A second layer of physical protection against failure for a fuel line of a vehicle for use with high pressure and cryogenic fuels increases safety. The primary fuel line can be assembled from one or more components. The secondary protection is a single outer sleeve that includes a selectively permeable or impermeable membrane and may be reinforced. The sleeve and enclosed volume can also be used to protect against oxygen liquification in cryogenic applications. A means to detect failure of the primary fuel line and optional means to vent leaking fuel depend on the application. Clamp designs may be used to mount and clamp such assemblies in a vehicle structure.

Hemp fibers may be disposed throughout or in selected portions of a hose (e.g., an expandable water hose). The hemp fibers deployed in the hose enhance the durability of the hose, and imparts various advantageous properties (e.g., anti-microbial or anti-bacterial, mildew-resistant, odor reduction, moisture wicking, etc.) to the hose.

The invention relates to a retractable pipe whose wall is formed of at least one flexible gas-impermeable and/or liquid-impermeable tape welded by its selvages in the form of a cylindrical helix and of at least one metal wire in the form of a cylindrical helix whose pitch is the same as the one formed by said band, characterized in that said tape is a double fabric textile comprising at least two regions where the two fabrics work together to delimit at least one inflatable zone, said textile being covered with a coating layer of a gas and/or liquid-impermeable material.

A heat resistant hose is described. The hose may include a first outer protective and structural woven reinforcing layer comprising a first tubular fabric structure, a second inner protective and structural woven reinforcing layer comprising a second tubular fabric structure, where the second inner protective and structural woven reinforcing layer is within the first outer protective and structural woven reinforcing layer, a hose innermost extruded waterproofing layer comprising an elastomeric material, the hose layer being bonded to, adhered to, or impregnated into or through the second protective layer, the innermost extruded waterproofing layer is within the inner protective and structural woven reinforcing layer, and an intermediate layer interposed between the first outer protective and structural woven reinforcing layer and the second inner protective and structural woven reinforcing layer, the intermediate layer comprising a fabric laminated with a reflective material.

Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.
