PROBLEM TO BE SOLVED: To provide a clinker transport piping life control system and life control method allowing the planned replacement of clinker transport piping of a thermal power plant. SOLUTION: The life control system has a means for determining wear speed depending on each position of the transport piping when the inside of the transport piping wears with time due to transportation of clinker, and a means for determining the average wear speed when the inside of the transport piping wears on the average based on each wear speed corresponding to each position of the transport piping. The life of the transport piping when rotating the transport piping timely is determined based on the average wear speed and the minimum demand wall thickness value of the transport piping, and the present wall thickness of each position of the transport piping is estimated based on the wear speed depending on the position of the transport piping. The rotation angle of the transport piping during rotating work is determined based on the estimated result of the present wall thickness of each position of the transport piping.
