N2  -  Despite the very good mechanical properties of composite materials, the strength of these materials is not suitable for heat resistance. Therefore, due to the increasing use of composite pipes, especially in the oil, gas and petrochemical industries, fire analysis in these pipes is very important. The most important goal of this research was to investigate the effects of fire on the strength of composite pipes and their failure time by performing a numerical thermal-mechanical analysis for a fluid-carrying composite pipe using MATLAB software. At the first step thermal modeling is carried out and heat distribution, due to the hydro carbonian fire, in the composite pipes is determined in terms of the location and time and then in the mechanical modeling stage, the loss of mechanical properties of the composite pipe due to this increase in temperature is calculated and considering the stresses from the fluid inside the pipe as well as thermal stresses have been created, the total stresses have been calculated. This Thermo-Mechanical model has been validated with the results found in valid articles and used to analyze the behavior of a fluid-carrying composite pipe exposed to hydrocarbon fire. Finally, the Tsai–Wu failure theory was employed to determine the failure time of the pipe in the above-mentioned conditions. By estimating the failure time of the composite pipe, it was possible to determine the pressure bearing capacity and failure time of pressurized composite pipes subjected to fire
