A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange is of generally annular disc shape with an inner surface, an opposing outer surface, an inner edge, and a radially-spaced outer edge. Each pipe flange includes an annular outer recess formed on the outer surface adjacent to the inner edge. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. Each liner flange may be positioned within the outer recess of a successive one of the pipe flanges.

A rotatable flanged component is adapted for assembly into a flow line of a high-pressure fluid transportation system. The rotatable flanged component comprises a body and a conduit. The body has at least two ends. The conduit extends between the ends. The rotatable component also has a flange and a union face at each of the ends. The flanges and union faces are adapted to provide a flange union between the component and other flowline components at each the body end. At least one of the flanges is a rotatable flange. The rotatable flange has a central opening and a plurality of holes. The holes are adapted to accommodate threaded connectors for loading the flange with an axial force. The flange is mounted on the body end through the central opening for rotation and for transmission of the axial force to the body end.

A telescoping fluid coupling (10,110) is provided for use with a fluid flow device (12) and includes a coupling body (14,114) having a fluid port (16,116) extending along a longitudinal axis (18,118). A retainer (20,120) is fixed to the body (14,114) and includes a retaining shoulder (26,126). A flange (22,122) is mounted to the fluid port (16,116) and includes a radially inwardly facing guide surface (36,136) that surrounds a mount surface (24,124) and extends longitudinally along the axis (18,118) to provide guided, sliding translation of the guide surface (36,136) relative to the mount surface (24,124) along the axis (18,118). The flange (22,122) further includes a stop shoulder (38,138) to engage the retaining shoulder (26,126) to limit the translation of the flange (22,122) along the axis (18,128).

A flange for an electrical bushing is specified, comprising a lower part and an upper part configured to be mechanically affixed to one another, wherein the lower part and the upper part are arranged one above the other in an axial direction of the flange, and one of the lower part and the upper part surrounds a portion of the other one of the lower part and the upper part at least in regions in a radial direction, thereby forming a positive connection against relative movement of the upper part with respect to the lower part in a non-axial direction of the flange.

Furthermore, an electrical bushing is specified.
