Abstract

A method for coating a pipe (1) in the interior thereof, wherein the method has at least the following method steps: (i.) providing an immersion basin (2) which is filled with a coating liquid (3); (ii.) first immersion of the pipe (1) to be coated into the coating liquid (3); (iii.) first removal of the pipe (1) to be coated from the coating liquid (3) ensuring an angle (α) between the central axis (M) and the surface of the coating liquid (3) with 1°<(α)<30°; (iv.) second immersion of the pipe (1) to be coated into the coating liquid (3); (v.) second removal of the pipe (1) to be coated from the coating liquid (3) ensuring an angle (β) between the central axis (M) and the surface of the coating liquid (3) where −30°<(β)<−1°.
