文摘During manufacturing and storage of 3PE pipes,the end PE upwarp is a common phenomenon,and the gap corrosion will be easy to produce under the condition of poor atmosphere environment, which hazard the anti-corrosion quality of 3PE pipes and difficult to field coating for welded joints. The authors analyze the PE upwarp problem, and based on the analysis results the quality control measures are given for the manufacturing of 3PE pipes.
