Shouldn't 2" insulation be used on steam drop headers. State Supply only sells 1".

Pipe Insulation Source
What are some good sources for pipe insulation?

Depends on where you are located
I use Homan's Associates here in MA. Yellow pages of course, but also your national companies (Certain-Teed, Knauf, Owens Corning, Armacell, et. al) should have distributors listed on their web sites.0 -

Generally
most model energy codes require (or recommend if "guidelines") 2-inch insulation for steam piping over 1.5 inch IPS.
If you cannot get that thickness you may have to "nest" the insulation. There are tables to do this, starting with the bare pipe size, adding the first layer and selecting the second layer based on the OD of the first layer. Not always perfect so get a single layer of 2-inch thickness if you can.
For practical purposes though, that first inch cuts the heat loss to about 1/6th that of bare pipe. The second inch cuts that in half again. Go to four-inch thick and it cuts that smaller number in half again.
Heck four inch insulation on your piping? You would run out of room and have to move....0
