- 摘要:
- CO2管道运输以密相/超临界状态为主,CO2管道泄漏会引起复杂相变,带来温度骤降,控制低温环境下的止裂韧性是对CO2管道用钢管的核心要求。为了研究CO2管道用钢管止裂韧性,从CO2管道标准研究角度对DNVGL RP F104—2021《CO2管道的设计与运行》(Design and operation of carbon dioxide pipelines,以下简称DNVGL RP F104—2021)、ISO 27913—2016《CO2捕集、输送和地质封存管道运输系统》(Carbon dioxide capture, transportation and geological
storage—Pipeline
transportation systems,以下简称ISO
27913—2016)、CSA Z662—2023《石油和天然气管道系统》(Oil and gas pipeline systems)和GB/T 42797—2023《CO2捕集、输送和地质封存管道输送系统》等国内外CO2管道标准钢管止裂韧性技术要求进行对比分析,介绍了钢管止裂韧性研究方法及进展。结果表明,可以采用ISO
27913—2016与DNVGL RP F104—2021的推荐方法,用互补验证的方式进行验证评估,以得到相对保守的止裂韧性指标。可充分分析研究国外先进标准,并结合国内最新研究成果,制定中国CO2管道用钢管标准,促进管道建设发展。
CO2 pipeline transportation is primarily in dense phase or supercritical state. Leakage of CO2 pipeline will cause complex phase change resulting in sudden temperature drops. Controlling crack arrest toughness to mitigate cracking at low temperature is the main requirement for steel pipes used in CO2 pipelines. In order to study the crack arrest toughness of steel pipes for CO2 pipelines, this research compares and analyzes the technical requirements for crack arrest toughness in CO2 pipeline standards at home and abroad, including DNVGL RP F104—2021 Design and operation of carbon dioxide pipelines(hereinafter referred to as DNVGL RP F104—2021), ISO 27913—2016 Carbon dioxide capture, transportation and geological storage—Pipeline transportation systems(hereinafter referred to as ISO 27913—2016), CSA Z662—2023 Oil and gas pipeline systems, and GB/T 42797—2023 Carbon dioxide capture, transportation and geological storage Pipeline transportation systems, from the perspective of CO2 pipeline standards research. The study also introduces methods and progress in steel pipe ductile fracture research. Results show that a complementary validation approach using methods recommended by both ISO 27913—2016 and DNVGL RP F104—2021 can be selected to obtain relatively conservative crack arrest toughness index. It is recommended to thoroughly study and analyze advanced international standards while incorporating the latest domestic research findings to develop standards for steel pipes used in CO2 transportation pipelines and promote pipeline construction development in China.
