| Abstract: | In this paper,the statistics and analysis have been made on the pipeline sections with the mechanical damage, human damage, and natural damage from Zhongyuan oilfield to Cangzhou gas pipeline. According to the technical requirements on the repair welding and corrosion control,the overhaul to this pipeline has been made. The 3-layer asphalt with 2-layer glass cloth has been used which is combined with 1-layer paint with 2-layer tape in the construction of anti-corrosion of the pipeline,and the accurate calculation on the pipe length of relowering-in and the its elastic curverture have been made. |
