    Abstract: A hanger system for use with a housing of a wellhead includes a hanger assembly. The hanger assembly includes a hanger having a respective radially-outer surface and a radially-extending surface, as well as a first annular wedge having a respective radially-outer surface with a first annular wedge surface texture. The radially-extending surface is configured to engage a shoulder of the housing of the wellhead while the hanger assembly is in a landed position within the housing of the wellhead, and the first annular wedge surface texture is configured to engage a respective-radially inner surface of the housing of the wellhead while the hanger assembly is in a sealed position within the housing of the wellhead.

    Abstract: A system includes a hanger running tool and a pressure port. The hanger running tool includes an upper body, a lower body disposed about the upper body, a first lock ring disposed between the upper body and the lower body, the first lock ring comprising a tapered top surface, a first push ring disposed between the upper body and the lower body, the first push ring comprising a tapered bottom surface that interfaces with the tapered top surface of the first lock ring, an upper piston disposed about the upper body, and a lower piston disposed about the first lock ring, the first push ring, and the lower body, extending axially downward. The pressure port is in fluid communication with a volume between the upper piston and the lower piston.

    Abstract: A connector assembly configured to join a first tubular member to a second tubular member of a mineral extraction system includes a first annular body, a second annular body, and at least one fastener extending through the first annular body and threadably coupled to the second annular body. A sealed space is defined between the at least one fastener and the first annular body. The connector assembly also includes a lock ring configured to contact the first annular body and the second annular body. A fluid pressure within the sealed space is configured to drive the first annular body and the second annular body toward one another, thereby driving the lock ring radially inwardly to engage the second tubular member.
