Wherein: the serial number in the report corresponds to the serial number displayed in the square frame on the drawing, and the displayed content in the report is the serial number and the pipeline information. The pipeline information comprises a medium code, a unit number where the pipeline is located, a pipeline number, a nominal diameter of the pipeline, a pipeline grade and a pipeline heat preservation code. Each pipeline is composed of a plurality of branch pipes, when a flat section is drawn, the system marks the serial number of each branch pipe, and meanwhile, the information of each branch pipe is loaded into a report, and the information of some branch pipes is completely the same.
