摘要
通过三组不同规格Ｔ／Ｓ５２Ｋ钢管的实物静水压爆破试验，探讨了钢管裂纹的扩展行为。试验结果表明：用夏比冲击韧性能很好地判断管道的止裂能力；
The static hydraulic pressure exploding
trials of three groups' different specifications T/S52K steel pipe are undertook. The extension
acting of steel pipe crack is discussed. The results demonstrate that the toughness property is
good at estimating the ability of stopping crack of pipes. The complex stress condition of spirally
welded pipe is one of the main factors that cause the crack to deflect after crack extending a
certain distance.
