Radial contraction for tank roof nozzles - 11/13/07 08:51 AM
I have a case where there is 36.o m cryogenic tank. Number of big bore 10", 16" lines run parallel to tank shell and get connected to nozzles on tank roof . The nozzles are placed on circle of 12.0 m radius on tank roof. Tank temperature is -65 Deg. C.
The radial contraction of nozzles towards tank centre is considerable and whether needs to be considered in the analysis ?
What is normal practice ?
For shell nozzles of tanks, especially on lower tank shell course, some engineering companies neglect radial contraction.
ANY OPINIONS PLEASE.
