Evaluation of high-temperature pipe insulations using a 16-in. -diameter pipe test apparatus
- Westinghouse Electric Corp., Pittsburgh, PA
The thermal performance of candidate pipe insulation systems for the sodium piping at the Fast Flux Test Facility (FFTF) in Richland, Washington, has been tested at pipe temperatures up to 838.7/sup 0/K (1050/sup 0/F) using a 40.64-cm (16 in.) pipe test rig. Where applicable, procedures outlined in the ASTM Test for Thermal Conductivity of Pipe Insulation (C 335-69) were followed. These tests have demonstrated the feasibility of measuring thermal performance using large-diameter, guarded pipe test systems. To compare and evaluate the large-diameter pipe test results, the thermal performance of these insulations was also measured by an independent testing laboratory on a 7.62-cm (3 in.) pipe test apparatus. Mineral wool, calcium-silicate, and aluminum-silica refractory fiber blanket-type insulations were evaluated on both the 40.64-cm (16 in.) and 7.62-cm (3 in.) pipe test apparatus.
