A connector assembly for connecting a corrugated tube with a braid mounted on the periphery of the hose to a metal connector, comprises an inner sleeve mounted on the corrugated tube, and an outer sleeve mounted on the inner sleeve, the inner and outer sleeve cooperating with each other to hold the braid between the inner and outer sleeves. The inner and outer sleeves have respective inner and outer tapered surfaces. One of the inner and outer tapered surfaces has one or more portions projecting toward the other of the inner and outer tapered surfaces.

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.

Described herein are fire hoses incorporating new combinations of materials to increase the hose's resilience. Resilient hoses include those made with silicone-coated fabrics or with thermally-resistant fabrics or both.

Disclosed is a water pipe with synchronously retractable multi-layer, comprising: a retractable inner pipe; a fabric sleeve sleeved outside the inner pipe, which is configured as a retractable cylindrical or corrugated one- or multi-layer fabric sleeve formed by interweaving retractable elastic yarns arranged at intervals in the axial direction and non-retractable reinforcing yarns arranged at intervals in the circumferential direction; and a retractable plastic film layer interposed between the inner pipe and the fabric sleeve. According to the present disclosure, the inner pipe, the plastic film layer and the fabric sleeve can be synchronously retracted under the effect of water pressure change, so that the frictional damage among multiple layers is effectively reduced, and the service life of the entire retractable water pipe is prolonged.

Systems and methods are provided for consolidating a preform of braided fiber. One embodiment is a method that includes acquiring a braided preform comprising fibers of unidirectional material that have been woven into a shape having a closed cross-section, disposing the braided preform within a mandrel, disposing an inflatable bladder within the closed cross-section of the braided preform, and iteratively applying pressure to the braided preform via the bladder to consolidate the braided preform against the mandrel.

Examples of fiber reinforced and powered coil tubing include a hollow fiber reinforced composite coiled tubing with a tubing wall having an inner surface, an outer surface and a wall thickness. The inner surface is formed to prevent absorption of fluids flowed through the coiled tubing to the tubing wall. The tubing can connect a power source at a surface of a wellbore to downhole equipment positioned within the wellbore. An electrical power conductor is embedded in the tubing wall. The conductor can transfer power from the power source to the downhole equipment. The tubing can be used to lower, install and remove downhole equipment into the wellbore without a work-over rig. The downhole equipment can be operated by transmitted power through the electrical power conductor.
