X100高压输送管线裂纹止裂预测探讨
Discussion on Forecasting Crack Arrest of X1O0 High Pressure Transmitting Pipeline
摘要
Abstract
Refer to the full scale burst test result of X100 high grade line pipe, it discussed the influence of flow stress and DWTT energy on crack arrest behavior of pipeline, studied the boundedness of current crack arrest prediction model to X100 high grade pipeline, and put forward M parameter prediction method (M=CVN1/2/YS). The analysis result showed that M parameter can forecast crack propagation and arrest of pipeline well Combined with flow stress, DWTT energy and M parameter, it can provide support for determing the key mechanical properties.关键词
