Torque/Flow Thru Knuckle Joint

The Wellpro Group Torque/Flow Thru Knuckle Joint provides additional flexibility allowing the BHA to pass unrestricted through/over tubing crossovers, WEG’s, profiles, high deviation wells and other points where a rigid BHA may encounter difficulty.  The tool also has a full 15-degree angular deviation and internal pressure sealing.


The ball and socket of the knuckle have keys that prevent rotation whilst withstanding torque, while still allowing full angular movement.  The tool can also be used in certain fishing applications to help centralise or de-centralise the fishing string.
