Abstract: A transportation pipe includes a main-body vacuum insulated pipe, a central pipe, and a connecting vacuum insulated pipe. The main-body vacuum insulated pipe including a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. The central pipe through which a fluid to be transported flows, is arranged in the main-body vacuum insulated pipe. The connecting vacuum insulated pipe having a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. In a state in which two main-body vacuum insulated pipes are inserted into the connecting vacuum insulated pipe from respective ends of the connecting vacuum insulated pipe, ends of the main-body vacuum insulated pipes are away from one another, and the main-body vacuum insulated pipes are connected to one another via the connecting vacuum insulated pipe.

Abstract: A tube can include a sidewall defining a lumen profile. The sidewall can include a plurality of alternating thin regions and thick regions. The lumen profile can include a plurality of alternating large radius and small radius regions. The thin regions or large radius regions can include elastic instabilities adapted to form an essentially complete closure of the lumen profile at minimal compression.

Abstract: Device for a double hose structure with an inner main hose and an outer cover hose defining an annular space giving buoyancy in water. At least one end is provided with a coupling member forming a mount for the main hose and the cover hose which at a free end merges into a threaded portion for connecting the hose assembly to an auxiliary connection. The coupling member comprises an inner coupling sleeve connected to one end of the main hose and an outer coupling sleeve connected to the cover hose, the inner and outer coupling sleeves being mutually connected forming a liquid tight termination of the annulus by a ring-shaped plate. The plate is attached with screws through holes only to the outer sleeve, the plate being forced against a shoulder of the inner coupling sleeve by a ring nut with internal threads matching external threads on the inner sleeve.

Abstract: A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.

Abstract: The present invention is an array of sanitary tissue products. The array of sanitary tissue products comprises a first packaged article and a second packaged article. The first packaged article comprises a first rolled sanitary tissue product wound onto a first fibrous core. The second packaged article comprises a second rolled sanitary tissue product wound onto a second fibrous core. The second rolled sanitary tissue product is wound loosely relative to the first rolled sanitary tissue product. The second fibrous core has an axial strength greater than the first fibrous core.

Abstract: The present disclosure is directed to a fibrous core comprising a fluted layer; and a liner disposed on the fluted layer. The fluted layer and the liner are helically wound defining a longitudinal core axis.

Abstract: A protective sleeve for being installed around a longitudinal portion of a pipe (72) for transporting hydrocarbons. The sleeve includes a set of rings, each of which has two opposite flanks (16, 18), and which are retained together in series, with the flanks (16, 18) opposite each other, by a plurality of elastically deformable connecting elements (32). The bending of the longitudinal portion is capable of causing contraction of the connecting elements (32) located towards the inside of the curve, as well as the elongation of the opposite connection elements (32), in order to resist the bending. Each connecting element (32) has two opposite rigid attachment portions (34, 36) and an elastic deformable body (38) interposed between the two attachment portions. The attachment portions (34, 36) are attached to the flanks (16, 18) opposite the rings (10), respectively.

Abstract: Liners useful as piping elbow liners comprising a body liner, a tangential inlet liner, and a tangential outlet liner. The tangential inlet liner and the tangential outlet liner can be removably inserted into a cavity in the body liner. The body liner can comprise two substantially-identical body section liners.

Abstract: A multiple-layered, translatedly rib-stiffened, composite hollow cylinder d method for fabrication thereof utilizing filament winding techniques known in the art. An inner skin is wound over a mandrel; then, circumferential ribs are wound over the inner skin, pin rings are placed at the axial ends of the mandrel, longitudinal stringers are engaged with the pin rings and wound over the circumferential ribs, circumferential bands are wound near the axial ends over the longitudinal stringers, and another skin is wound over the circumferential bands and longitudinal stringers; these steps, commencing with the winding of circumferential ribs and concluding with the winding of an additional skin, are repeated as many times as desired, each repetition forming an additional layer, with the circumferential ribs for each additional layer being longitudinally staggered in relation to the circumferential ribs for the previous layer.

Abstract: A flexible pipe comprising a first set of stress bearing elements extending substantially the whole length of the pipe, for accommodating maximum hoop stress resulting from flow of pressurized fluid through the pipe, and a second set of stress bearing elements extending substantially the whole length of the pipe for accommodating longitudinal stress resulting from a flow of pressurized fluid through the pipe.

Abstract: An anti-holiday cable armor for submersible electrical cables comprising two generally helically wrapped, overlapping metal straps, the second metal strap being wrapped longitudinally in a direction opposite to the direction of wrap on the first metal strap, for providing anti-holiday protection when the cable is pulled in either direction is disclosed.
