The utility model discloses a gas pipeline of a gas station, which comprises a main pipeline and two branch pipelines. One end of each of the two branch pipelines is respectively connected with two gas outlets on a furnace top cover, and the other ends of the two branch pipelines are connected with the main pipeline. The gas pipeline is characterized in that each branch pipeline consists of two sections, an included angle between the two sections of each branch pipeline is an obtuse angle, and an included angle between the section, which is connected with the main pipeline, of each branch pipeline and the main pipeline is an obtuse angle. Due to the structure, blockage of the pipelines is reduced relatively, airflow smoothness is increased, gas yield is ensured, and the pressure of gas in a furnace is reduced. In addition, the diameters of the branch pipelines are enlarged, so that airflow is smoother.
