A measuring tube for a flowmeter and a process for making the measuring tube. The measuring tube is lined with a tubular lining of thermoplastic material, particularly PTFE or PFA, which comes into contact with the measured substance which flows through the tube. The ends of the tubular lining are flanged around end flanges of the measuring tube after the ends of the tubular lining have been plasticised by heating. The plasticised ends of the tubular lining are turned outward by more than 90 DEG and then forced into undercuts in the end faces of the end flanges. Upon cooling, the ends of the lining are in intimate contact with the end faces of the end flanges and the undercuts in the end faces.
