Remotely activated connection device for a spiral shoulder connection
The invention provides a remotely activated connecting device for connecting a wellhead and or Christmas tree positioned on a wellhead to a fracing tree that may comprise a collet system for selectively engaging and disengaging from a threaded, spiral, and or flange shoulder that may utilize hydraulics for same.
1. A method of connecting a connecting member to a male profile member, comprising:
providing one or more dog segments with a female profile;
holding said one or more dog segments out of engagement from said male profile member while engaging said connecting member with said male profile member;
releasing said one or more dog segments to allow engagement with said male profile member;
moving said one or more dog segments axially of said male profile member to allow said female profile of said one or more dog segments to engage said male profile member;
causing threads of said one or more dog segments to engage said male profile member;
securing said one or more dog segments in an engaged position with said connecting member thereby connecting said connecting member to said male profile member to create a seal;
wherein said one or more dog segments sit on an inclined shoulder of a window of a main body of said connecting member;
wherein said inclined shoulder has an angle which is greater than an engagement angle of threads on said male profile member; and
wherein said female profile of said one or more dog segments and said male profile member are flat top threads.
