- 摘要:
为研究在役天然气管道掺氢输送时管材的适应性,提出了基于ASME B31.12—2019 Hydrogen piping and pipelines、CGA G5.6—2005 Hydrogen pipeline systems及挪威船级社(Det Norske Veritas,DNV)、European Pipeline Research Group(EPRG)、Hydrogen Readiness for Gas Networks(HYREADY)联合工业项目(Joint Industry Project,JIP)等指南性文件的评价方法。分析了壁厚适应性评价、氢环境相容性评价、常规力学性能评价等管材适应性评价关键因素;壁厚适应性评价是通过对地区等级、高后果区以及强度试压情况的复核,确定合适的最大允许操作压力;氢环境相容性评价主要是通过试验手段进行验证,当氢脆敏感性低于50%、氢脆临界应力强度因子KIH不小于 55 MPam、疲劳预期寿命大于设计寿命,失效评估图处于安全状态时,可以判断管材适用。建立了适应性评价流程,通过工程实例开展了管材适应性评价并得出了评价结果。研究成果为在役天然气管道掺氢输送管材的适应性评价提供了参考。
In order to investigate the adaptability of in-service natural gas pipelines for hydrogen transportation, an adaptability evaluation method is proposed, based on ASME B31.12—2019 Hydrogen piping and pipelines,CGA G5.6—2005 Hydrogen pipeline systems, and with reference to Det Norske Veritas(DNV), European Pipeline Research Group(EPRG), the Hydrogen Readiness for Gas Networks(HYREADY) Joint Industrial Project and other guiding documents. The key factors such as wall thickness adaptability evaluation, hydrogen environmental compatibility evaluation and conventional mechanical property evaluation were analyzed. The adaptability evaluation of wall thickness is used to determine the appropriate Maximum Allowable Operating Pressure (MAOP) by reviewing the location class, high-consequence areas and results of the hydrostatic strength test. Hydrogen environmental compatibility evaluation is mainly verified through experimental methods. When the hydrogen embrittlement sensitivity is less than 50%, the critical stress intensity factor KIH is not less than 55 MPam, the fatigue life expectancy is greater than the design life, and the Failure Assessment Diagram (FAD) remains in a safe state, the pipeline material can be considered suitable. The process of adaptability evaluation is established, and the main contents and results of the evaluation are obtained in detail using engineering cases. This study provides reference for the adaptability evaluation of pipeline materials in in-service natural gas pipelines for hydrogen transportation.
