1. A method of coating a pipe (1) in its interior, wherein the pipe (1) to be coated in its interior has
an outside (a) and an inside (b), a first outer end (e1) at the first end of the pipe (1) and a second outer end (e2) at the second end of the pipe (1), a length (L), a first inside diameter (D1) at the first outer end of the pipe (1) and a second inside diameter (D2) at the second outer end of the pipe (1), and a central axis (M), wherein the method according to the disclosure is characterised in that the method has at least the following method steps: (i.) providing an immersion basin (2) which
is filled with a coating liquid (3) up to a filling level (h) andis suitable for receiving over its full length (L) the pipe (1) to be coated, (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) with −30°<(β)<−1°, and (vi.) ensuring a filling level of the coating liquid (3) in the immersion basin (2) with (h)>(L)·sin (α) and (h)>(L)·sin (β). |
