Application Data of Polyurethane Thermal Insulation Pipe What is the Data of Thermal Insulation Layer of Polyurethane Thermal Insulation Pipe

Polyurethane insulation tube application information polyurethane insulation tube insulation layer information is what polyurethane insulation pipe insulation material data for density 60kg/m3 to 80kg/m3 rigid polyurethane foam, fully filled the gap between steel pipe and casing, and has certain bonding strength, make the steel tube, outer tube and insulation layer between the three constitute a solid whole.

The polyurethane directly buried insulation tube foam has good mechanical function and adiabatic function. Under normal conditions, it can withstand temperature 120 degrees, or be able to withstand temperature of 180 degrees when modified or combined with other insulation materials.

1. Anti-corrosive coating: Maintain external steel pipe to prevent corrosion of steel pipe and extend service life of steel pipe.

2. External protection steel pipe: Maintain insulation layer from groundwater corrosion, support task pipe and accept certain internal load, ensure the normal task of task pipe.

3. polyurethane foam layer: ensure the medium temperature, ensure the external tube surface to adhere to normal temperature.

4. barrier, reflective layer: ensure that inorganic foam data do not enter the inorganic hard and low temperature resistant layer; reflect the local heat of low temperature resistance.

5. inorganic hard insulation layer: low temperature resistance, ensure the interface temperature between inorganic insulation layer and ensure that the foam is not carbonized.

6. Drag Reduction Layer: Guarantee the free movement of the task steel tube during thermal expansion and contraction.

7. Task Steel Pipe: Ensure the normal activities of the delivery medium.
