    Abstract: Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.

  • Publication number: 20140034180
    Abstract: A pipe attachment assembly for attaching a pipe to another structure so stresses are reduced within the assembly includes a sleeve positioned outside the pipe which is composed of a material stronger than the pipe material, and an elastomeric bonding material which fills a gap between the pipe and the sleeve. The elastomeric bonding material transfers forces which are externally imposed on the pipe to the sleeve. This reduces bending, compression, tension, or torsion of the pipe in response to external forces, which in turn reduces the risk of a pipe failure at or near the termination or a breach where the pipe forms a joint with other pipes or containers. Various configurations may further improve the transfer of shearing stresses from the pipe to the sleeve, for example varying the width and/or the shear modulus of the elastomeric bonding material along the length of the pipe.

The method includes wrapping a corrosion-resistant, inner wrap around first and second pipes such that this wrap surrounds the joint region and adheres to the pipes. A fiberglass-composite outer wrap is wrapped around the inner wrap and the first and second pipes such that the outer wrap surrounds the inner wrap and adheres to the pipes. The outer wrap is cured.

  • Publication number: 20130112310
    Abstract: An assembly and a method for reinforcing or repairing one or more segments of an existing pipeline, without taking the pipeline out of service and without the need for disassembling the existing pipeline segments that are to be repaired. The assembly incorporates a metallic reinforcement pipe, a front seal ring, a rear seal ring, a front seal ring retention assembly, a rear seal ring retention assembly, and a self-hardening medium receiver. The reinforcement pipe and the seal rings create an annular space between the respective ends of the reinforcement pipe and the external surface of the existing pipeline. The seal rings, seal ring retention assemblies, and the flexible reinforcement pipe, accommodate out-of-round and joint angular displacement conditions of the existing pipeline. A self-hardening medium is injected into the annular space and pressure is maintained on the medium until the medium has set.

    Abstract: A conduit system having a conduit with an elongate body having a length between spaced first and second ends and bounding a passageway for communication of flowable material between the first and second spaced ends. The conduit has first and second end fittings connected respectively at the first and second ends of the body. An elongate element has a length and extends between the first and second ends of the body. The elongate element has a construction that resists elongation under applied lengthwise tensile forces to a greater extent than the body. The elongate element is connected to each of the first and second end fittings and is substantially unconnected to the body over a substantial length thereof so that elongation of the body is resisted by the elongate element.

  • Patent number: 8353317
    Abstract: An arrestor for arresting an axial ductile propagating fracture in a pipeline transporting a high-energy fluid is made from a material such that the arrestor deforms sufficiently when encountering a propagating fracture that the propagating fracture continues at least under the arrestor but the arrestor has enough strength that it ceases the crack propagation without ring-off of the pipeline. The material is filled with fiber characterized by having a stress-strain curve that passes thru the ranges between about 25 and 200 ksi in stress, and a deformation ranging from between about 5% strain and 35% strain, and having a diameter ranging between about 0.002 and 0.020 inches.

  • Publication number: 20120118424
    Abstract: A reinforcement and method for reinforcing a hollow tubular structure includes a first sheet of flexible fiber material impregnated with resin. The first sheet is rolled into a tubular shape and a seam is provided between first and second lateral edges of the first sheet to form a tubular reinforcement. An inflatable bladder extends through the tubular reinforcement and is inflated to press the tubular reinforcement into contact with the inside wall of the tubular structure. Curing of the resin will bond the first sheet to the inside wall to reinforce the tubular structure. The first sheet can have a region of built-up thickness to provide additional reinforcement. The seam between the lateral edges of the first sheet can be a separable seam that separates when the bladder is inflated to allow the first sheet to contact with a region of the tubular structure that is of larger circumference than the circumference of the tubular reinforcement.
