In addition, the biggest advantage of this embodiment is that in the steel pipe product inspection stage, the steel pipe parameter measurement module is smoothly integrated, which not only measures the weight and length of the steel pipe in one step, but also uses it to match the quality flow data in the frame number, thereby reducing the error rate , and these measurement data are also used for quality control, and for refined management to manage the quality of steel pipes to each piece. Although the management from the frame number to the branch has made a qualitative leap in the existing steel pipe production management level, this embodiment also achieves the real-time application of these measurement data to ID parameter spraying and scale spraying. It should be noted that these test data and many steel pipe data and serial numbers appearing in Example 1 are all input into the database.
