Techniques for implementing and operating a system that includes a pipe segment, which has tubing that defines a bore and a fluid conduit implemented in an annulus of the tubing, and a test head. The test head includes a shell, which defines an annulus cavity, and an inflatable bladder implemented in the annulus cavity, in which the system maintains the inflatable securing bladder in a less inflated state while pipe segment tubing is not present in the annulus cavity and increases inflation of the inflatable bladder to a more inflated state when the tubing is present in the annulus cavity to facilitate securing and sealing an open end of the pipe segment in the test head to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the annulus of the tubing via a testing port on the shell.

The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.

A weight assembly is fixed on a hose of a faucet and contains: a tubular retainer and a counterweight. The tubular retainer includes a first segment, a second segment, a fitting orifice, an opening, an engagement portion, and a forced portion. The counterweight includes a third segment, a fourth segment, a through orifice, and a press portion. After the tubular retainer is fitted on the hose, the fourth segment of the counterweight moves toward the first segment of the tubular retainer so that the press portion presses the forced portion of the tubular retainer after the tubular retainer is accommodated into the through orifice, and the forced portion retracts inward to actuate the engagement portion to engage with the hose.

An inspection crawler, and systems and methods for inspecting underwater pipelines are provided. The system includes the inspection crawler having a housing with a first side, an opposing second side, a power source, and a controller. The crawler includes an inspection tool, at least two pairs of latching arms, each latching arm including a rolling element, and at least two pairs of driving wheels. The system also includes at least one communication unit configured to communicate with the inspection crawler and to communicate aerially with one or more remote devices and, and at one sea surface unit. The inspection crawler can further include a connecting structure connecting the front and back portions of the crawler, and configured to elongate and shorten the inspection crawler.

A hose restraint system includes a base, a key, and a flexible connector. The flexible connector is secured at a proximal end to the key and at a distal end to a flexible hose. The key is configured to releasably engage the base. The base includes a sensor that provides a control signal to a control system indicating whether the key is in the locked position. The control system provides an operational interlock to prevent fluid flow in the flexible hose if the key is not in the locked position.

A system for underwater inspection including an inspection crawler are provided. The inspection crawler includes a housing having first and second sides, a power source, a controller, an inspection tool, at least two driving wheels, and a moveable center of gravity. A method for traversing a weld joint with the inspection crawler having a moving mass is also provided. In the method, the crawler is parked proximate to the joint, and the mass is slid along a slide rail to the second end of the crawler distal to the joint. The first end of the crawler is then propelled over the joint and the mass is slid to the center of the crawler. A center portion of the crawler is then propelled over the joint and the mass is slid to the first end of the crawler. The second end of the crawler is then propelled over the joint.

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 extraction device for a heating tracer includes a clamping assembly and a driving member. The clamping assembly includes a connecting seat, a first extrusion wheel and a second extrusion wheel rotatably arranged on the connecting seat. The first extrusion wheel and the second extrusion wheel are both an eccentric wheel. In use, the heating tracer is clamped between the first extrusion wheel and the second extrusion wheel, and is in contact with an outer circumference of the first extrusion wheel and the second extrusion wheel. The driving member includes a main body and a drive shaft arranged thereon. The main body is configured to drive the drive shaft to extend along an axial direction of the main body. The drive shaft is connected to an end of the connecting seat away from the first extrusion wheel and the second extrusion wheel.
