超高压聚乙烯管式反应器R401缺陷评定

DEFECT EVALUATION OF TUBULAR REACTOR R401 FOR SUPERHIGH PRESSURE POLYETHYLENE

参照英国 R6评定方法及美国 ASME规范第 篇 IWB-3 64 0 ,IWB-3 65 0等评定方法 ,结合断裂力学有关理论和材料的试验数据 ,对超高压自增强反应管进行了缺陷评定 。

In accordance with the English R6 evaluation method and the evaluation method of America ASME Code section XI,IWB 3640,IWB 3650 etc.,in combination with the relevant theory of fracture mechanics and material testing data,the defect evaluation of superhigh pressure self strengthen reaction tube was conducted.The fissure propagation life after non residual stress,and the conclusion,that the reactions tube leaks before fracture,were achieved.
