A flange fitting for attaching to double wall tubes includes a fitting center port, a plurality of fitting mounts, inner and outer seal surfaces, fluid communication ports, and a connections surface. The fitting center port extends through the fitting for passing a primary fluid flow. The fitting mounts are spaced radially away from the center port for receiving fasteners. The inner and outer seal surfaces are predominantly flat. The fluid communication ports for pass a secondary fluid flow and fluid communication ports extend through the fitting from between the inner and outer seal surfaces to the connection surface between the inner sleeve connection and the outer connection. The connection surface is on a side of the fitting opposing the seal surfaces. The connection surface includes an inner sleeve connection and an outer connection.

Double wall tube bolted flange fitting

A drainage assembly () includes a first segment (A) with a first inner tube (A) defining a first inner tube passage (A), a first outer tube (A) concentrically disposed around the first inner tube (A) and defining a first outer tube passage (A), and a first fitting (A) disposed on an end of the first segment (A). The first fitting (A) has a first inner passage (A) in fluid communication with the first inner tube passage (A) and a first outer passage (A) in fluid communication with the first outer tube passage (A). A plate () is positioned adjacent the first fitting (A). The plate () has a second inner passage () in fluid communication with the first inner passage (A) on one side, and a second outer passage () in fluid communication with the first outer passage (A) on the one side. Also included is a drainage line () in fluid communication with the first outer tube passage (A).

Double walled tube drainage system

In various embodiments, a double wall pipe assembly may comprise a coupling, a first pipe, a second pipe, a first piloted flange and second piloted flange. The coupling may define a minor diameter receivable slot and a major diameter receivable slot. The double wall pipe may be configured to conduct a fluid. The double wall pipe operatively coupled to the coupling. The double wall pipe may comprise a first pipe, a second pipe, a first piloted flange, and a second piloted flange. The second pipe may be sleeved over the first pipe. The first piloted flange may be operatively coupled to the first pipe. The first piloted flange may be installable in the minor diameter receivable slot. The second piloted flange may be coupled to the second pipe. The second piloted flange may be installable in the major diameter receivable slot.

Doubled wall pipe flange and coupling configuration

A V-band clamp includes a V-band segment that has a V-groove and is configured to generally circumscribe a flange of a first component and a flange of a second component. The V-band segment has a coupling element that is configured to couple the V-band clamp to a third component. The V-band clamp also has a latch disposed on the V-band segment that is configured to tighten the V-band clamp about the flanges.

V-band clamp with integral mount plate

A double wall tube assembly includes an inner tube extending in an axial direction between two opposed ends of the inner tube. A sleeve fitting is mounted to one end of the inner tube. An outer tube outboard of the inner tube extends in the axial direction between two opposed ends of the outer tube. A collar fitting is mounted to one end of the outer tube wherein the collar fitting is outboard of the sleeve fitting.
