Method for realizing reliability maintenance planning of high temperature pipeline system

The invention relates to a method for realizing reliability maintenance planning of a high temperature pipeline system, which comprises the following steps of: collecting and acquiring detection data of a high temperature pipeline system; calculating a finite element of the high temperature pipeline system; determining creep damage parameters according to the influence degree of all factors on the life of the high temperature pipeline; creating a creep damage probability model through determining the probability distribution of the creep damage parameters; calculating a structural failure probability according to the creep damage probability model; creating a maintenance planning model based on reliability analysis according to the detection data, test results of materials and structures of the high temperature pipeline system and the structural failure probability; and carrying out calculation processing according to the maintenance planning model to obtain the optimal maintenance time of the high temperature pipeline system. By adopting the method for realizing the reliability maintenance planning of the high temperature pipeline system, the structural reliability is determined efficiently and accurately, a maintenance scheme can be accurately determined, the similar problem of the maintenance planning of the high temperature pipelines in other fields can be solved, and the method has wider application range.
