| Abstract: | In the process of manufacturing thread of oil casing,there are flaws of thread. By the macro - examination for gas content and hot acid of tubes, as well as the micro - analysis with metallurgical microscope and electron microscope, the results indicate non -metal inclusions are the main causes for flaws of thread. In the paper,the qualitative analysis of inclusions is made ,and their sources are found. Moreover, the appropriate improvement measures are proposed. |
