ABSTRACT:
The production history information management apparatus100comprises: machining an identifier for identifying a pipe or tube in a region of the pipe or tube on which thread cutting is to be performed before an initial production process is performed among production processes which are management targets of the production history information; reading the identifier machined on the pipe or tube before each of the production processes is performed or while each of the production processes is performed; management for storing the production history information of the pipe or tube obtained in each of the production processes and the identifier read from the pipe or tube while the production history information and the identifier are associated with each other; and thread cutting for removing the identifier machined on the pipe or tube in the process of performing the thread cutting on the end portions of the pipe or tube among the production processes which are management targets of the production history information.
