insulation thickness

@ April 24, 2013 8:07 AM in How thick should steam pipe insulation be

Just from experience I've been working with 120lb steam for 13 years and 4" pipe down even on 1" pipe 1 inch of insulation isn't enough.  I put 3 inch on my 4 inch pipe and it's still warm to the touch.  Spirax Sarco guys say to put as thick as possible especially if your pushing the system for every BTU.  If it's a new install I really like the mineral wool type 2 inch shields about what 3 inch fiberglass does.  Just sayin.
