Elevated Horizontal Tanks
Elevated Horizontal Tanks
(OP)
I had this question in the API forum and had no response--probably the wrong forum.
Horizontal A.S.T.'s, supported by structural steel frameworks, are 10' above ground level. These tanks contain diesel fuel and kerosene and are in a diked area. Dike walls are 48" high.
Should the steel legs supporting these tanks be protected from fire with fire resistant material in order to comply with NFPA combustible and flammable liquid code?
If "yes" what type of material is acceptable and yet be resistant to the elements--rain,snow and ice.?

This location is somewhat isolated and is typical of rural installations prevelant in past decades.

To protect steel structural elements from an external hydrocarbon pool fire, your selected assemblies should comply with ASTM E 1529. In the US, Carboline makes some off the shelf assemblies, but they are not inexpensive. Second, and as important, is that the column weight/ft. must support the dead load of the insulating material.

IFR, are you suggesting that the steel legs be replaced with reinforced concrete or pedestal?

Your talking about an intumescent material. I am not aware of such a product for protecting a steel structure from a hydrocarbon pool fire.
