Aluminum Cladding For Outside Pipes

2025-07-24

Aluminum cladding for outside pipe insulation are an efficient and durable protective material. Their core function is to protect the internal insulation layer from external environmental erosion while improving the aesthetics and stability of the overall system. Aluminum has good thermal conductivity, but when processed into a multilayer structure or used in combination with other materials, it can effectively reduce heat transfer, thereby achieving the purpose of insulation.

- Alloy type and applicable scenarios

1060 pure aluminum coil: purity ≥ 99.6%, with excellent corrosion resistance and plasticity, suitable for ordinary industrial pipelines and building pipeline insulation, low cost and convenient processing.

3003 rust-proof aluminum coil: contains 1.0%-1.5% manganese, corrosion resistance is significantly better than pure aluminum, often used in chemical, petroleum and other medium-corrosive environments, tensile strength 140-180MPa, suitable for complex molding processes.

5052 corrosion-resistant aluminum coil: Al-Mg alloy, with outstanding salt spray and acid-base resistance, good weldability, suitable for ships, marine engineering and high humidity environments.

- Thickness selection basis

Thin tube (DN≤100): 0.3-0.5mm is recommended, taking into account both lightweight and anti-deformation ability.

Medium-thick tube (DN100-300): 0.5-0.7mm, balancing rigidity and cost.

Thick tube (DN≥300): 0.7-1.0mm, enhancing impact resistance and long-term durability.

- Width:

The width of the aluminum cladding for pipe insulation can be customized according to the diameter of the pipe and the requirements of the insulation material.

- Surface treatment:

There can be different surface treatments such as glossy, matte or coating to improve its appearance and performance.

- Special protection:

Aluminum coil with polysurlyn moisture barrier can be used in highly corrosive environments. Its three-layer structure (barrier layer + water-absorbing layer + film layer) can effectively block water vapor and is suitable for pipelines in refineries and chemical plants.

Performance advantages: Why choose aluminum coils as the pipe insulation material?

- Long corrosion resistance life

A dense oxide film is naturally formed on the surface of aluminum, which isolates water vapor and chemical erosion. It can be guaranteed to be rust-free for 20 years in natural environment, which is much longer than iron sheet (3-5 years of rust).

- Lightweight and cost saving

The density is only 2.71 g/cm³ (iron is 7.85 g/cm³), and the weight per unit area is reduced by more than 60%, which greatly reduces the support load and logistics costs.

- Convenient and beautiful construction

Good ductility, easy to bend and wrap; the silver-white metallic luster enhances the uniformity of the project appearance.

- Environmental protection and economy

The recycling value of scrap aluminum can reach more than 50% of the price of new aluminum, with strong value preservation; the energy consumption of the production process is lower than that of steel.

Industry application scenarios of aluminum cladding for outdoor pipe insulation:

- Electricity/heat: power plant desulfurization flue, nuclear power pipeline, municipal heating pipeline network (3003 series is recommended).

- Chemical/petrochemical: chemical plant reaction pipeline, oil field oil pipeline (5052 series acid corrosion resistance is optional).

- Building/Environmental Protection: Roof insulation layer, chimney outer sheathing (1060 series is preferred for cost performance).

Our products have passed:

- EU CE certification (in compliance with EN 13501 fire protection standard for building materials), US ASTM B209 aluminum and aluminum alloy strip standard, Japanese JIS H4000 standard;

- Environmental certification: SGS test report shows that the heavy metal content (lead, cadmium, etc.) is far below the EU RoHS 2.0 limit, and can directly enter markets with strict environmental protection requirements such as the EU and North America.
