A panel clip formed from a clip pre-form and configured for use with insulated, reinforced duct is provided. The panel clip includes a first plurality of gripping teeth formed in a first panel section. A second plurality of gripping teeth is formed adjacent the first plurality of gripping teeth. A first bending zone is positioned adjacent the second plurality of gripping teeth and opposite the first plurality of gripping teeth. A second bending zone is positioned spaced apart from the first bending zone and opposite the second plurality of gripping teeth. A third bending zone positioned spaced apart from the second bending zone and opposite the first bending zone. A distance formed from the first bending zone to the second bending zone is defined by a thickness of a layer of rigid insulation.

The present invention provides an ultra-long thermally insulated pipeline, which includes a working steel pipe and an outer sleeve steel pipe sleeving the working steel pipe, where an annular vacuum cavity is formed between the working steel pipe and the outer sleeve steel pipe; two ends of the outer sleeve steel pipe are tightened; and the tightened parts of the outer sleeve steel pipe are sealed with an outer wall of the working steel pipe through a plurality of sealing rings. The ultra-long thermally insulated pipeline further includes a spiral ring supporting frame which is disposed outside the working steel pipe and is in contact with a wall of the working steel pipe. The spiral ring supporting frame is made of a phase change material The present invention further provides a forming method of an ultra-long thermally insulated pipeline.

The present invention relates to a pipe for transporting gas, notably carbon dioxide, comprising at least one tubular element, tubular element (1) consisting of a juxtaposition of concentric layers comprising, from inside to outside, at least one sealing layer (5), a wall including a prestressed concrete layer (6) and at least one circumferential mechanical reinforcement layer (8). Furthermore, the concrete making up prestressed concrete layer (6) is selected from among the ultra-high performance fibre-reinforced concretes (UHPFRC).

There is provided a flow pipe including: a pipe body including a side wall having an opening portion; and a heat insulator arranged at an inner peripheral side of the pipe body and having a flow path through which a fluid flows. The heat insulator has an outer peripheral surface facing with the side wall, and the outer peripheral surface has a flow path structure configured to form a flow path that guides a water droplet generated between the heat insulator and the pipe body to the opening portion.

The present invention discloses a superconducting bulk cooling apparatus and cooling method for a high-temperature superconducting magnetic levitation vehicle. The superconducting bulk cooling apparatus for the high-temperature superconducting magnetic levitation vehicle includes a refrigerating machine, a vacuum box and a Dewar tank. A condensing tank is arranged in the vacuum box, and the condensing tank is communicated with the Dewar tank through a nitrogen siphon pipe and a liquid nitrogen return pipe; a heat exchanger connected with the refrigerating machine is arranged in the condensing tank; and a flexible isolation pipe for thermally insulating and isolating the nitrogen siphon pipe and the liquid nitrogen return pipe is connected between the vacuum box and the Dewar tank. The present invention pumps the phase-change nitrogen out of the Dewar tank through a siphoning effect, so that the immersion cooling of high-temperature superconducting bulks is separated from the re-condensation of the nitrogen.

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.
