How does one measure the amount of relaxation in high temperature pipes in thermal power plants?

Also which areas of say a main steam pipe will have more relaxation?

Where expansion and contraction are a problem, pipe hangars are spring loaded and a pointer and scale can be attached to measure the lateral movement at that point. Expansion joints, loops and u-bends are also used to absorb linear travel due to expansion. The amount or relaxation or expansion is dependent upon the temperatures and pressures involved and the material used for the piping. The hottest point in the system or the boiler outlet will be the most affected because there will be some thermal loss and pressure drop, however minute, in any system.
