To achieve high abnormality detection precision of a tubular body.SOLUTION: An abnormality detection program makes a computer execute the following processing of: calculating a second temperature Ti of each of a plurality of tubular bodies on the basis of first temperatures of a plurality of measurement points in each of the plurality of tubular bodies; determining whether an overall running state of the plurality of tubular bodies at a first time point is a steady state or a transient state on the basis of a third temperature T across the plurality of tubular bodies acquired on the basis of the second temperature Ti of each of the plurality of tubular bodies at the first time point; and determining the second temperature Ti of each of the plurality of tubular bodies under the running state determined as the steady state as a processing object of abnormality detection processing of detecting an abnormality of the plurality of tubular bodies.SELECTED DRAWING: Figure 11 【課題】管体の異常検知精度を向上させる。【解決手段】複数の管体のそれぞれにおける複数の測定箇所の第１温度に基づいて、前記複数の管体のそれぞれの第２温度Ｔｉを算出し、第１の時点における前記複数の管体のそれぞれの前記第２温度Ｔｉに基づき取得される前記複数の管体全体の第３温度Ｔに基づき、前記第１の時点における前記複数の管体全体の運転状態が定常状態及び過渡状態のうちのいずれの状態であるかを判定し、前記定常状態であると判定した運転状態の前記複数の管体のそれぞれの前記第２温度Ｔｉを、前記複数の管体の異常を検知する異常検知処理の処理対象に決定する、処理をコンピュータに実行させる。【選択図】図１１
