Abstract
A pipeline comprising an outer steel pipe and an internal corrosion resistant covering adhesively joined to the inside of the steel pipe. The pipeline can be taken up onto a drum and later unwound and laid out without any observed deformation of the metal covering. A method for the manufacturing of the pipeline comprises the steps of applying an adhesive onto the outside of the metal covering and optionally also onto the inside of the steel pipe, inserting the metal covering into the pipe and expanding the covering until being in a good contact with the inside of the steel pipe, and curing the adhesive to make the metal covering adhere tightly to the inside of the steel pipe.
