A high efficiency take-off fitting allows conditioned air from a rectangular cross-section main duct to be smoothly transferred into a circular cross-section branch duct.

Technology is provided for a fluid conduit assembly for connecting orthogonally oriented connections. The assembly includes a first tube arcuately extending from a first proximal end portion to a first distal end portion. The first proximal end portion includes a first fitting connectable to a first fluid connection. A second tube arcuately extends from a second proximal end portion to a second distal end portion. The second proximal end portion includes a second fitting connectable to a second fluid connection that is orthogonally oriented with respect to the first fluid connection. A coupling connects the first distal end portion and the second distal end portion. The first rigid tube is rotatably positionable with respect to the first fluid connection whereby a first distal axis and a second distal axis are substantially coaxially aligned when the first fitting and second fitting are connected to the first and second fluid connections, respectively.

A pig trap of this disclosure may include one or more injectors or nozzles located along a sidewall of the barrel and oriented to deliver a jet of fluid toward a back side of a vertical member of a pig or tool. The nozzle may be part of an assembly that includes a longitudinally extending pipe having a flat-profile flange at an inlet end, a curved-profile flange at the nozzle end, and a bend in between the two ends. When the assembly is installed in a sidewall opening of a pig trap, the nozzle delivers a jet of fluid toward the back side of a vertical member of the pig. A leak path may be provided through flanges or formed between the sidewall opening and a periphery of the curved-profile flange. Launch forces of more than 10 to 15 times that of a conventional launcher may be achieved.

Apparatuses, systems, and methods are provided for generating power. A pipe having an input flow is coupleable to an input section configured to receive at least a portion of the input flow. A generation section is coupleable to the input section and includes a pipe section to carry the at least a portion of the input flow, a turbine coupleable to the pipe section and configured to capture energy from the at least a portion of input flow carried by the pipe section, and a generator coupleable to the turbine and configured to generate power from the energy captured by the turbine. An output section may be open ended and configured to provide a discharge for the generation section away from the pipe.

A flange structure for connecting together two members each having a flow path with different angles which can control an increase in flow resistance and can realize easy and stable manufacture can include a first member and a second member connected to each other through a flange. A central axis of a flow path of the second member can be slanted at a first angle with respect to a central axis of a flow path of the first member. The flow path of the first member and the flow path of the second member are allowed to communicate with each other by an in-flange flow path formed in the flange, and a second angle constituted of an acute angle between a central axis of the in-flange flow path and the central axis of the flow path of the first member is smaller than the first angle.

The first rigid tube is rotatably positionable with respect to the first fluid connection whereby a first distal axis and a second distal axis are substantially coaxially aligned when the first fitting and second fitting are connected to the first and second fluid connections, respectively.

An internal boss can have an outer side surface shaped to match the bored opening of the DWV pipe, an inner side surface shaped to align with an interior pipe surface of the sanitary Tee or Wye fitting component, and an internal face surface of the boss extending between the side surfaces and shaped to align with an interior pipe surface of the DWV pipe when welded thereto. Snap-fit wings can hold the interior face surface of the sanitary Tee or Wye fitting component against an exterior face surface of the DWV pipe while the fitting component and DWV pipe are homogeneously weldable into a single DWV fitting using a solvent mixture including a common plastic material. Related methods and single homogeneous fittings are also provided.

A snap fitting far use in plumbing is provided. The snap fitting includes a main body formed of plastic and shaped to extend partially around a cylindrical pipe to snap over the pipe and an inset for extending from an interior side of the main body into a hole in the cylindrical pipe.

A sensor supply tube assembly is provided for disposition within a compressor outlet through which a main flowpath is defined and a sensor port transversely coupled to the compressor outlet. The sensor supply tube assembly includes first and second tubes. The first tube is formed to direct main flowpath fluid from the compressor outlet and through a portion of the sensor port and includes first and second ends disposed within the sensor port and the compressor outlet, respectively, and a curved section interposed between the first and second ends. The second tube includes a sleeve tightly fittable between the first end and the sensor port and a base. The base has an exterior surface from which the sleeve extends and which is disposed and configured to non-rotatably abut with an interior surface of the compressor outlet.
