Abstract: Push-on hose construction for a self-gripping connection with a barbed nipple or other push in fitting end. The hose has an innermost core tube which exhibits a reduced coefficient of friction for easier insertion of the fitting end. Such core tube may be extruded or otherwise formed of thermoplastic polyurethane or other resin which is dulled or otherwise incompatibilized by the addition of an immiscible such as nonpolar polyolefin homopolymer, copolymer, or mixture thereof.

Abstract: Flexible thermoplastic hose bundle for use in the operation and control of Blow-Out Prevention (BOP) valves and other devices located on subsea well heads. The bundle includes a plurality ?-inch inner diameter (ID) hoses which are cabled around a central hose and sheathed in an outer jacket.

Abstract: A hose (1) comprising a core tube (2), a reinforcement layer (3) surrounding the core tube (4), and a cover (4) surrounding the reinforcement layer, wherein at least one of the core tube (2) and cover (4) are made of a thermoplastic material comprising one or more thermoplastic polyether-polyester block copolymers, and said thermoplastic material has a Shore D hardness no less than about 60.

Abstract: A process for assembling a rigid fitting to a flexible or elastic tube or hose within one of a portable, hand-held and/or mountable assembly device, including the steps of slip-fitting the fitting within a pusher member of the device that includes a torque-producing source capable Of converting input power into linear motion force; b. temporarily restraining a hose open end within the assembly device and; activating the torque-producing source to linearly advance the pusher member and fitting, relative to the restrained hose end, for physically inserting the fitting into the hose open end. Additional steps include: retraction of the pusher member and releasing the now-assemble hose and fitting assembly from the assembly device. Product-by-process claims and article claims, pertaining to the assembly device used in the process for assembling, are also set forth.

Abstract: A flexible hose adapted construction for conveying fluids under pressure. The construction includes a core tube having a circumferential inner core tube surface and an opposing circumferential outer core tube surface. A first reinforcement layer surrounds the outer core tube surface, and is formed of one or more filaments of a first fiber. A second fiber reinforcement layer surrounds the first reinforcement layer, and is formed of one or more filaments of a second fiber. The first and second reinforcement layers are bonded together by means of a bonding agent such as an adhesive, resin, plasticizer, tackifier, or solvent, the application of which is controlled to wet only a portion of the filaments of the reinforcement layers.

Abstract: Multi-layer tubular polymeric composite and to articles such as tubing and hoses constructed thereof. The composite is formed of a layer of a fluoropolymer material bonded directly to a second layer of a more general purpose resin material which may be a nylon or other polyamide.

Abstract: A flexible hose construction adapted for conveying fluids under pressures and capable of withstanding relatively high external pressures without collapsing. The tubular construction includes a first reinforcement layer, an inner jacket surrounding the first reinforcement layer, a second reinforcement layer surrounding the inner jacket, and outer jacket covering the second reinforcement layer.

Abstract: A flexible hose construction adapted for conveying fluids under relatively high internal pressures and capable of withstanding relatively high external pressures without collapsing. The construction includes a tubular first elastomeric layer having a first inner radial surface and a first outer radial surface, and a tubular second elastomeric layer having a second inner radial surface and a second outer radial surface. A helical reinforcement element is spiral wound over the first elastomeric layer as interposed between that layer and the second elastomeric layer. The element is wound at a predetermined pitch angle to define a series of turns each being spaced-apart from an adjacent turn to define an interstitial area therebetween.
