A separation duct for encompassing an elongate member. The duct includes longitudinal internal spacers extend longitudinally in a direction of a longitudinal axis of the duct. A longitudinal plane for each spacer is substantially parallel to the longitudinal plane of the other spacers. The spacers support the elongate member and resist slippage of the duct relative to the elongate member. The duct may be used to provide separation and protection for elongate members of a range of outside dimensions.

A casing spacer which allows for the positioning of a carrier pipe or set of carrier pipes in a desirable location inside a casing pipe.

The present disclosure describes an outer utility pipe having a first diameter. In a first embodiment, the present disclosure describes an inner liner having a second diameter. The second diameter is smaller than the first diameter. The inner liner is positioned inside the outer utility pipe such than an annular space is created between the inner liner and the outer utility pipe. The inner liner is configured to conduct fluid. The present disclosure describes a communication conduit positioned in the annular space between the inner liner and the outer utility pipe. The communication conduit is configured to receive one or more components, such as fiber optic cables, configured to transmit information. In a second embodiment without an inner liner or an annular space, the communication conduit is received by a channel cut in an inner diameter surface of the outer utility pipe.

A pipe-in-pipe assembly with thermally-insulating spacers positioned in an annulus to act radially between inner and outer pipes is disclosed. The spacers have at least one circumferentially-extending array of circumferentially-spaced ribs that define longitudinally-extending passageways in gaps between neighbouring ribs of the array. Cables including heating elements extend longitudinally along, the annulus outside the inner pipe. The cables extend longitudinally along the passageways. At least one insulation layer disposed radially outboard of the cables has insulating elements disposed in the gaps between the ribs and/or an insulating layer extending around the inner pipe, positioned radially outboard of the ribs and bridging the gaps. Bands encircle and retain components of the insulation layer. Insulation may also be disposed on the inner pipe between first and second arrays of ribs, those arrays being spaced longitudinally from each other.

An apparatus that includes a conduit having a first end, a second end, and a longitudinal axis. The conduit may define an inner channel and may be configured to extend through a vane cavity of a vane. The apparatus may further include a damping finger that includes a first portion coupled to the conduit and a second portion diverging outward at an angled orientation from the conduit. The damping finger may be resiliently flexible and the second portion of the damping finger may be configured to contact an inner surface of the vane.
