The fibers of the strands of the plurality of strands of fibers are mineral fibers, and the plurality of strands of fibers is embedded in the layer of polymer material.

One aspect of the invention provides an energy-dissipative fuel gas tube including: a length of corrugated stainless steel tubing; an inner resin layer surrounding a radially outer surface of the corrugated stainless steel tubing; a laminated foil layer surrounding a radially outer surface of the inner resin layer; and an outer resin layer extruded over a radially outer surface of the laminated foil. The laminated foil layer includes: a foil and a high-tensile-strength material bonded to the foil. Another aspect of the invention provides an energy-dissipative fuel gas tube including: a length of corrugated stainless steel tubing; a resin layer surrounding a radially outer surface of the corrugated stainless steel tubing; and a laminated foil layer surrounding and bound directly to a radially outer surface of the resin layer. The laminated foil layer includes: a foil and an outer protective layer bonded to the foil.

Provided is a hydrogen-dispensing hose. At least two reinforcing layers are coaxially layered between an inner surface layer of a thermoplastic resin having a dry hydrogen gas permeability coefficient at 90 C. of 110.sup.8 cc.Math.cm/cm.sup.2.Math.sec..Math.cmHg or less and an outer surface layer of a thermoplastic resin. A wire braided layer formed by braiding metal wires is used as the outermost reinforcing layer. Fiber braided layers formed by braiding high-strength fibers such as polyparaphenylene benzobisoxazole fibers are used as the other reinforcing layers.

A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.

The extensible hose (1) comprises a first elastically extensible tubular element (2) and a second tubular element (3) extendable and coaxial to said first tubular element (2). The second extendable tubular element (3) is inserted into said first elastically extensible tubular element (2). Herein proposed is also an extensible hose unit (G) comprising the hose (1) and at least one fitting (11) associable to at least one end of the hose (1), for connecting to liquid dispensing structure and/or a user device.

A stop ball for a tube for fluid or energy is provided. The stop ball comprises a singular hollow body. The hollow body comprises and is integral with a first opening for the tube and an attachment means for attaching the stop ball to the tube, the attachment means comprising a second opening for the tube. A method for attaching a stop ball according to any one of the preceding embodiments to a tube for fluid or energy is provided. The method comprising inserting the tube through all three openings; pulling the attachment means at least partly out of the hollow body; and clamping the attachment means onto the tube.

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.

In a process for the manufacture of an impermeable connection between at least two fluid carrying silicone hose components, the silicone hose components and a silicone connector component are first prepared. Afterwards a fluid silicone mass is applied to at least one connecting area where the silicone hose components abut on the silicone connector components. The at least one connecting area is post cured to harden the silicone mass. In a fluid carrying assembly with at least two fluid carrying silicone hose components and at least one silicone connector component, a fluid carrying connection is manufactured between these components by means of this process. This design results in a connecting technique that is, on the one hand, secure and, on the other hand, enables automation of the manufacture of an impermeable connection and thus of the fluid carrying assembly.
