Replace Steam Radiator Piping during reno?

I'm undergoing a gut kitchen renovation and wondering if there's any benefit to running new piping to radiators (one pipe steam) while all the walls are open? I won't (easily) get this chance again.

I've not noticed any particular issues, outside of a single radiator that doesn't get very for but is likely because 1. A large section is uninsulated in basement (fix underway) and 2. it's at the end of a main which has no main vent.

    Don't bother. Steam piping does develop leaks now and then, but it's rare.

    And do insulate and add a main vent!

    While you have everything open take a look at any horizontal steam pipes that run in the first floor ceiling to make sure they have some pitch. Over the decades houses sag and pipes can lose their pitch.

    I wouldnt touch them unless there was something obviously wrong. So long water isnt sitting in a pipe because of sagging, the pipe should last forever.

    I agree with all of the above posts.

    Check hangers and pitch. Maybe this is the time to install new radiator valve, and check for any obvious signs of leakage. If ok let it fly!
