Abstract: A woven tubular liner comprising an outer surface comprising outer wefts and warps and an inner surface comprising inner wefts and the warps, wherein the inner and outer surfaces are connected by the warps, the outer wefts being protected from an environment inside of the tubular linear and the inner wefts being protected from an environment outside of the tubular liner. The method comprises repeating a weaving unit of continuous outer wefts and continuous inner wefts running uninterrupted along a circumferential direction, woven with continuous warps running along a longitudinal direction, offsetting positions of the warps relative to the wefts in the weaving unit, selectively interlacing outer wefts with the warps, and selectively interlacing inner wefts with the warps.

Abstract: A seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired.

Abstract: A hose with an improved flow includes a method of manufacture of the same. The hose with an improved flow includes an extruded inner tube and a non-woven material layer disposed over the extruded inner tube. The layer of non-woven material is in direct contact with the extruded inner tube and is fused thereto. The hose with an improved flow further includes at least one woven jacket disposed over and fused to the layer of non-woven material. The presence of the layer of non-woven material results in a smoother inner surface of the inner tube, which helps improve the flow of water in the hose, as well as in other favorable characteristics.

Abstract: Methods and systems for a flexible hose assembly are provided. The flexible hose assembly includes a core tube including a substantially fluid-impervious body including an inner surface and an outer surface, and an aramid sleeve including aramid yarn, the aramid sleeve circumferentially covering the core tube.

Abstract: The invention relates to a heat protection device between a first and a second zone. The second zone can be subjected to relatively sudden and large variations of temperature and pressure. The device includes a screen disposed between the two zones. According to the invention, the screen is thermally insulating. At least a part of the screen is constructed of a material which is pressure-permeable and flexible.
