摘要:
为了进一步提升高频电阻焊套管的韧性,实现母材与焊缝“等韧性”匹配,采用高频焊+全管体调质热处理工艺试制N80钢级Φ244.48 mm×11.05 mm套管,并对试制产品进行性能检测评价。结果表明,管体的几何尺寸、理化性能和全尺寸实物性能均满足相关标准要求,且经全管体调质处理后,HFW套管的焊缝、热影响区和母材组织性能差异较小,基本实现了焊缝与母材“等韧性”匹配,同时套管尺寸精度较高,性能均匀,具有良好的抗挤毁性能,为油田客户降本增效提供了产品保障。
Abstract:
In order to further improve the toughness of high frequency electric-welded oil casing and realize the matching of base material and weld equal toughness,the N80 steel grade Φ244.48 mm ×11.05 mm oil casing was successfully trial-produced with the manufacturing process of high-frequency welding and fullength quenching-tempering treatment.The result shows that the geometric dimensions,physical and chemical properties and full-scale test are all meet the requirements of the standards. After the whole pipe quenching and tempering treatment,the difference between the weld,heat affected zone and base metal structure and performance of HFW casing is small,which basically realizes the equal toughness matching between the weld and base metal. At the same time,the casing has high dimensional accuracy,uniform performance and goodcollapse resistance, providing product guarantee for oilfield customers to reduce costs and increase efficiency.
