| Abstract: | 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. |
