Hello.
Could you tell me what are the criteria and standards to define use or not of thermal insulation on a pressure vessel (columns, drums, heat echangers).
Thanks.

Wrl69,

Your question is too vague.....

Are you asking about the minimum wall temperature where insulation is required for "personnel protection" ?

OSHA and ASTM have information about this topic.

Please restate your question....
