SUMMARY This paper reports on a series of temperature runs on a high-pressure, high-temperature bolted flanged joint. The work was done in the mechanical engineering laboratory at the Johns Hopkins University during 1949. Bolt stresses were computed from temperature measurements in the bolts and flanges. A stream of hot gases was introduced in the line containing the flange, the stream temperature ranging from 600°F to 1200°F. The Reynold's Number varied from 10,000 to 20,000. The temperature differential between the flange and bolts was found to be small in all cases, and linearly related to the stream temperature. The findings are contrasted with those reported earlier by some German engineers. |
