A fracturing manifold system includes a first manifold assembly in a side-by-side arrangement with a second manifold assembly. The first manifold assembly includes a plurality of first junctions, each having multiple inlet ports facing a first side of the fracturing manifold system. The second manifold assembly includes a plurality of second junction, each having multiple inlet ports facing a second side of the fracturing manifold assembly. Inlet ports on a single junction may be angled relative to each. The inlet ports may also be angled relative to a manifold flow path.

A coupling for conveying a fluid between a stationary part and a rotatable part having confronting ports centered on a rotation axis of the rotatable part has an axially extending tube fixed in the port of one of the parts and extending toward the port of the other of the parts and a control element axially slidable on the tube. The one part, the tube, and the control element form an annular chamber around the tube pressurizable for axially shifting the control element. A first slide ring is connected to the control element and carries a seal ring turned toward the port of the other part, and a second ring on the other part at the port thereof axially bears on the first slide ring so that pressurization of chamber presses the slide rings axially against each other.

A fracturing system is provided. In one embodiment, the fracturing system includes a fracturing manifold for routing fracturing fluid to multiple wells. The fracturing manifold can be coupled via fluid conduits to fracturing trees installed at the wells. In some cases, each fracturing tree that is coupled to the fracturing manifold is coupled by at least one rigid fluid conduit. The fracturing manifold can include a trunk line that provides fracturing fluid to multiple outlet branches, which can include valves for controlling flow of fracturing fluid to wells downstream of the valves. Additional systems, devices, and methods are also disclosed.

An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.

A pipe connection compensation device by magnetic fluid sealing comprising a compensation pipe, sealed end cap, coil, annular permanent magnet and tightening rod is provided, designed and configured in a novel manner to ensure the pipe connection compensation device by magnetic fluid sealing achieves a better sealing effect.

A pipeline telescopic joint configured to compensate for dimensional changes has: a first pipe section having a first diameter; a second pipe section having a second diameter smaller than the first diameter is slidingly coupled to the first pipe section; an end assembly, which is fixed to the second pipe section an annular seat bounded by two facing cylindrical faces; and an annular gasket, which is housed within the annular seat and has a polymeric casing and a spring housed within the polymeric casing, wherein the polymeric casing is in contact with the cylindrical faces.

A tube assembly according to an exemplary aspect of the present disclosure includes, among other things, an adjustable joint having a flange axially movable along an end fitting having a male/female connection with a mating part. The flange is threadably engaged with the end fitting to provide for the adjustment of the position of the flange along the end fitting. The adjustable joint accommodates thermal effects and tolerance stack-up in a male/female connection.

A fracturing system can include a fracturing manifold coupled to a plurality of fracturing trees. The fracturing manifold may include adjustment joints that enable adjustment of the length of the fracturing manifold. The fracturing manifold can also include pivot joints that allow angular displacement of portions of the fracturing manifold with respect to other portions. The adjustment and pivot joints can accommodate spacing and elevation differences between the fracturing trees.
