POLYURETHANE FOAM AND INSULATION LAYERS

The removal of insulation layers using the dry ice method is an additional innovative application in industrial use.

Insulated pipelines and tanks in nuclear power plants, cogeneration plants, chemical plants and refineries are regularly checked for leakages and in terms of their functionality. The complete removal of the insulation layer that is up to 800 mm thick is necessary to this end. But also smaller machinery and insulation can be removed with dry ice.

For the dry ice cleaning method, no complex preparation of the surface and the working space is needed is needed. Using the dry ice method, the insulating material (which is mainly polyurethane form) is removed from the surface without exception. A perfect surface is created for a corrosion protection coat of paint. Laborious manual work is done away with and the components can be immediately checked without any further reworking. The use of dry ice does not create any steel granulate burden in the vicinity of the industrial plant. Furthermore, the dry ice cleaning process is much faster than comparable cleaning operation. Dry ice does sublimate on contact which leads to the cleaning process having no residues other than the dirt itself. The temperature of dry ice (minus 78 degrees) ensures that the residues become brittle, and thus also the hardest impurities are removed. Furthermore, does the sublimation process clean any spring valves in the mould.
