An aircraft motive flow line includes an outer tube made out of a first material and an inner tube extending longitudinally inside the outer tube. The inner tube is made out of a second material having a thermal conductivity coefficient lower than that of the first material. The first material has a strength coefficient greater than that of the second material. The inner tube is sized and held in position relative to the outer tube so as to define a gap between an exterior of the inner tube and an interior of the outer tube. A port fluidly connects an interior of the inner tube to the gap.

A pipe coupon extraction tool includes: a rod defining a first end, a second end, and a central axis; and a spring bar defining a first end and a second end, the spring bar rotatably secured to the rod, a surface of the spring bar configured to be angled with respect to the central axis when the pipe coupon extraction tool is engaged with a pipe coupon.

A pig routing insert or drain is used in various subsea systems having a block structure, e.g., block manifolds, with a plurality of perforated fluid passages. The insert generally includes a substantially unrestricted flow opening configured to allow substantially unrestricted fluid flow and passage of a cleaning pig, and a partially restricted opening having at least one pig blocking structure, in which the partially restricted opening is configured to allow substantially unrestricted fluid flow through the partially restricted opening whilst blocking the passage of the cleaning pig through the partially restricted opening. A method for manufacturing and installing the pig routing insert or drain in a machined block manifold includes positioning a manufactured pig routing insert at an intersection of first and second perforated fluid flow holes formed in a body of a structure and fastening the manufactured pig routing insert within the intersection in the body.

A fracturing fluid delivery system with a fluid conduit having a communication line is provided. In one embodiment, a fracturing system includes a wellhead assembly and a fracturing fluid conduit coupled to the wellhead assembly to enable receipt of fracturing fluid by the wellhead assembly from the fracturing fluid conduit. The fracturing fluid conduit includes a body defining a bore for conveying the fracturing fluid to the wellhead assembly and also includes a communication line. The communication line transmits signals along the body of the fracturing fluid conduit such that the fracturing fluid conduit facilitates transmission of both the fracturing fluid and the signals. Additional systems, devices, and methods are also disclosed.

A sewage line plug assembly is disclosed herein. The assembly comprises a plug housing having a hollow configuration. Additionally, a diaphragm plate is disposed within the plug housing including a first element disposed on the first operative end of the diaphragm plate. Furthermore, first element is configured to depress due to pressure acting thereon due to sewage build up inside a sewage line. The housing further includes a second element disposed on the inner bottom end of the housing. Additionally, the second element interacts with the first element and is configured to depress due to depression of first element. Sewage line plug assembly further includes an alarm unit coupled to second element and configured to sound an alarm on depression of second element. The alarm sound of the alarm unit is configured to sound when the pressure exceeds a pre-determined threshold value.

A pipe splitting assembly includes an articulating hammer nose assembly having a pipe splitting cutter and a rotatable joint coupled with the pipe splitting cutter. A pneumatic hammer is distal to the articulating hammer nose assembly, The pneumatic hammer is configured to drive the articulating hammer nose assembly proximally away from the pneumatic hammer. The rotatable joint is coupled between the pipe splitting cutter and the pneumatic hammer, and the articulating hammer nose assembly is rotatable into one or more angles relative to the pneumatic hammer through the rotatable joint. A cable coupling is interposed between the pneumatic hammer and the articulated hammer nose assembly. The cable coupling is configured to attach a cable to the pipe splitting assembly. The cable coupling and the rotatable joint are configured to transmit to the pipe splitting cutter a compression force from the cable coupling and dynamic percussive forces from the pneumatic hammer.

The present invention relates to a hose line (1) for transporting abrasive media with an electrically conductive reinforcing element (5) running in or on the hose wall (2) and extending in the hose direction (6), wherein an insert (7) made of electrically conducting material is at least partially embedded in the hose wall (2) and extends in the hose direction (6) at a distance from the reinforcing element (5).
