| Abstract: | The yield strength of X65 steel pipe is obviously decreased after pipe making. An analysis on the stress and strain of the pipe occurred in Bauschinger Effect test and pipe making process is made. The variation of yield strength before and after pipe making with imported steel plate is analyzed and discussed. |
