Aluminum External Pipe Insulation Jacket

2025-09-10

Aluminum external pipe insulation jacket is a high quality material used for insulation and heat preservation of exterior pipes, widely used in industries such as petroleum, chemical and power generation. Its primary function is to improve the thermal efficiency of pipes, reduce energy loss, and protect them from environmental influences.

Material Selection Guide
- Pure Aluminum Series (1060/1100)
Features: Aluminum content ≥99.6%, strong corrosion resistance, and low cost.
Applicable Applications: General industrial pipes, civil building insulation and environments with high rust prevention requirements.
- Alloy Series (3003/5052)
Features: The addition of elements such as manganese and magnesium increases strength by over 30% and provides enhanced rust prevention.
Applicable Applications: Chemical pipelines, coastal areas, or humid environments requiring long-term corrosion resistance.
- Recommended Thickness
Conventional thickness: 0.3mm-0.8mm, balancing cost and strength.
Special Requirements: For high-pressure pipes or areas with high risk of mechanical damage, a thickness of ≥1.0mm is recommended.

Core advantages of aluminum external pipe insulation jacket:

- Weatherproof and Corrosion-Resistant
Aluminum pipe insulation jacket naturally forms a dense oxide film on its surface, protecting it from rain, acid, alkali, and UV rays. It is particularly suitable for highly corrosive environments such as chemical and coastal environments. For example, under comparable corrosive conditions, aluminum jacketing far outlast galvanized iron sheets, reducing the cost of frequent replacement.

- Long-Lasting Thermal Insulation and Energy Saving
As the outer sheath of pipes, aluminum jacket rolls, when used in conjunction with insulation materials such as rock wool and glass wool, form a closed, insulated structure, effectively reducing heat loss. Its low thermal conductivity (approximately 0.03 W/m·K) reduces energy consumption and complies with green building standards.

- Lightweight and Easy Installation
With a density of only 2.71 g/cm³, aluminum jacket rolls are lightweight and flexible, allowing them to be bent and wrapped around pipes to accommodate various shapes and sizes. No special equipment is required for installation, significantly shortening construction time and reducing labor costs.

- Aesthetics and Decorative Features
The aluminum jacket' smooth surface and silvery-white metallic luster enhance the overall aesthetics of the pipe. Surface treatments such as spraying and lamination are supported, allowing for custom colors and textures to meet architectural decorative needs.

- Environmental Protection and Value Preservation
Aluminum jacketing rolls are 100% recyclable, with the recycling value of scrap aluminum coils exceeding 50% of the price of new material. This aligns with the concept of a circular economy and reduces resource waste.

Applications of aluminum exterior pipe insulation jacket:

- Industrial Sector
Petrochemical Industry: Pipelines transporting high-temperature steam or corrosive media are insulated with 3003 alloy aluminum coils and rock wool, achieving a lifespan of over 15 years.
Power Industry: Aluminum coil wrapping of heating pipes reduces heat loss and improves power generation efficiency.

- Civil Construction
Central Air Conditioning Systems: Aluminum coil wrapping of chilled water pipes prevents condensate corrosion while enhancing aesthetics.
Heating Pipes: Aluminum coil wrapping of floor heating pipes in northern China extends service life and reduces maintenance costs.

- Municipal Engineering
Urban Heating Networks: Aluminum coil wrapping of direct-buried pipes with polyurethane foam reduces heat loss and meets energy conservation and emission reduction requirements.
Transportation: Aluminum coil wrapping of piping systems in subway stations, airports, and other locations enhances overall safety and aesthetics.

Aluminum external pipe insulation jacket is an important material to ensure the efficient operation of the pipeline system. It can significantly improve the insulation effect of the pipeline, reduce energy consumption, and extend the service life of the pipeline.
