I'm used to seeing cryogenic pipes insulated but maybe this is how regasification is normally done..there's a cryogenic line, client wants contents to vaporise downstream so it's uninsulated. A very thick layer of ice forms all around the pipe.
Common sense tells me that besides the added weight, the ice increases the equivalent modulus of elasticity of the pipe (similar to refractory lined pipe). Is there anything wrong with this logic?
Maybe if the pipe chills quickly and the ice mostly comes after the chilling it can be argued that there's little effect in the cold condition apart from weight. But if fluid flow stops and the pipe warms up the ice would then fight the return to neutral position. The ice will melt and crack but not before imposing significant loads i would think.
Does anyone have relevant design experience or counter arguments ?
