This may include a cutting step and a cutting step, and an inspection step of inspecting dimensions, appearance abnormalities, physical properties, and the like for the singulated pipe. In addition, a printing marking step for adding necessary information and the like to the tubular structure by printing and / or marking may be provided before or after the cutting and cutting steps and / or inspection steps.

In addition to the above description of the present invention is for illustrative purposes, those of ordinary skill in the art can understand that it can be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. There will be. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed or divided manner, and similarly, components described as distributed or divided may be implemented in a combined form within the understanding of those skilled in the art. have. In addition, each step of the method or the process may be carried out alone or in a plurality of times performed in combination with at least one other step.

The scope of the present invention is represented by the following claims, and it should be construed that all changes or modifications derived from the meaning and scope of the claims and equivalent concepts thereof are included in the scope of the present invention.
