摘要： In accordance with embodiments of the present disclosure, an improved anti-rotation device for preventing rotation of two joined tubular members of a connector assembly is provided. The connector assembly includes a first threaded portion connected to a second threaded portion. The anti-rotation device includes at least one self-tapping screw installed in an associated threaded bore formed in and tangential to a flange of the second threaded portion. When installed, the at least one self-tapping screw engages a shoulder of the first threaded portion. A partial thread is formed in the shoulder of the first threaded portion by the at least one self-tapping screw, which forms a shear-resistive force that prevents rotation of the first threaded portion relative to the second threaded portion, and thus prevents rotation of one tubular member relative to the other.

摘要： In accordance with embodiments of the present disclosure, a seal assembly for sealing and locking a casing hanger to a wellhead includes a lower seal body, an upper seal body connected to the lower seal body, an inner lock ring disposed between the upper seal body and the lower seal body, an external lock ring engaging the upper seal body, and an energizing ring. The lower seal body is structured and arranged to form a seal with the casing hanger and the wellhead. The upper seal body includes a load portion that overhangs a load shoulder of the casing hanger. At least a portion of the energizing ring is disposed within an inner groove disposed within the upper seal body. The energizing ring locks the inner lock ring into forcible engagement with the casing hanger, and locks the external lock ring into engagement with the wellhead.

摘要： A high capacity universal connector for use in connecting tubular members and a method for sealing the tubular members is provided. First and second tubular members are provided which each have ends that are brought into face-to-face engagement by a connector. A metal sealing element seals against conical surfaces at the ends of the first and second tubular members and enables the entire surface of the end of one tubular member to be bought into engagement with the surface of the end of the other tubular member so as to improve the bending and compression capacity of the assembly comprising the tubular members and the metal sealing element. A metal sealing ring for use in this assembly is also provided, along with a gasket retention assembly.
