A piping is provided with an RFID tag for identifying the piping, wherein the piping comprises a first end section for being coupled to a second piping and a second end section for being coupled to a third piping. The piping further comprises a mid-section in between the end sections. The RFID tag is provided in an elongate recess that is formed in the piping and that extends in a tangential direction parallel to a surface of the mid-section of the piping.

One aspect provides a method, including: storing an infrastructure project summary report with one or more other infrastructure project reports pooled in a database of project summary reports; the infrastructure project report being prepared via accessing fluid conveyance infrastructure summary data describing a condition of a fluid conveyance infrastructure segment; and using a processor of an electronic device to match the infrastructure project summary report with one or more other infrastructure project reports pooled in the database of project summary reports. Other aspects are described and claimed.

A safety device with a sliding cable and a corresponding installation, to secure conduits, pipes, piping and similar equipments subject to high pressure due to fluid under pressure circulating in such conduits and equipments. The safety device includes a flexible cable which forms a first and a second attachment eyelet for attaching and connecting the safety device to two parts of the conduits and equipments under pressure. A first and a second sleeve which close two end portions of the flexible cable form, at the ends of the safety device, the first and second attachment eyelets. Two terminals are provided at the opposite ends of the flexible cable.

A wire housing protector in which a locking mechanism includes an elastic projecting piece provided in a lid with an engagement protrusion on an outer surface of its leading end, and an elastic projecting piece insertion portion that is provided in a side wall of the protector body, and includes an engagement portion that engages with the engagement protrusion, contact surfaces include first engagement surfaces that each extend from the side wall side of the protector body toward a side to which the engagement protrusion protrudes, second engagement surfaces that extend from end portions of the first engagement surfaces toward the lid side, and third engagement surfaces that extend from end portions of the second engagement surfaces toward the side to which the engagement protrusion protrudes.

A two-part, selectively dockable robotic system having counterbalanced stabilization during performance of an operation on an underwater target structure is provided. The robotic system includes a first underwater robotic vehicle that is sized and shaped to at least partially surround the underwater target structure. A second underwater robotic vehicle is sized and shaped to at least partially surround the underwater target structure and selectively dock with the first underwater robotic vehicle. The first and second robotic vehicles include complimentary docking mechanisms that permit the vehicles to selectively couple to each other with the underwater target structure disposed at least partially therebetween. One robot includes a tool that can act upon the target structure and the other robot includes a stabilization module that can act upon the target structure in an opposite manner in order to counterbalance the force of the tool.

Pipeline segments can contain cables, such as communication cables (e.g., fiber optic cables) within insulation material surrounding the pipeline segments. Cables can be embedded within the insulation material, run through conduits embedded within the insulation material, placed in channels formed in the insulation material, or otherwise. Channels containing one or more cables can be filled with supplemental insulation material, thus securing the cables within the channels. Pipelines created as disclosed herein can enable data transfer between distant points without the need to lay fiber optic cable in addition to the pipeline. Further, fiber optic cable embedded thusly can be used to sense conditions in the pipeline, such as leaks, seismic activity, strain, and temperature information.

An elastic projecting piece insertion hole is defined by an outer wall portion, an inner wall portion that opposes the outer wall portion across a gap, and a left wall portion and a right wall portion that connect edge portions on both sides of the outer wall portion and the inner wall portion. A first tapered surface whose height gradually decreases from an outer edge toward an inner edge is formed at an upper surface of the outer wall portion. An upper surface of the inner wall portion is set to be lower in height than the outer edge of the upper surface of the outer wall portion. Second tapered surfaces whose height gradually decreases from the height of the outer edge of the upper surface of the outer wall portion toward the height of the upper surface of the inner wall portion are respectively formed at upper surfaces of the left wall portion and the right wall portion.

A pipe for a driven-type fluid machine includes: an inlet pipe that is to be connected to a suction port provided in a casing of the driven-type fluid machine, a supply pipe that supplies a fluid, and a bend that connects the supply pipe and the inlet pipe to each other. The bend is shaped such that a pipe width in a plane including a pipe axis of the inlet pipe and a pipe axis of the supply pipe gradually decreases from an upstream portion to a bent portion, and L13d is satisfied where d is the pipe width at the bent portion and L1 is an axial length of the inlet pipe.

A draining device for draining a fluid line is provided. The draining device comprises a mechanically non-locking coupling and a holding device. The mechanically non-locking coupling is configured to establish a fluid conductive connection with the fluid line. The holding device is configured to stationary fix the mechanically non-locking coupling relatively to the fluid line. The draining device allows establishing a fluid conductive connection between the fluid line and the mechanically non-locking coupling without requiring a mechanical fixation directly at the mechanically non-locking coupling.
