A liquid loading device including a vertical lattice support structure, a platform coupled to the vertical lattice support structure, and a riser pipe located within the vertical lattice support structure and coupled to the vertical lattice support structure to substantially remain rotation free relative to the vertical lattice support structure. The device further includes a first rotatable joint located on a distal end of the riser pipe in which the first rotatable joint is operable to rotate relative to the riser pipe. The device further includes an arm extending from the platform and operable to be rotated relative to the platform. The device can also include a second rotatable joint coupled to the first rotatable joint through one or more rigid members, in which the second rotatable joint is operable to rotate relative to the platform. The device can further include an extension pipe extending from the second rotatable joint to a distal end of the arm.

A fracturing fluid delivery system is provided. In one embodiment, the system includes wellhead assemblies, a fracturing manifold trunk line, vertical branches extending upward from the fracturing manifold trunk line, and fluid conduits coupling the vertical branches in fluid communication with the wellhead assemblies. The fluid conduits may extend linearly from the vertical branches to the wellhead assemblies. Additional systems, devices, and methods are also disclosed.

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.

Air pipe for the intake tract of an internal combustion engine, for example a turbo engine, including a first pipe component composed of a first material and a second pipe component composed of a second material, the first material being more flexible than the second material.

A system for connecting and sealing flexible and rigid pipes under high pressure comprises a flexible pipe, rigid pipes, and transition connectors, wherein two ends of each transition connector are respectively connected with the flexible pipe and one rigid pipe, external sides of the flexible pipe and the transition connectors are coated with a rubber layer, and buckling sleeves are buckled on the rubber layer outside the transition connectors. Compared with the prior, the system can greatly improve the sealing performance of the flexible pipe and the rigid pipes, and thus can be used under high-low temperature and high-pressure atmospheres and be applied to air-conditioning pipes of new-energy vehicles.

An articulating flow line connector for connecting two sections or portions of a flow line, which may be a pressurized flow line. The connector may be configured to provide a sealed connection between the two sections or portions of the flow line, and may provide for a rotating or swiveling connection between the two sections. The articulating flow line connector may generally have a seal carrier ring arranged between two flow lines hubs. Each flow line hub may connect to an end of a flow line section. The seal carrier ring may be configured to provide both a sealing surface and at least one bearing surface. The seal carrier ring may have a sealing flange, a bearing flange, and a web portion extending between the flanges. The connector may additionally have a clamp arranged around or over the seal carrier ring and a portion of the two hubs.
