摘　　要：为满足在酸性服役条件下输送油气的要求,设计出化学成分合理的L245NCS钢,通过对各工序特别是热处理工序的严格控制,开发出满足用户要求的具有良好组织和力学性能、抗HIC和SSC的L245NCS钢石油天然气输送用管。简要介绍了该产品的化学成分和工艺设计、生产工艺以及检测结果。To satisfy the requirement for oil/gas transport under acidic operation conditions, the L245NCS steel is produced with its chemical composition well designed. With all the operation steps, particularly the heat treatment process strictly controlled, the HIC and SSC L245NCS steel oil/gas linepipes in possession of good structural and mechanical properties are developed. Briefed in the paper are the main aspects of the said linepipe, including the chemical composition, technological design, manufacturing process as well as relevant testing/inspection results.
