METHOD FOR PRODUCING CUT ARTICLE, PRODUCTION SYSTEM, AND CUT ARTICLE
[Problem] To efficiently mark a cut article using comparatively simple equipment regardless of the length of the cut article. [Solution] A band-form steel band member 2 (continuous member) that is wound into a roll is drawn out and guided to a transport path 3. The transport path 3 transports the steel band member 2 that extends in the transport direction. A marking device 5 repeatedly marks the continuous member 2 on the transport path 3 with mutually different unique identification information so that the identification information is aligned at predetermined marking intervals. The steel band member 2 on which the identification information is marked is repeatedly cut by a cutting machine 8 at desired lengths, which are integral multiples of the marking interval, thereby creating a plurality of types of steel pipe 4 (cut article) of different length. A sensor 10 reads identification information marked at predetermined positions on the steel pipes 4. The read identification information is recorded in a management database 14 as identification information for individually managing the steel pipes 4.

[Problems] To provide a process for producing a thermal sprayed, metal plated steel tube having a metal layer substantially uniform and favorable over the whole surface in a highly productive manner.
[Means for solving] A process for producing a metal tube comprising continuously forming a metal plate composed of a first component into a tubular shape and continuously welding its butted ends to form the metal tube, wherein, after the continuous welding, a metal layer composed of a second component which is different from the first component is formed by thermal spraying directly over the surface of the metal tube, the metal layer having no discontinuities in the circumferential and lengthwise directions. Especially it is preferred that the process comprises a process step of making the thickness distribution of the metal layer more uniform after formation of the thermal sprayed metal layer over the external surface.
