A cylindrical cavity for receiving the tubular article and a metal casing body delimiting a seat substantially inside which the insert is wrapped around the article, the insert having an external projection which extends radially towards the exterior of the insert and is configured to cooperate with a corresponding orifice formed in the seat of the metal body so as to position the insert inside the body, the projection comprising a base attached to the insert and a head provided at the periphery of the head with a protruding clipping edge configured to hold the insert inside the metal casing body. The insert has, at the base of the projection, a through hole extending in line with the clipping edge.

Methods and systems are provided for a flexible support for a vehicle. In one example, the flexible support is formed of a composite material and configured to surround a vehicle component and absorb oscillations generated by the vehicle. The composite material may be a mixture of aluminum particles dispersed in an elastomer matrix.

An assembly, a system, and a method for protecting a portion of a pipeline from an impact in an excavation operation creating a void around the portion of the pipeline with a shell assembly are described. The shell assembly includes two half cylinders and fasteners to couple the two half cylinders together. Each half cylinder has a pipe cover shell, an inner shell, and an outer shell. The pipe cover shell is sized to conform to an outer surface of the pipeline. The inner shell is spaced apart from the pipe cover shell and coupled to the pipe cover shell by radially extended inner supports. Each inner support has a crumple component that is weaker than adjacent portions of the inner support. The outer shell is spaced apart from the inner shell with the inner shell disposed between the outer shell and the pipe cover shell.

A vibration-isolating insert for a pipe clip is adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately, in use, to be positioned between the outer circumference of a pipe and the pipe clip body. The vibration-isolating insert includes an elongate strip of vibration-isolating material which has a pipe facing side and a pipe clip facing side. The strip of vibration-isolating material has adjacent either lateral edge thereof a series of discrete exposed hooks of plastics material which is more rigid than the vibration-isolating material. The hooks protrude relative to the pipe clip facing side of the strip of vibration-isolating material.

A fluid flow conduit assembly includes a flexible conduit having a closed cross section, and a connector. The connector has first and second layers with the flexible conduit extending between the first and second layers, and wherein the first and second layers are permanently attached to each other outside of the flexible conduit.

Described herein are noise attenuating ducts and vehicles using these ducts for environmental control systems. A duct comprises an exoskeleton structure and a sound-absorbing structure, disposed within and conforming to the exoskeleton structure. The exoskeleton structure provides external mechanical support to the sound-absorbing structure thereby helping to maintain the tubular shape of the sound-absorbing structure. This external support does not interfere with the airflow inside the sound-absorbing structure. Furthermore, the external positioning of the exoskeleton structure allows the integration of various support mounting features for the installation of the duct in a vehicle. In some examples, the exoskeleton structure comprises a plurality of enclosed openings to reduce the weight of the exoskeleton structure and provide additional flexibility. Furthermore, additive manufacturing of the exoskeleton structure allows achieving a monolithic structure with various features and characteristics described above.

A pipe hanging system for aligned installation of a pipe from a support system without the use of external measuring devices incudes a hanger assembly having one or more hanger members each having a cradle dimensioned to receive at least a portion of the pipe in a supported relation therein. The hanger members include a plurality of alignment marks disposed on and visible along at least a portion of the hanger member to facilitate positioning the hanger member relative to the support members without the use of external measuring devices. A mounting assembly to mount each hanger member to one of the plurality of support members in an aligned orientation, wherein an aligned orientation is at least partially defined by a portion of the cradle disposed a predetermined distance from a preselected portion of the support member onto which the hanger member is mounted.
