Insulation spec for steam/condensate piping
Insulation spec for steam/condensate piping
(OP)
I'm finishing up a scope for some insulation contractor proposals and I was wondering what is standard for insulation thickness and type. We're insulating piping for steam, boiler blow down water, and condensate with diameters ranging from 3/4" to 6". I was planning on spec'ing fiberglass, 3 lb density, with 2" thickness for 6" pipe and 1 1/2" thickness for smaller diameters. Any thoughts?
Thanks in advance

Let me know if you want me to take a look at them. Fiberglass is good if it won't have any traffic on it (eg Operators walking on the piping). If you need something more robust than calcium silicate is often specified but it's insulation value is not as good and it's more time consuming to install.

- safety... to protect workers who might accidentally contact the steam pipes
- Energy efficiency to reduce heat loss to an acceptable standard
- temperature control - where it is important to reduce heat loss to an absolute minimum or to prevent rapid temperature transients caused by heat loss
So anything from basic lagging to molded calcium silicate could be called for... and the more efficient the lagging, the more expensive.JMW
