Abstract: A method for determining an integrity of a connection includes applying a high-contrast material to a connection between a first tubular and a second tubular. A torque is applied to the first tubular. Applying the torque to the first tubular includes rotating the first tubular relative to the second tubular to establish the connection. A change in pattern of the high-contrast material in analyzed, while the torque is applied to the first tubular, using a strain detection tool that does not contact the connection. A strain at the connection is determined, based at least partially upon analyzing the change in pattern of the high-contrast material. An integrity of the connection is determined, based at least partially upon the strain.

Abstract: A tubular member connection system (11) includes a pin (15), external pin threads (17), and an annular pin lip (21) at a shoulder surface (20) of the pin. A box (27) has internal box threads (29) and an annular box lip (31) at an end surface of the box. The box threads are shaped to mate with the pin threads to releasably secure the pin to the box. A pin recess (22) is formed in an outer diameter surface of the pin, the pin recess extending in an axial direction from the pin lip. A pin key (59) is selectively fastenable within the pin recess, the pin key having pin teeth (69) on an outer edge of the pin key. The box teeth (33) are located in the box. The box teeth (33) selectively mate with the pin teeth (69) and resist rotation of the pin relative to the box.

Abstract: This invention builds up on technical features and on the industry experience with the use of Merlin® family connectors. In addition to friction, structural means utilized in order to transfer high torsional loads include: dog-clutch like teeth, fitted pins, keys, splines and interlocked thread systems, all used in isolation or in arbitrary combinations. Static and fatigue bending load capacities of the connectors remain high, while the axial load capacities may or may not be high, depending on the design requirements. Connectors according to this invention can be built as new, carefully optimized designs. In some cases upgrading existing Merlin® family connector designs to increase they torque transfer capacities may be also feasible.

Abstract: A broach-style anti-rotation device for connected tubular members (106; 108) is described. In embodiments, the broach tool (144) is inserted into a slot (118) in an outer diameter surface of the pin (102), and teeth (146) of the broach, which have successively greater height when moving from the front to the tail of the broach, cut a slot (160) in a surface of the box (104). Sidewalls of the broach and its teeth engage shoulders of each slot to prevent the rotation of the tubular members relative to each other.
