ABSTRACT:
Threaded pipe sections are connected to form a casing joint having proper sealing positioning at proper makeup torque. This improved connection includes a first pipe section having a standard API triangle mark at a predetermined position on its exterior surface for the proper axial engagement of the pin member with the coupling or box member. The box member is plated with a metal substantially comprising tin. A thread lubricant containing Teflon.TM. is applied to the threads of the pin and/or the threads of the box. The pin member and the box member are helically rotated together up to a minimum of an empirically predetermined torque range. While inexpensive, this improvement provides a simple method to determine visually on the rig floor, or at the pipe rack, whether the joint is properly made up to thereby provide effective gas sealing of the API buttress tapered threaded joint.
