Regarding the insulation issue of medium-pressure steam drums
Thread Content
Is it necessary to insulate the manual valve at the bottom of the drum safety valve? Without insulation, there is a risk that heavy rain will cause thermal shock to the valves
That has little impact; generally, insulation on the inlet and outlet of reactors is not recommended, so there’s no need to be that strict.
Insulation prevents heat loss and helps to retain warmth
It can be insured or not. . That amount of heat loss is also very small. .
