Utilizing the basic principle of exergy economics, the steam transportation process in the heating steam pipe is analyzed, and the annual total cost equation of the heating steam pipe is obtained. This equation can be used to analyze the pipe diameter and thickness of the heating steam pipe And other factors on the total cost of the year; at the same time, the proposed heating pipe and its insulation layer of the synchronous design method, reducing the cost of transporting steam from the point of view, get the best diameter and the optimal insulation thickness formula , The results for engineering design reference.
