Abstract
Apparatus for conducting fluid and preventing its icing have a fluid line structure and a tubular fluid line element located in that fluid line structure and having a cross-section sufficient for a desired throughput of fluid. A heater element is located inside the fluid line structure and is in heat-transfer relationship with an inside of the tubular fluid line element. Such heater element may be an electric heater element inside the fluid line structure encompassing the tubular fluid line element in heat-transfer relationship with an inside of that tubular fluid line element. A frangible or other fluid line nipple may be removably connected to the fluid line structure, and the tubular fluid line element may extend from that fluid line structure to that fluid line nipple. A heat transfer reduction may be provided between the electric heater element and the fluid line structure outside of the tubular fluid line element.
