FlangeLock
Low-torque wellhead connector
Fast makeup and low torque requirement
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.
- Metal-to-metal sealing. FlangeLock connector uses the same metal-to-metal sealing CF gasket as our FastLock connector.
- Field ready. FlangeLock connector attaches directly to the FastLock connector hub.
- Smaller OD. Flange diameter of the connector is the same as the diameter of the hub ,which is significantly smaller in diameter than the equivalent API flange.
- Low torque. Larger number of smaller cap screws is used on the FlangeLock connector to keep the makeup torque within the range of lightweight torque wrenches.
Specifications
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.
