Insulated coke drum, insulation system therefore, and method of installing same

An insulated coke drum comprising:

• (a) a coke drum having an external diameter, an exterior surface, and a longitudinal axis;
• and
• (b) an insulation system installed on the coke drum exterior surface, the insulation system comprising:
• i) an insulation support system comprising a plurality of vertically spaced insulation support rings supported by a plurality of laterally spaced apart brackets, each bracket in turn secured to and supported by one of a plurality of vertical steel bands, the steel bands supported near the top of the coke drum by a collar;
• ii) a plurality of insulation panels secured to the support rings, each insulation panel comprising insulation material and an exterior metal jacket, each insulation panel positioned between horizontally adjacent insulation panels with single-folded standing seams;
• and
• iii) a plurality of external tensioned insulation securing cables corresponding in number to the plurality of support rings, each of the cables routed through respective horizontally aligned eyelets in each single-folded standing seam external of the insulation panels.

An insulation system or kit comprising:

• i) an insulation support system comprising a series of weldments adapted to be welded to an exterior surface of a vessel in spaced apart horizontal rows, and a plurality of insulation support rings adapted to be vertically spaced and supported by but not attached to the weldments, each support ring having a diameter greater than the external diameter of the vessel to be insulated;
• ii) a plurality of insulation panels adapted to be secured to the support rings, each insulation panel comprising insulation material and an exterior metal jacket, each insulation panel positioned between horizontally adjacent insulation panels with single-folded standing seams;
• and
• iii) a plurality of tensionable insulation securing cables corresponding in number to the plurality of support rings, each of the cables adapted to be routed through respective horizontally aligned eyelets in each single-folded standing seam external of the insulation panels.
