Do trade routes affect Orbital Refinery Range?

 I doubt it. They both have infinate range, or at least very large range. If what your asking is do the refinery ships follow the trade routes, then I don't know, but I would assume that they have their own routes.

AFAIK trade ports generate income per se,but the the best tactic is to deploy them in adjacet grav wells so they create a trade route, the longer the trade route the higher the raw income.

For refineries i have noted that they affect extractors in the adjacent energy wells, not sure if their radius is bigger, i need to play more to burn my hand with this thought

Trade ports send their ship to any other trade port you have constructed, as well as the ports of emipres which you have a Trade Alliance with.

Refineries, however, only send their ships to extractors within the well the extractor is in and owned extractors 1 jump away.

Refinery ship only go 1 jump away? I thought they had routes, but then again I never followed them that long. Well this is good, it means that they go to extractors around gas giants and stuff 1 jump away i'm assuming.
