CELLULAR PLASTICS FOR CRYOGENIC INSULATION

Cosmodyne Corp. will use 250,000 lb of urethane foam to insulate the $7 million LNG ship-loading system in Brunei. The system involves 6.2 mi of stainless steel pipe, factory-preinsulated with Isonate CPR 285-2.5, a fire-retardant, fluorocarbon-blown rigid-urethane spray system formulated by CPR Div. of the Upjohn Co. The stainless steel pipe is mounted on a mandrel, sprayed with a release agent so that the foam will not adhere to the metal, rotated while spray equipment moves along a track to apply the first 2 in. of foam, wrapped with glass fiber reinforced tape, sprayed a second time with a 2 in. layer of foam followed by wrapping with glass tape, and then sprayed with a third layer of foam followed by wrapping with a glass reinforced epoxy vapor barrier to waterproof the surface which is finished by painting. Tests of the insulation during fabrication showed a nominal heat leak K-factor of less than 0.14 at -260 F and 0.14 at ambient temperature.
