If you are intending to paint plastic pipes because they are visible in a room and you want to disguise them, the answer is yes.
For the white or cream coloured pipes, that carry water (hot and cold) from a source, you may need to give them a light sanding to remove the printing on the surface. Follow with a wipe with a tack cloth, then paint with a good latex primer and finish with your top coat. In some cases two or possibly three coats of your top coat will do if you have no primer.
For the large black pipes that carry waste water away, a light sanding, followed by a good latex primer and then your top coat will get the job done.
If you are painting the pipes hoping the paint will reduce condensation, or worse still a leak, I'm sorry, paint won't help you.

Yes one can paint plastic tubes associated to solar heating exchangers on the roof, usually that requires a ladder with a decent length enough to reach the roof, in the case of a tower block, access to the top parts of the tower. Plastic tubes benefit from application of a poly vinyl paint of the PVC type. Care to ensure that the plastic is not hostile to the solvent in the paint, such that the plastic dissolves. Normal paint such as household emulsion and oil gloss can also be used but due to the exposure of the pipes to environmental factors, you will probably find the paint peeling in due course with heat sand dust abrasions and rain. What is not a good idea, is to paint the solar panels or the heat exchangers on the roof. If the tubes are associated to the heat exchange process, in other words the pipes sit on the roof, and absorb sun, you would be best advised to choose a paint that absorbs heat, and does not reflect it, as that would make the system more effective than normal paints. But its much more fun, not to be bothered with matters on the roof, while you can get a good look at your woman in the swimming pool, don't you think?
