diameter range is from 47 to 62inches …
