Insulation issue of the inner head in the skirt of insulation equipment
Thread Content
Seeking expert advice: For towers or vertical tanks with a skirt, is it necessary to insulate the head inside the skirt? Are there any specifications for the specific requirements? Thank you very much. .
Are there any specific requirements or standards that can be found? Thank you
Could you please find the specific specifications?
Skirt protection layer: When there are flammable or explosive substances inside the tower or in the containers surrounding it, a fire could cause the skirt-type supports to lose their strength due to rising temperatures; therefore, a fire-resistant layer should be provided for the skirt. When the skirt base D ≤ 1500 mm, a fireproof layer is applied only on the outside ； When the skirt base D > 1500 mm, a 50 mm layer of asbestos cement is applied on both sides. When the operating temperature inside the tower is very high, the temperature difference between the tower and the skirt causes uneven thermal expansion, which can worsen the stress conditions on the welds connecting the skirt to the bottom head of the tower; in such cases, it is necessary to insulate the skirt.
Thank you for your reply, but what I would like to ask is the basis and standards for insulation of the inner head in the skirt.
SH/T3098-2011 contains provisions regarding the insulated type of bottomed heads.
Learn* knowledge. But our factory doesn’t have insulation; it depends on the needs.

Hello, is there significant heat loss without insulation? Should insulation be used in accordance with the standards?
