description: Subject of the graduation paper: âBy diagnosing the main gas pipelines it assesses the state of the metals and the welded jointsâ. The paper deals with the diagnosing the state and assessing the condition of the operating main gas pipeline. The tasks of the graduation thesis: To do a literature study of types of controls during the diagnosis of the linear part of the main gas pipelines. To do a literature study on the potential causes of defects in the pipe metal and the welded joints. To conduct a study of the existing main gas pipeline. The works were carried out in the branch of Gazprom transgaz St. Petersburg Engineering and Technical Center. Full inspection by non-destructive control methods was made. On the basis of this survey the reports in Appendices 1, 2, 3, 4 are presented. In the appendices there are reports of general list of defects on the condition of the main gas pipeline, eddy current, magnetic particle testing and ultrasonic thickness gauging.
