螺旋焊缝管的断裂特点
Fracture Features of Spiral Welded Pipes
-
摘要: 文章综述了国内外有关螺旋焊缝管的断裂试验和研究工作的概况。分析了螺旋焊缝管的断裂特点, 给出了不同情况下穿透性裂纹和非穿透性裂纹的起裂判据公式。强调指出了这一研究领域中应注意的问题, 并建议加强这方面的理论研究工作和国际交流活动。Abstract: The article is a general review of the test and research work on fracture in relation to spiral welded pipes at home and abroad. It points out the fracture features of such pipes, presenting the formulas for determining the initiation of fracture that may become piercing or nonpiercing under different conditions. It reiterates the problems worth our notice in this field and expresses hope to strengthen the theoretical research and international exchanges of views in this direction.
