FlexJoint™ Products

BOPStackSubseaFlexJointOil States FlexJoint products have been used by the offshore industry in riser, pipeline and mooring systems since 1976 and are an enabling technology for most drilling and production platforms worldwide. Our flexible joint technology provided the critical seal in capping the Macondo well in 2010. It withstood over-rotation and extreme well bore temperatures and pressures for an extended duration. This sealing technology is only available with the Oil States FlexJoint assembly.

Diverter Flexible Joint Assemblies

Key Features

  • Compressive loadings of up to 20 kips.
  • Angular rotation of up to ±15°.
  • Working pressures do not exceed 500 psi.
  • Axial tension requirements of 500 to 4,000 kips.

Applications

  • The diverter flexible joint is installed at the top of the riser below the diverter housing where it will encounter significant compression.
  • Mobile offshore drilling units.
  • Drilling riser systems.
