| Abstract: | Seamless pipe for undersea oil pipeline is pre-produced with Q345B low alloy high strength structure steel and the control of chemical content and rolling process on pipe performance is analyzed in this paper. The result shows that it can meet requirement with Q345B low alloy high strength structure steel. It is also pointed that the proper control range and controlling end-rolling temperature is the effective method to upgrade pipe performance. |
