Weldless surface casing connection system
Simplify wellhead installation without welding or special tooling.
Designed for completions applications, FlangeLock low-torque wellhead connectors combine the fast makeup and low-torque requirement of FastLock quick wellhead connectors with the inherent low cost of flange connections.
Designed using 3D finite element analysis (FEA), the FlangeLock connector meets the requirements of ASME Section VIII, Division 2 and API 6A specifications. Laboratory tests were performed to verify these results.
13 5/8-in, 5,000-psi and 20 3/4-in, 3,000-psi connectors have been strain-gauged and tested in various configurations, including blind flanges and integral connections on tree blocks and spools. An 11-in, 5,000-psi version with a CF gasket has successfully completed fire testing per API 6FB Part II.
