Fireproofing on supports only
Fireproofing on supports only
(OP)
Dear All
I wonder why in many engineering specs there is fireproofing on supports and not on the vessel walls. For examples it happens a lot that the skirt has a 50 mm concrete fireproof and there is no fireproof on the vessel wall at all. Any explanations?
Warm Regards

Some Horton Spheres (used for LPG / Propylene storage) do have fire-proofing everywhere. Just because of safety issues, though.

That is in addition to NBrink's comment that the bottom part of the vessel typically have liquids which can absorb the heat.

I have seen vessels offshore fully fireproofed and not just the supports. These were fireproofed with Chartek and it was applied due to the possibility of a jet fire impinging on the vessels. Typically offshore vessels can be blowndown (remove the gas inventory) in say 15 mins. The Chartek is there to protect the vessel whilst blowndown takes place. Onshore I have only typically seen tall vertical vessels (columns) with their skirts fireproofed on the outside - sometimes on the inside dependent on vessel size and CLient requirements.
