The possibility of assessing parameters of a stressed state from changes in magnetic properties is considered. Such an option would allow determining the sign and magnitude of the effective stresses. Generalized indicators of the stress state of a pipe cross section may include data on maximum, minimum, and average 'pointlike' stress in the investigated cross section, the amplitudes of extreme values, and the average stresses in the segments of the investigated cross section. It is shown that application of such generalized characteristics of a pipeline stress state allows one to sequentially change the scale (selection) of the evaluated segment and compare technological-equipment units through the use of the advantages of the local testing of stresses in combination with averaged parameters of a pipeline segment that has a respective scale.
