DISCUSSION ON RELATIONS BETWEEN STRESS,THERMAL DISPLACEMENT AND RESTRAINTS OF MAIN STEAM PIPE[J]. Thermal power generation, 1992, (5): 45-50. DOI: 10.19666/j.rlfd.1992.05.008.
Based on field measurements on several utility boilers
the following problem were studied: (1) the tendency of stress variation in steam pipe during unit start-up; (2) the relations between pipe stress
thermal displacement and restraints; (3) the major causes for component failure in the piping system. The result of this study is of important reference for the design of piping system and for the residual life assessment as well.
