Abstract: A misalignment ball joint fitting includes first and second body portion coupled together and having spherical inner surfaces. A ball secured inside the body portions has a passage therein. The passage has a funnel shaped portion in a first end portion of the ball. The ball is allowed to at least partially rotate when secured inside the first and second body portions. A guide sleeve is coupled to the first body portion. The guide sleeve is coaxial with the ball passage. A recess is in an inner surface of the ball near a center of the ball. An end of the guide sleeve extends into at least a portion of the recess when the ball is in a neutral position with walls of the passage in the ball parallel to walls of the guide sleeve.

Abstract: A body includes two separate openings on a first side of the body that correspond to separate passages that converge to a common passage. An opening on a second side of the body couples to the common passage. A bore in the body is concentric with the common passage. A diverter has at least a part of the diverter in both the bore and the common passage. A tubular portion of the diverter has an open end in fluid communication with the common passage. One or more seals are positioned circumferentially around the part of the diverter located in the bore. The diverter is selectively rotated with the drive mechanism during use to align a diverter wall opening with a selected separate passage such that an object moving from the common passage through the tubular portion of the diverter is directed into the selected separate passage during use.

Abstract: A fitting includes a body having at least two portions coupled together to form a body having a passage through the body. The passage allows at least a portion of a conduit to be located at least substantially lengthwise within the body. First and second ports are located on the body and are in fluid communication with the passage. A first seal is located on the passage wall between a first end of the body and the first port. A second seal is located on the passage wall between the first port and the second port. A translatable ring is located on the passage wall between the first and second seals. The ring moves along the passage wall when the first seal is activated so that the second seal is activated. The ring includes an opening proximate the first port to provide access to the conduit from the first port. The first and second seals provide a seal in the passage.

Abstract: A device includes a stem hub attached to a fitting body. A rotatable stem is located at least partially within the stem hub. Rotation of the rotatable stem operates a blocking element located in the fitting body. In an embodiment, an upper stem is coupled to a first end portion of the rotatable stem so that rotation of the upper stem rotates the rotatable stem. A metal seal is located on the stem hub. A portion of the upper stem presses the metal seal between the upper stem and the stem hub when the upper stem is moved towards the stem hub. An operating mechanism moves the upper stem towards the stem hub and away from the stem hub. The upper stem is moved by the operating mechanism in a direction normal to the rotational axis of the rotatable stem and the upper stem.

Abstract: A subsea fitting is disclosed. The subsea fitting includes a body. The fitting includes at least two passages through the body. The passages are in fluid communication within the body. A diverter is located in at least one of the passages. The diverter may be movable between an open position and a closed position. In the open position, the diverter allows open flow between two of the passages. In the closed position, the diverter inhibits flow between the two passages.

Abstract: A piggable pipeline system is disclosed. One or more pig launcher/receivers may be coupled to a pipeline. At least one fitting may be coupled to the pipeline.

The passage allows at least a portion of a conduit to be located at least substantially lengthwise within the body. First and second ports are located on the body and are in fluid communication with the passage. A first seal is located on the passage wall between a first end of the body and the ports. A second seal is located on the passage wall between a second end of the body and the ports. The first and second seals provide a seal between the outside wall of the conduit and the inside wall of the body. A channel is formed in the body to allow fluid flow at least partially circumferentially in the body between the first port and the second port.
