Abstract
A method of diagnosing a pipe includes diagnosing, by a computer, a state of a pipe from an updated model based on change in temperature of the pipe calculated from the model in a case where the pipe is heated in the model obtained by modeling a heat transfer behavior of an inside of the pipe containing deposition by using an equivalent circuit and change in temperature of the pipe measured in a case where the pipe is heated.
Claims11
A method of diagnosing a pipe comprising:
- diagnosing, by a computer, a state of a pipe from an updated model based on change in temperature of the pipe calculated from the model in a case where the pipe is heated in the model obtained by modeling a heat transfer behavior of an inside of the pipe containing deposition by using an equivalent circuit and change in temperature of the pipe measured in a case where the pipe is heated.
A device of diagnosing a pipe, the device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- diagnose a state of a pipe from an updated model based on change in temperature of the pipe calculated from the model in a case where the pipe is heated in the model obtained by modeling a heat transfer behavior of an inside of the pipe containing deposition by using an equivalent circuit and change in temperature of the pipe measured in a case where the pipe is heated.

A system of diagnosing a pipe, the system comprising:
- a heating device that heats a pipe;
- a measurement device that measures surface temperature of the pipe;
- and
- a processor that diagnoses a state of a pipe from an updated model based on change in temperature of the pipe calculated from the model in a case where the pipe is heated in the model obtained by modeling a heat transfer behavior of an inside of the pipe containing deposition by using an equivalent circuit and change in temperature of the pipe measured in a case where the pipe is heated.
