摘要
介绍了HFW焊管机组的生产能力以及高钢级HFW石油套管的开发研制情况。经过一系列检测分析发现,通过调质热处理工艺研制出的N80Q、L80-1、P110钢级高强度HFW石油套管,其材料组织、强度、韧性等都发生了变化,力学性能达到了API Spec 5CT标准(第9版)要求,可满足用户的技术要求。分析认为:原料成分和调质热处理是实现高钢级HFW石油套管生产的关键。
Introduced here are the production capacity of the HFW pipe welding mill and the R ＆ D situation of high grade HFW oil casing. For N8OQ, L80-1 and P110 high strength HFW oil casings developed by quenching and tempering process, a series of tests and analysis found out that their material structure, strength and toughness ect. have all changed after quenching and tempering, and their mechanical properties meet the requirements of API Spec 5CT （9th edition） and satisfy the technical requirements of customers. The analysis indicates that material composition and quenching and tempering are the key factors for realizing the production of the high grade HFW oil casing.
