Steel grade according to e215 standard.
The sizes of pipes are specified: diameter, length, wall thickness.
The deviation from the alignment is the deviation of the location of one surface relative to another surface.
To influence the surface of the hole, it is important to know the wall thickness. If it is too small, the processing is possible only by thin turning with fixing on the ends. With a certain thickness, you can try fine grinding, but much will depend on the skill of the grinder. It is better to pay attention to the seal, for which 0.2 mm is not a problem.
