| 摘 要： | 介绍了渤海石油装备制造有限公司钢管制造公司X80钢级φ1 219mm感应加热弯管用母管采用的国内生产的两种钢板（钢A和钢B）的性能，以及采用JCOE工艺用钢A和钢B试制感应加热弯管用直缝埋弧焊母管的性能。通过对比试验分析，提出了X80钢级φ1 219mm感应加热弯管用母管的化学成分要求，结合感应加热弯管在二次热加工工艺过程中（感应加热弯制＋全长、部分淬火＋整体回火）的硬度变化特点，建议对国内相关感应加热弯管标准中的硬度要求进行调整。

| Abstract: | Described are the properties of the home-made steel plates (i.e.,Steel Plate A and Steel Plate B) as used to make X80 Φ1 219 mm pipe as blank for pipe bent with induction-heating process,and the proper-ties of the SSAW pipe made in Steel A and Steel B and by the JCOE process to be used for the same purpose. Thanks to the result of relevant comparative test analysis,chemical composition requirement for the above men-tioned X80 Φ1 219 mm mother pipe is worked out. Based on the said requirement together with the hardness vari-ation characteristics of the pipe bent in the secondary heating process (i.e.,bending with induction heating + over-length or partial quenching + entire body tempering),it is proposed to make some revision of hardness re-quirement as set in relevant domestic applicable standard for pipes bent with induction heating process. |
