Technical performance
Thermal foam insulation dedicated to pre-insulated pipe systems consists of closed-cell foam. This foam insulation can be used as a single or multi-layer according to the requirements of the operation.
Performance
Decisive for the number of layers is the operating temperature (range -200°C to +120°C), fire resistance/use inside hazardous areas and mechanical influences on the pipe.
Insulation
The effectiveness of the thermal foam insulation is important and is related to the density of the foam material. An increased insulation foam density creates a strong connection between insulation material, medium pipe and outer jacket. At the same time a higher density increases the thermal conductivity and thus a higher heat loss to the environment. A lower density level leads to a decreased impact resistance but reduces heat loss.
adapation
This demonstrates that the construction of a pre-insulated pipe is a kind of successful adaption between all the factors involved. The modularity of the product allows an easy adjustment following the requirements of ambient and operating conditions. The outer jacket is manufactured as a spiral-wrap pipe made of metallic sheets with an inside fold to create a smooth surface - moisture and dust tight.
