Michael, by B31.3 319.2.4 Cold spring is the intentional deformation of piping during assembly to produce a desired initial displacement and reaction.

Cold Load of a spring support is a force applied to piping system in "cold" status.

It is true that literally "Cold Load of a spring support" can be shorten to "cold spring", however proceeding in this way we can speculate everything we want. Anyway, for me it's the same connection as to cold war and cold box...
