THEFT COHIBITION DEVICE, MINERAL EXTRACTION SYSTEM AND METHOD TO COHIN THEFT OF MINERAL EXTRACTION SYSTEM COMPONENTS

摘要

theft deterrent device, mineral extraction system and method for preventing theft of mineral extraction system components the present invention relates to a theft deterrent device, which can be used to prevent the theft of oil and gas equipment . for example, such an embodiment provides a nut (22, 72) and pin (74) assembly that includes an extended pin (74) and a standard hexagonal nut (22, 72). to prevent theft, the exemplary assembly includes an external sleeve (82) which is arranged around the nut (22, 72) and the pin (74) extended and which is free to rotate. as a result, the sleeve (82) prevents torque from being applied to the nut (22, 72) and also protects against the shear of the extended pin (92). the exemplary assembly also includes a tamper-resistant screw extending through the pin (92) and cooperating with a retaining ring (86) disposed above the nut (22, 72), to prevent removal of the outer sleeve (82).
