摘要:

综述了聚乙烯(PE)管道的失效模式和失效准则,总结归纳了4种管道寿命预测方法,包括基于长期静液压试验法、基于Arrhenius公式法、基于慢速裂纹扩展(SCG)法和基于双曲本构方程法;概述了5种管道风险评估方法,包括专家评分法、事故树分析法、管道指数风险评分法、层次分析法和模糊综合评价法。未来可建立力⁃化耦合作用下的有限元分析模型,结合大数据分析和管道风险评估方法,保障在役PE管道的安全运行。

关键词: 聚乙烯管道, 失效模式, 失效机理, 寿命预测, 管道风险评估

Abstract:

This paper reviewed the failure modes and failure criteria of polyethylene (PE) pipelines and summarized four pipeline life prediction methods, including the long⁃term hydrostatic test method, Arrhenius formula method, slow crack growth method, and hyperbolic constitutive equation method. Five pipeline risk assessment methods were summarized, which included expert scoring method, fault tree analysis method, pipeline index risk scoring method, and analytic hierarchy process and fuzzy comprehensive evaluation method. In the future, a finite element analysis model under the force⁃chemical coupling action should be established through combining with the big data analysis and pipeline risk assessment methods to ensure a safe operation for the in⁃service PE pipelines.

Key words: polyethylene pipe, failure mode, failure mechanism, life prediction, pipeline risk assessment
