High-temperature flange
Thread Content
For high-temperature flanges, those operating at temperatures above 250 degrees, I would like to ask an expert: is it necessary to use insulation?
It depends on the specific situation in which it will be used; this is just my personal opinion for reference only!
Insulation should be added to reduce heat loss
It’s already above 250 degrees, so insulation is definitely necessary.
Personal opinions should take into account pipelines or equipment connected to flanges; if such equipment or pipelines are insulated, then insulation should be applied. Of course, if the flange needs to be opened and closed frequently, another insulation option should be considered.
Without a doubt, insulation is necessary.
In addition to considering heat loss, it is also necessary to take into account issues related to the detection of leaks and the thermal strength of bolts. Section 5.2.3 of the \"Design Code for Insulation of Industrial Equipment and Piping\" GB50264-97 specifies requirements for insulating valves and flanges used with flammable, explosive, toxic, and other hazardous materials
