摘要:
回顾了管线裂纹止裂研究的成果,通过实物试验分析表明,20世纪70年代的止裂公式在确定高韧性管线的止裂行为上已偏于危险。结合西气东输二线工程工况,提出了断裂韧性指标确定的原则和基本要求。根据不同标准对延性止裂的论述,通过止裂韧性研究,确定了西气东输二线用管止裂所需的韧性指标。
Abstract:
It is reviewed that research achievement of pipeline cracks arrest,It shows that the formula of pipeline crack arrest in 1970s was inclined to danger for determining cracks arrest behavior of high toughness pipeline through objects test.Combining with operation condition of the second east to west gas pipeline project,it puts forward principle and basic requirements to determine fracture toughness indexes.Through research of crack arrest toughness,toughness indexes required by crack arrest of steel pipe for the second west to east pipeline project is determined in accordance with discussion about ductile crack arrest in different standards.
