Prefabricated polyurethane insulating pipes with galvanized iron and aluminium sheets
Galvanized iron sheet and aluminium sheet overhead polyurethane prefabricated insulating pipes are mainly suitable for the transportation of hot water, steam, cold water and other media. The temperature range of the media is from 20 below zero to 150 above zero.
1. Thermal insulation performance
The product adopts polyurethane insulation layer structure, which effectively reduces heat loss.
2. Convenient construction
The exposed length of the two ends of the insulation pipe is 150 MM-200 mm, which is convenient for butting and welding in site construction.
The finished insulating tile or foam can be used for the on-site insulation patch.
Pipe insulation is prefabricated by factory.
3. Weatherability
The galvanized anticorrosive coating is used to make the iron sheet for the outer protective pipe, which can be used in the open air environment for a long time without corrosion.
Because galvanized iron sheet and aluminium sheet are used instead of traditional PE outer protective pipe, the problem of long-term aging of PE in open air environment is avoided.
Spiral forming structure is adopted for galvanized iron and aluminium sheet outer protective pipe. The overall bending resistance and stress at joint of the structure are good.
4. Service life
Because the thermal insulation pipe of this structure is three-layer structure, the working pipe and thermal insulation layer are completely protected by the outer protective pipe, while the outer protective pipe adopts galvanized anticorrosive coating, which can be used continuously for 30 years under normal working conditions.
