one pipe steam heat

Rrothowski

I am in the process of restoring back to 1926 my one pipe steam heating system. I'm installing the insulation back that was lost due to asbestos abatement through out the years. The hangers have been removed what is code? It's 25 feet of a horizontal 2 inch main. Thank you in advance, Richard Rothowski

What are you asking for.
Is it the code requirement for insulation or hanger spacing or both?

If it is hanger spacing. Eight to ten feet for two inch steel pipe.
As for the insulation. Fiberglass insulation. The greatest wall thickness that you can afford.

thanks, asking for hanger spacing didn't know there was an insulation code, sorry about the confusion

1 inch is plenty. Put all the insulation you can afford in your attic
