Small amount of steam in pipe does not state transfer well under liquification temperature

I have a 68 gram block of steam in a non insulated gas pipe. It was stuck for some time due to a broken pipe and I've released it. It's in the set of piping in the oil biome, making its way upward, in the save attached to

This might be a related issue as far as calculations under a certain weight, but it does have heat transfer and cools/heats during its transition through the piping. I expect it at some point to break the pipe and leak out as water, but it does not.
