    Abstract: A heat conduction system including modular pipes housing a solid heat conductor made of a combination of carbon foam glass and grapheme and, for conductors, insulated from the outermost pipe by an insulating layer and with an annular gas purging gap for high-temperature applications. Also included in the system are thermal valves, manifolds, and heat exchangers to route and use the thermal energy. In an exemplary use, a down-hole heat exchanger, thermally coupled to a string of heat conduction modules, brings geothermal heat up from abandoned oil wells to operate a boiler and steam turbine. In another exemplary use, waste heat is conducted out of slag for conversion into useful energy. In yet another exemplary use, waste heat is conducted away from a nuclear reactor.

  • Publication number: 20150129315
    Abstract: An apparatus, system, and method of fabricating a percussion tool that includes a flow tube. The flow tube includes upper and lower portions, inner and outer walls, and at least one opening formed in the outer wall. The upper portion extends from a top end towards a bottom end. The lower portion extends from the upper portion to the bottom end. The inner wall extends from the top end to the bottom end and defines a central channel therein. The outer wall extends from the top end towards the bottom end, surrounds a portion of the inner wall and defines an outer channel with the inner wall. The opening is fluidly communicable with a first conduit formed within a piston, which surrounds a portion of the flow tube, when in an up position and is fluidly communicable with a second conduit formed within the piston when in a down position.

  • Patent number: 9016301
    Abstract: A conduit protection system, comprising: a conduit for carrying a fluid; a sealed vessel surrounding the conduit along a protected zone of the conduit; and a valve moveable between a first position for obstructing fluid flow through the protected zone of the conduit and a second position for enabling fluid flow through the protected zone of the conduit, wherein the valve is biased to the first position, and wherein the valve is fluidically coupled to the sealed vessel such that a positive pressure within the sealed vessel is operable to move the valve to the second position against the bias. Also, a method for protecting a fluid carrying conduit.

  • Patent number: 8978711
    Abstract: When the common part of the outer pipe and the inner pipe is worked with the pressing-type punching-out work for connecting with the inner pipe, there occurs no possibility that any disadvantage caused by the punched-out debris is generated. An inner pipe is arranged at the inside of an outer pipe. Each part of the outer pipe and the inner pipe is partially made common and integrally formed to each other. The inner pipe has the side walls extending from a common part of the outer pipe and the inner pipe to the diametral direction of the outer pipe in parallel and the recess wall facing the common part of the outer pipe and the inner pipe at a deep end of the side walls is not expanded more than the space between the side walls.

  • Patent number: 8967206
    Abstract: A process for producing a fluid conduit by forming a fluid delivery channel along the outer surface of a first elongate tubular body member. A second elongate tubular body having an inner circumference is fitted about the outer circumference of the first tubular body so as to seal the at least one fluid delivery channel on the outer surface of the first tubular body. A section of the fitted first and second tubular assembly is removed therefrom so as to define a fluid delivery channel in the form of a sealed fluid conduit.

  • Patent number: 8950071
    Abstract: During the manufacturing of heat-insulated pipes (1) with an inner duct (3) and an outer duct (2) and a foamed insulation (14) arranged in between, the inner duct is placed on a tension member (10). The latter is tensioned between tensioning means by means of a tensile force, such that it runs straight and that the inner duct is held straight. The latter is held on centering elements (16, 17) which are spaced from one another in a defined way by means of spacers (18). In this straight position the inner duct may be surrounded with foam inside of the outer duct, without needing spacers between the ducts.
