Abstract: An electrically conductive hose cutting clip has at least one end tab that is shaped to provide a cutting edge for penetration of the inner layer(s) of a multiple layer fluid conveyance hose when it is clipped onto a fluid connector and the hose is installed on the fluid connector by forcing it onto the connector. The cutting action by the cutting clip provides for a relatively low resistance electrical connection between an electrically conductive layer of the hose and the fluid connector. This can be used to provide a signal path from a sensing element on or in the hose to a system electronic component.

Abstract: An apparatus is provided for joining and sealing conduits, includes edge trim, a sleeve, and a retaining element. The edge trim is shaped to mount upon and engage an end of a conduit. The sleeve extends between the conduits and at least partially surrounds the edge trim. The sleeve may be made of compressible material, such that when the retaining element surrounds a portion of the sleeve and the edge trim, the retaining element generally compresses the portion of the sleeve portion underlying the retaining element and displaces the sleeve material to expand on either side of the retaining element and limit movement of the retaining element. The method of joining and sealing conduits includes mounting the edge trim and a retaining element upon an end of a conduit, extending a sleeve between the conduits, and sliding the retaining element over the sleeve toward the end of the conduit.

Abstract: In a method of securing tensile reinforcement elements (7) of a pipeline or a cable to an end termination (18), the end termination is provided with a plurality of locking holes through which the reinforcement elements to be secured are pulled. Insertion of a spreader element into the reinforcement element results in a local cross-sectional increase in the tensile reinforcement. The reinforcement element cannot move freely through the locking hole because of the local cross-sectional increase, thereby achieving mechanical locking.

Abstract: An end fitting in which to receive a flexible pipe end to be joined includes an annular seal unit comprised of a resilient elastomeric composition contained in a tapered rigid housing ring force fit in a tapered recess of a surrounding component so as to engage the outer surface of the received pipe end.

Abstract: A diffusion-tight fluid conduit for hydrocarbon-containing fluids has a corrugated pipe of corrosion-resistant metal with a corrugated inner side and a corrugated outer side, wherein the outer side is exposed. An inner pipe of plastic material is arranged inside the corrugated pipe and has a smooth inner side and a smooth outer side. A first coupling member is seal-tightly connected by material bonding to a first end of the corrugated pipe.

Abstract: An assembly of an end-fitting and a flexible pressure pipe which is of a non-bonded structure and comprises a number of layers including at least one layer (5) having a number of helically wound flat metallic tensile armour wires with end parts which, in the assembled condition, are embedded in an anchor consisting of a casting material such as epoxy which is injected into a cavity formed in the end-fitting. The flat wire end parts have at least one twist turning generally around the centerline of the wire. Said twists lock the tensile armor wires firmly in the anchor and therefore provide a greater resistance to axial tensile loads acting on the assembly than has been known before. Furthermore the joint is a simple and cheap structure and can be made in situ.

Abstract: A method for forming a fitting at an end of a braid-reinforced silicone tube. A short length of the outer layer surrounding the braiding is removed and the exposed braiding is folded back over a first silicone ring and then a second silicone ring is placed over the folded-over braiding. The end of the tube is then placed in a mold which is then filled with liquid silicone. After the silicone is heated and cured, a unitary structure of tube and fitting results. Since the braiding is part of the unitary structure, it cannot be pulled out, thereby increasing the reliability of tube and fitting.

Abstract: A method is disclosed for coupling a stub end flanged connector to a fiber reinforced plastic pipe. The method includes tapering an end of the fiber reinforced plastic pipe on the outside surface of its fiber overwrap. An inside surface of a stub end connector is correspondingly tapered. The stub end connector is then bonded to the fiber reinforced plastic pipe. A liner of the plastic pipe is then flared to correspond to a flared end of the stub end connector. Then at least one stiffness transition layer is bonded over the plastic pipe and the stub end connection, over an axial span at least including a termination of the taper in the stub end connector.

Abstract: Tubular structures are described which are composed of multiple layers of reinforced material. The structures include at least one terminal end portion which includes one or more wedges between adjacent layers of reinforced material. The structures may be, for example, hoses, expansion joints, or actuators (e.g., air springs). The terminal end portions can be readily clamped together to make appropriate connections, or a terminal end portion can be clamped to a desired mounting surface.
