Abstract

Abstract: Assessment methods of failure of polyethylene (PE) gas pipelines have been introduced, and the failure analysis and mechanism study on PE gas pipelines were discussed. It was observed that the failure of polyethylene gas pipeline was usually assessed by mechanical testing, nondestructive testing was seldom employed. Future research direction and contents in nondestructive testing for PE gas pipelines were also anticipated.
