Hot Spring (and pipe stress analysis)

[Hurricanes]

I am currently doing a pipe stress analysis on some steam piping. The as built drawings show cold spring and it amount, but also shows hot spring in some areas.

Now I am well aware of cold spring and how to analyse it, but I have never come across hot spring. I had a quick glance through my copy of Pipe Stress Engineering by Peng and Peng and there doesn't seem to be a reference to it there.

Could someone please explain, or point me to a reference of what hot spring actually is? Is it simply the opposite of cold spring and the pipe is slightly longer as opposed to being cut shorter?

Sorry for the double post.

I have found a reference to 'cut long' being the opposite of cut short. I am assuming this is therefore hot spring?

The opposite of "Cold Spring" is commonly used in Cryogenic (very cold) piping and is called "Pre-Spring"
