Due to its advantages of good toughness, corrosion resistance, low cost and constructability, etc., polyethylene (PE) pipeline is widely used in natural gas transportation. Because of the characteristics of PE pipeline, the material aging becomes a problem while using.The method for effectively and efficiently evaluating the aging performance of PE pipes in service has been highly concerned in the industry. There are differences in its aging condition due to differences in pipe diameter and material. It is found that the antioxidant capacity of PE pipes of the same PE material under the same SDR conditions increases with increasing pipe diameter as influenced by the wall thickness of the pipe. There are obvious differences in the antioxidant performance of PE pipes made from different materials; under the experimental conditions of this paper, the antioxidant performance of PE100 is significantly better than that of PE80.
