This paper presents one of the possible hazardous situations during transportation of gas through the international pipeline. It describes case when at high pressure gas pipeline, due to mechanical or chemical effect, the crack and gas leakage appears and gas is somehow triggered to combusting. As a consequence of heat impingement on the pipe surface will be, change of material properties (decreasing of strength) at high temperatures. In order to avoid greater rapture a reasonable pressure relief rate needs to be applied. Standards in this particular domain of depressurizing procedure are not so exact (DIN EN ISO 23251; API 521). The main part of the work consists of two calculations. First is the numerical simulation of heat radiation of combustible gas which affects the pipeline, done by software FLUENT, and second in Matlab. There are also given conclusions according to achieved results.
