CO2管道标准钢管止裂韧性技术要求对比分析
Comparative analysis of technical requirements for mitigating CO2 cracking of standard steel pipeline
摘要
Abstract
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 CO 2 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 CO 2 transportation pipelines and promote pipeline construction development in China.关键词
