摘要
介绍了ASME B31.8S-2001(天然气管道完整性管理)中采用的危险区域预测模型,该模型由火灾模型、气体释放速率模型和热强度阈值3部分组成,它表明了高压天然气管道断裂后,危险区域与管线直径、运行压力的关系。
This paper introduces the dangerous areas prediction model in ASME B31.8S-2001 （ integrity management of natural gas pipelines）. This model consists of fire model, release model and heat radiation threshold. It shows the relation between dangerous areas and pipelines＇ diameter and operation pressure.
