| 摘 要： | 为了研究X120(827 MPa)钢管的爆破容量从而正确评估钢管的结构性能,进行了一系列的全尺寸试验和有限元分析,同时进行了爆破和断裂止裂研究,进行了全尺寸止裂试验以评估X120钢管材料本身的止裂能力。爆破试验和分析的结果表明,该X120钢管有很强的抗内压能力。试验所讨论的模型未预测到X120管线钢管固有裂纹止裂所需要的韧性,但是,在不太严格的设计情况下,对于有固有裂纹止裂能力的X120钢管可能具有足够的止裂韧性。

| Abstract: | A new high strength een developed for linepipe applications. Full-size pipe tests and finite element analyses were conducted to evaluate structural performance. The burst and fracture arrest studies were conducted. Results from burst tests and analyses demonstrate sufficient pressure containment capacity. For crack arrest, full-size tests were conducted to evaluate the intrinsic arrest ability of the material. The X120 may possess sufficient toughness for intrinsic arrest under less severe design scenarios. |
