The invention relates to a method for maintaining the temperature of fluid media in pipes even in the event of an interruption of the fluid media flow. In a first step, a heat reservoir layer (1) is produced comprising a latent heat reservoir material (2) and a matrix material (3). In a second step, the heat reservoir layer (1) is either arranged around a pipe (4) and subsequently encased with a heat damping material (5) or the heat reservoir layer (1) is brought into contact with heat damping material (5), whereby a heat reservoir damper composite (51) is obtained, and the pipe (4) is then encased with the heat reservoir damper composite (51) such that the heat reservoir layer (1) of the heat reservoir damper composite (51) lies between the pipe (4) and the heat damping material (5) of the heat reservoir damping composite (51).

A system for transporting corrosive or erosive fluids having a conduit or flow equipment with a flow bore, comprising; a flexible pipe, an adapter, an end connector, a clamp connector, insert(s), and a metal spacer. Insert(s) comprise an erosion resistant coating disposed around the internal structure that is a spring or helical structure. The insert(s) is/are disposed inside the flow bore and provide erosion and/or corrosion resistance.

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.

A component of an exhaust system for an internal combustion engine. The component comprises an exhaust system structure having an interior through which exhaust gases flow and an exterior, and a thermal insulating wrap for thermally insulating at least a portion of the exterior of the exhaust system structure. The thermal insulating wrap comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder wrap. The pliable binder wrap is wound completely around at least a portion of the exhaust system structure. It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder wrap and the exterior of the exhaust system structure.

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.

A method for producing a fibrous web includes: (a) a fibrous ply containing polylactide fibers and, as necessary, other fibers are laid on a substrate in a random fiber arrangement, (b) initially a loose, pre-compressed nonwoven is created by applying a first pressure to the fibrous ply, the tear resistance of which nonwoven permits free bridging of a span between 0.1 m and 1 m before the nonwoven tears, (c) the pre-compressed nonwoven is then passed through the calender gap, wherein a pattern consisting of point or linear pressure zones is formed in the gap, with the fibers in the pressure zones being exposed to a second pressure, which is higher than the first pressure, and to a temperature such that the fibers fuse.

A prefabricated composite concrete element for use in a corrosive sewer environment. The concrete element has a hollow reinforced cast concrete portion with at least one end having connection details, a premolded corrosion resistant inner plastic liner. The plastic liner lines an interior of the hollow concrete element and the connection details to provide abutting liner faces in an assembled joint to limit exposure through said joint of said concrete portion to corrosive materials arising in said sewer environment. At least two prefabricated composite concrete elements may be assembled end to end at a joint to form a concrete sewer system. Also disclosed are a method of prefabricating such a composite concrete element.

A multi-walled tube that is useful as an analytical column in which chemical mixtures can be separated into their individual components is described. In order to be acceptable as an analytical column, the inner surface of the multi-walled tube must support effective separation, but not react chemically with or contaminate the solvent or the analyte (sample to be separated). Grade 316 stainless steel is typically preferred for this purpose. Moreover, the inner diameter (ID) surface of the multi-walled column is preferably very smooth (less than 10 micro inch Ra) with no interruptions in the surface such as scratches, pits, or asperities. However, since the column is designed to be attached to chromatographic equipment using standard size connection features, the size of standard fittings define the outer diameter (OD) of the column.
