Zusammenfassung:	The invention discloses a method for evaluating the service state of an in-service small-caliber pipeline inner coating, and belongs to the field of oil and gas pipeline detection and evaluation. The evaluation method comprises the following steps: analyzing factors influencing the quality of the inner coating of the pipeline, establishing an inner coating service state evaluation index of the small-caliber pipeline, and obtaining an inner coating service state evaluation factor set U; based on the inner coating service state evaluation factor set U, the analytic hierarchy process is adopted to determine the weight of the evaluation index, and the weight vector W of the evaluation factor is obtained; establishing an inner coating service state comment set V; obtaining data of evaluation indexes; based on the data of the evaluation indexes and the inner coating service state comment set V, an evaluation table is established, and evaluation is carried out; and obtaining an overall evaluation relation B of the s
