What does variability mean in pipe supports?

February 11, 2011

Variability applies to variable spring supports and is basically a ratiobetween the difference in load and the operating load of the spring. Thedifference in load is a function of the spring rate and travel. Per MSS, themaximum recommended variability would be 25%. However, critical systems such asmain steam supports may require variability factors less than 25%.
