Dear teachers: What does the pipeline grade code BAN1R mean, and in which standard is this notation specified? Please advise. I am extremely grateful.

BAN1R represents the grade code of the pipe, where BAN indicates the material and manufacturing standard of the pipe. The specific meanings are as follows: B: indicates steel pipe; A: indicates carbon steel; N: indicates no reduction in diameter or pits; 1: indicates that the pipe belongs to grade 1, with a wall thickness of Sch40; R: indicates hot-rolled. This notation system is specified in the American ANSI B36.10 standard and is primarily used for identifying and classifying pipes. .

Thank you. Could you provide a Chinese version of ANSI B36.10?
