FIELD: transport machine building.
SUBSTANCE: invention relates to pipeline or pipe structure for use in oil or gas medium. Pipeline is equipped with radio frequency identification (RFID) mark for identification of said pipeline. Pipeline has an external surface and comprises a first end part for connection to the second pipeline, a second end part and a middle part between the said end parts. Said RFID tag is located in the elongated recess made in the pipeline. Said recess is made in outer surface (S) and extends in tangential direction or axial direction (DT), wherein said recess is elongated in a direction parallel to surface (S) in which it is made.
EFFECT: technical result is protection of mark and increased strength of pipeline.
