Development of high-temperature biaxial-strain transducer for use to 1033°K (1400°F)

This study involved the development and evaluation of a high-temperature biaxial-strain transducer for measurement of strains up to 5 percent at temperatures approaching 1033°K (1400°F). The design requirements for transducer were established by specifications prepared by the Pressure Vessel Research Committee (PVRC) of the Welding Research Council. These specifications reflect the needs of the national laboratories and private industry as they relate to safety and structural-behavior studies of nuclear and advanced fossil-fuel systems, including piping, piping components, heat exchangers, and other pressure equipment. It was concluded, on the basis of the results from this study, that the transducer should perform satisfactorily at temperatures to at least 866°K (1100°F), and perhaps to 1033°K (1400°F). This paper should be of particular interest to those involved in high-temperature strain measurements or structural-behavior studies of energy systems (nuclear and fossil fuel) and components (piping, pumps, valves, heat exchangers, reactor components, etc).
