6月18日，太钢技术中心成功试制超临界二氧化碳输送焊管用热轧钢板，实现产品国内首用。并中标国内首条长度最长、管径最大、压力最高、输量最大的超临界二氧化碳管道项目。

超临界二氧化碳是维持在临界温度及临界压力以上的二氧化碳流体，具有高密度、低粘度、高扩散系数的特点。在31℃、7.38兆帕的温压条件下，二氧化碳以超临界态的形式存在，它既有气态性质又有液态性质，能快速溶解有机物，毒性低，对环境影响较小，是重要的商用以及工业溶剂。

随着“双碳”目标任务持续推进，碳捕集、利用与封存作为实现大规模碳减排的托底技术，对二氧化碳管道输送关键难题与核心技术提出了新要求，二氧化碳管道运行过程中，腐蚀穿孔或第三方破坏可能引发管道泄漏等安全问题，对管道设计、管道材料选择及完整性管理提出了挑战。针对管道高压、低温等技术需求，太钢技术中心等部门通过深入协作，研发出了具有合适强度、良好低温韧性和良好焊接性能的热轧产品，并与下游制管厂分别开展了一系列钢管焊接试验，经最终试制后，超临界二氧化碳输送焊管顺利通过第三方检测评价，低温冲击韧性等性能远优于项目要求。

二氧化碳输送管道在国外建设超2500公里，但国内尚无长输先例。该产品首次应用于国内首条超临界二氧化碳长输管道项目，将成为周边各碳排放企业与利用企业之间的干碳网，有力推动地区企业实现低碳转型，同时为我国未来二氧化碳输送管道建设储备了技术能力。
