Abstract: Embodiments include a thermally activated flow valve. The valve comprises a valve body defining an input portion and an output portion; and an expanding element disposed within the valve body; wherein the valve includes an open configuration and a closed configuration, when the valve is in the open configuration the input portion is in fluid communication with the output portion, when the valve is in the closed configuration the input portion is not in fluid communication with the output portion; wherein when the expanding element is exposed to a temperature above a threshold temperature the expanding element expands and terminates the fluid communication between the input portion and the output portion thereby transitioning the valve from the open configuration to the closed configuration.

Abstract: The present invention is directed to improved assembly for transporting flammable fluids. In an example, the assembly comprises a conduit, a liner, and a core. The liner comprises a material that contracts in response to an elevation in temperature. In an example, the liner comprises a material that expands in response to an elevation in temperature.
