FIELD: study of materials. SUBSTANCE: process of determination of serviceability of pipes of steam superheater consists in cutting of at least one sample of pipe in most probable failure zone, in measurement of its diameter, in testing sample for flattening and in prediction of serviceability by results of test. While flattening sample is so placed that its side corresponding to front side of pipe is positioned in zone of compression. Test for flattening is conducted till first crack in scale in compression zone appears and serviceability of pipe is judged by deformation of sample in this zone. EFFECT: improved efficiency of process. 2 dwg, 2 tbl
