【摘要】:依照英國(guó)BS7448和挪威船級(jí)社DNV-OS-F101標(biāo)準(zhǔn)對(duì)管壁厚18.0 mm的X70級(jí)氣體保護(hù)焊環(huán)焊管熱影響區(qū)進(jìn)行斷裂韌度CTOD(crack tip opening displacement)試驗(yàn),并應(yīng)用數(shù)理統(tǒng)計(jì)方法對(duì)試驗(yàn)結(jié)果進(jìn)行了分布擬合檢驗(yàn).文中分別采用了柯爾莫哥洛夫檢驗(yàn)法和A2-W2檢驗(yàn)法對(duì)試驗(yàn)結(jié)果進(jìn)行了擬合檢驗(yàn)和對(duì)比分析,得到了該X70鋼焊接接頭熱影響區(qū)CTOD分布規(guī)律.結(jié)果表明,應(yīng)用A2-W2檢驗(yàn)法進(jìn)行擬合檢驗(yàn)的敏感度較高,且斷裂韌度數(shù)據(jù)擬合較好的統(tǒng)計(jì)分布函數(shù)為Weibull分布函數(shù),可結(jié)合歐洲工業(yè)完整性評(píng)定程序(SINTAP)的可靠性評(píng)定方法,計(jì)算得X70鋼焊接接頭熱影響區(qū)CTOD斷裂韌度概率密度分布函數(shù).
[Abstract]:According to BS7448 of England and DNV-OS-F101 standard of Norwegian Classification Society, the fracture toughness CTODG crack tip opening displacement) test was carried out on the heat-affected zone of gas shielded ring welded pipe with a wall thickness of 18.0 mm. The distribution fitting test of the test results was carried out by means of mathematical statistical method. In this paper, Colmogorov test and A2-W2 test are used to test and compare the test results, and the CTOD distribution in the heat-affected zone of the X70 steel welded joint is obtained. The results show that the statistical distribution function of fitting test with A2-W2 method is Weibull distribution function, which can be combined with the European Industrial Integrity Assessment Program (SINTAP), and the reliability evaluation method is Weibull distribution function, and the statistical distribution function of fracture toughness data is Weibull distribution function, which can be combined with the reliability evaluation method of European Industrial Integrity Assessment Program (SINTAP). The probability density distribution function of CTOD fracture toughness in heat affected zone of X70 steel welded joint was calculated.
