    Publication number: 20220062967
    Abstract: A method for producing a tube (101-104), the method comprising: providing a preform (1a-c, 70) in a mandrel (2), the preform (1a-1c, 70) having two ends; flow forming the preform (1a-c, 70) with a plurality of rollers (4-5,31-38) such that in one flow forming pass neither one of the two ends of the preform (1a-1c, 70) is flow formed, thereby producing the tube (101-104); and mechanically forming mechanical connection ends on the two ends of the tube (101-104). Also, a seamless tube (101-104), a pipeline comprising a plurality of seamless tubes (101-04), and a machine for flow forming a preform (1a-1c, 70) into a tube (101-104).
