Two components in cryogenic equipment are held together by stainless steel (ASTM A437 B4B) bolts with diameter of 25 mm. The bolts have a thermal conductivity of 23.9 W/m. K, a specific heat of 460 J/kg .K, and a density of 7.8 g/cm". When the cryogenic fluid flows between the two components, the bolts are submerged in the cold fluid. The length of each bolt submerged in the cryogenic fluid is 5 cm, and the initial temperature of the bolts is 10°C. The cryogenic fluid has a temperature of -40°C with a convection heat transfer coefficient of 40 W/m².K. The ASME Code for Process Piping limits the minimum suitable temperature for ASTM A437 B4B bolts to -30°C (ASME B31.3-2014, Table A-2M). If the bolts are exposed to the cold fluid for 12 min, will they still comply with the ASME code? How long will it take for the bolts to reach the minimum suitable temperature?
