A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

In an aircraft duct formed with pipes connected in pairs via connectors in which the pipes are mounted with the possibility of axial displacement, there exists a risk that a pipe of the duct, with a dimension greater that the dimension of the nominal pipe, is mounted instead and in place of the latter. In this case, the wrongly mounted pipe would risk not having sufficient clearance in axial translation. In order to solve this problem, it is disclosed to equip one of the relevant connectors with an obstacle limiting the travel of the nominal pipe and preventing the mounting of a pipe with a greater dimension belonging to the duct. A method for assembling an aircraft portion is also proposed, in order to benefit from the particularities of the duct.

A magnetic filter 10 includes first and second separation chambers 10, 12. The separation chambers 10, 12 each have an inlet and an outlet, and the separation chambers 10, 12 are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement 28 connects both inlets to a single inlet pipe, and an outlet port arrangement 30 connects both outlets to a single outlet pipe.

A method of manufacturing a composite connector for a fluid transfer conduit is provided which comprises applying continuous fibre reinforcement, oriented at least partially circumferentially and pre-impregnated with a thermoplastic polymer to a tubular mould portion which extends substantially parallel to a central axis C; applying at least one further mould portion to form a complete mould in which the continuous fibre reinforcement is enclosed and injecting a thermoplastic polymer into the mould to form a connector with a tubular hub portion and a flange portion which extends from the hub portion at an angle to the central axis C. The tubular hub portion comprises a tubular seal section with an inner layer and an outer wherein the inner layer comprises the continuous fibre reinforcement and the outer layer comprises the injected thermoplastic polymer.

A telescoping joint is used to space out ends of a string and distribute the string weight between the tie-down locations. The joint can be compressed to reduce its length but has a locking mechanism that prevents extension under tensile loading. The seals in the joint provide a longer service life due to minimization of relative movement in the expansion joint components. The locking mechanism is preferably a ratchet system that uses a body lock ring that is enabled after breaking a shear pin.

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.

There is described a pipe connector for connecting first and second pipes slidably engageable one into the other, the pipe connector comprising: a side wall extending between a first end and a second end along a longitudinal axis and defining an interior space, the side wall being adapted to be inserted into a floor hole made into a floor; a floor flange extending laterally and outwardly from the first end of the side wall, the floor flange being adapted to rest on a floor surface when the side wall is inserted into the floor hole; and a guiding assembly secured to the side wall and comprising at least one resilient retaining finger for receiving the first pipe therebetween, the at least one resilient retaining finger being securable to the first pipe when the second pipe is engaged into the first pipe.

A tubular structure includes at least one exterior tube and at least one interior tube, at least a portion of the interior tube is disposed within the exterior tube. The tubular structure further includes at least one expansion joint provided between the exterior tube and the interior tube and the expansion joint allows lateral expansion or contraction of the exterior tube and the interior tube and maintains a pressure within the exterior and the interior tubes.
