3.6.1 Consideration of Cold Spring
Cold spring is the process of offsetting (or pre-loading) the piping system with displacement loads (usually accomplished by cutting short or long the pipe runs between two anchors) for the purpose of reducing the absolute expansion load on the system. Cold spring is used to: hasten the thermal shakedown of the system in fewer operating cycles reduce the magnitude of loads on equipment and restraints, since often, only a single application of a large load is sufficient to dam
