Natural gas is considered one of the most important sources of energy currently available in the world, and Some difficulties face the process of transporting gas through pipelines, including terrain and stages that occur during the transportation process, and this study was based on simulating the transfer of the produced gas from three wells that were linked Together with a steel pipe network of different lengths and diameters from 3 to 6 inches and a total length of about 3274 meters connected to the main transportation pipeline with a diameter of 6 inches and by observing the change in heat loss caused by the piping network. It was shown a decrease in the amount of heat lost from the pipes as a result of wrapping these pipes with a layer of Asphalt with a thickness of one millimeter to avoid the occurrence of corrosion of the outer surface and to prevent the formation of hydrates, and with the continued flow of gas in the steady-state through the network. It was shown through the results obtained from the PIPSYS program. The flow pattern was an annular mist of all pipes. The final pressure of the last production line was also calculated after adjusting the operating pressure of well A with the pressure of the last production line until it reached the desired values of 6895 kpa, 34.61°C and a flow rate of 1300 kg mol per hour, as well as a decrease in the maximum head pressure drop this part, was -9.6 kpa And, by making some adjustments to the fluid package, i.e. by testing three models of state equations in the gas phase and all results were close, as well as calculating the phase diagram of pressure, temperature, and the ability to form hydrates in the outlet conditions of the last part of the network.
