A resin line is provided with a corrugated pipe that has a wall with individual circumferentially arranged through openings. Sections of the wall are circumferentially closed. The wall has a cross-sectional shape of non-rotational symmetry transverse to a longitudinal center axis and is divided in relation to the cross-sectional shape of non-rotational symmetry into a first part and a second part. The first part has a flattened base extending in a transverse direction transverse to the longitudinal center axis across a length of the corrugated pipe. The second part has an arc shape extending in a direction of height transverse to the longitudinal center axis across the length of the corrugated pipe. The flattened base has a width measured in the transverse direction that is larger than a height of the arc shape measured in the direction of height.
