Pittsburgh Corning FOAMGLAS® Insulation Systems for Low Temperature Piping, Tanks, and Vessels
Service temperatures below ambient down to -50°C (-58°F)
A one layer system is sufficient for this temperature range. A double layer system should be applied when the recommended insulation thickness is thicker than the maximum available thickness. Shells and segments appropriate to the shape of the surface to be insulated should be applied with staggered joints and the joints filled with PITTSEAL® 444 or other suitable mastic.
Service temperatures from -50°C to -180°C (-58°F to -292°F)
A double layer system is generally sufficient for this temperature range. The insulation layers should be chosen in such a way that the interface temperature of the two layers is not lower than ‑50°C. Shells and segments appropriate to the shape of the surface to be insulated should be applied with staggered joints and the outer-layer joints filled with PITTSEAL® 444 or other suitable mastic.
Service temperatures below -180°C (-292°F)
At this temperature a three layer system should be used. For small pipe diameters a double layer system could be applied depending of weather or service conditions. Many designers and some national codes impose liquid oxygen compatibility requirements to all applications at temperatures below -180°C.
