| Abstract: | The trial produced process of 120mm dia round pipe for N80 oil pipe with 42MnO7 is presented. Through the analysis and test of the macroquality, chemical constitution and microscopic structure, it is showed that the surface and internal quality of billet produced with Baotou Steel CC process is good, which can produce the qualified round pipe. |
