The invention relates to a full life circle management method of gas transmission and distribution equipment. The full life circle management method comprises the following steps of (S1) building an equipment information database corresponding to the gas transmission and distribution equipment; and (S2) carrying out real-time data collection on the gas transmission and distribution equipment and pre-warning an equipment failure through building an equipment failure pre-warning model. According to the management method of the gas transmission and distribution equipment, the whole life cycle of the gas transmission and distribution equipment is analyzed, effective management and application of the gas transmission and distribution equipment are achieved, meanwhile, analysis is carried out by combining a safety limit value of the equipment according to real-time parameter information of the gas transmission and distribution equipment, a failure warning model of the gas transmission and distribution equipment is built, a warning project is determined, a failure cause is analyzed, the operation security of the gas transmission and distribution equipment is improved and the full life circle management method has a relatively wide application prospect.
