The Flex Joint connects the marine riser to the subsea wellhead or blowout preventer, allowing controlled angular deflection to compensate for vessel motion, wave action, and currents while maintaining pressure integrity.
Typical materials include high-strength alloy steel for the housing and elastomeric compounds such as nitrile rubber or polyurethane for the flexible elements.
Reference ranges include nominal diameter 50-600 mm, operating pressure 1.0-1.6 MPa, angular deflection ±10° to ±20°, and temperature -20°C to 80°C. These must be verified for the specific model.
Consult the legal manufacturer or supplier to confirm model-specific values, standards, and compliance with your operational requirements. Do not rely solely on directory reference ranges.
