摘要:
为了开发更远地区的油气资源,研发了X120级UOE管线钢管。X120级UOE管线钢采用低Pcm的低C-Mn-Ni-Mo-Nb-V-B设计,其细小的奥氏体/马氏体和下贝氏体组织,具有优越的强韧性匹配;低Pcm值使该X120级UOE钢管焊缝热影响区具有良好的止裂性能。通过全尺寸静水压爆破试验对X120管线管的变形行为进行了研究,结果显示,高匹配的焊缝金属完全满足X120钢管的爆破试验要求;对静水压试验过程起裂点附近应变的测试结果显示,起裂从焊趾部位开始时,母材金属仅发生了很小的塑性应变,而此时HAZ的屈服强度已完全超过X120钢管的设计要求,且没有发生任何无规则的变形,充分证实了X120钢管的抗变形能力。
Abstract:
To enable the development of remote gas sources, X120 grade UOE line pipe has been developed. Low carbon-low Pcm and Mn-Ni-Mo-Nb-V-B pipeline steel with a microstructure of fine ausformed martensite and bainite has excellent combinations of strength and toughness. The weld HAZ of X120 UOE pipe is with good crack resistance due to a low Pcm. Deformation behaviors of the X120 line pipe were investigated through full size hydrostatic burst testing, the results verify that the over-matched weld in the X120 steel pipe can fully satisfy burst testing requirements. The strain test results near to the initial cracking point during the hydrostatic burst testing showed that the crack initiated at the weld toe, only a slightly plasticity strain in the base metal was observed, and the yield strength of the HAZ was higher than that of X120 steel pipe design requirements, and without any irregular deformation in the pipe. These performances fully verify the deformation resistance of X120 steel pipe.
