A system for transporting corrosive or erosive fluids having a flow conduit or flow equipment with a flow bore. One or more inserts (50) are disposed within the flow bore of the flow conduit or flow equipment. The insert(s) (50) include an internal structure (52) and an erosion or corrosion resistant coating (54) disposed around the internal structure. The insert(s) (50) is/are disposed inside the flow bore and provide erosion and/or corrosion resistance.

A system and method of detecting a disturbance of a buried structure, for example an intrusion or a leak from a pipeline. Sensing devices at discrete locations connect with a backbone cable extending along a length of the pipeline. In the event of a leak, the signal from a sensing device is received at an output, via the backbone cable, providing notification of the leak and the location of the leak.

A coded cartridge holder for use with a drug delivery device is provided. The cartridge holder includes a fastener that becomes operative based in part on a length of a cartridge or a diameter of the cartridge. In one embodiment, the cartridge holder is coupled to the drug delivery device. The cartridge holder comprises a first blocking feature. The drug delivery device includes a cartridge detector comprising a second blocking feature. This feature may be a pin, for engagement with the first blocking feature of the cartridge holder when the cartridge acts on the cartridge detector. The cartridge holder may further include a fastening mechanism configured to fasten the cartridge holder to the drug delivery device only when the second blocking feature engages the first blocking feature.

Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.

The present invention relates to a marine drilling riser joint, adapted for the securement of one or more umbilicals (36) thereto. The marine drilling riser joint comprises one or more umbilical gutter assemblies (8), connected to or formed integral in an outer surface of a buoyancy module on the exterior of the marine drilling riser joint and provided parallel to the riser pipe, the umbilical gutter assembly comprising: an umbilical gutter (8) adapted to accommodate one or more umbilicals; and a resilient gutter cover (82a, 82b), which is elastically deformable by a loom tool, which resilient gutter cover in a closed position covers the umbilical gutter and in an elastically deformed position provides a working clearance to allow the one or more umbilicals to be introduced into the umbilical gutter.

A modular kinematic and telemetry system for an irrigation system includes a condition-based monitoring (CBM) system and a plurality of sets of modular foot assemblies. The CBM system has a housing and supports a plurality of kinematic and telemetry components. The plurality of sets of modular foot assemblies includes a first set and a second set that secure to the housing of the CBM system. The first set is configured to secure the CBM system to a first end gun configuration and the second set is configured to secure the CBM system to a second end gun configuration that is different from the first end gun configuration.
