D-Zero End Cap Calorimeter Annular Piping Analysis
In accoradnce with the ASME Code for Pressure Piping, B31 version of Chemical Plant and Petroleum Refinery Piping, ANSI/ASME B31.3-1984 Edition, the maximum allowable stress for 304 stainless steel piping is 25,500 psi. This 'Allowable Displacement Stress Range' value was calculated using equation (1a) found on page 16 of the above mentioned reference. Each of the lines that comprise the End Cap Calorimeter (BC) piping were modeled on ANSYS and the appropriate constraints were applied. This was done using the Piping Stress Analysis Module of ANSYS. The bending stresses and displacements due to the thermal contraction that occurs in cooling the piping from 300 K to 77 K were calculated by ANSYS. The seven lines involved and their maximum bending stresses are as follows: (1) Rupture Disc - Maximum bending stress is 8335 psi; (2) Argon Relief - Maximum bending stress is 12,619 psi; (3) Gaseous Argon Supply - Maximum bending stress is 5399 psi; (4) Liquid Nitrogen Cooldown Supply - Maximum bending stress is 7049 psi; (5) Liquid Nitrogen Operating Supply - Maximum bending stress is 5774 psi; (6) Nitrogen Exhaust - Maximum bending stress is 1826 psi; and (7) Argon/Nitrogen Vent - Maximum bending stress is 48,364 psi. …
