Centrifugal glass wool tubes is especially used in every kind of pipes or tubes for thermal insurance(including refrigerating, hot water and steam pipes).It can work well in the environmental temperature range from -4℃～454℃at exposure or close status.

As this material get the characters of water-proof, anti-corrosion and mildewing-proof etc, which is good in stopping condensation and freezing of the pipes. It is widely used in building, heating power pipes, air condition and refrigerators for thermal insurance, increasing15-30% of energy conservation effect.

Facing like Alum. foil can be applied to the surface for preventing moisture and radiation protection.

FSK facing or other vapor barrier materials can be applied to outside surface of pipe cover.
