In 2014, to meet growing demand for energy exports and modernize its infrastructure, the United Arab Emirates (UAE) launched a major onshore crude oil pipeline project. The project aimed to build a new pipeline system spanning hundreds of kilometers, requiring efficient and safe transportation of crude oil and resilience to the long-term challenges posed by the Middle East’s extreme environmental conditions. A fundamental and critical material—1060 aluminum coils—played an indispensable role in this project. A total of 2,000 tons of material were purchased for external corrosion protection and pipeline insulation.

Project Background and Key Requirements
Located on the Arabian Peninsula, the UAE is exposed to intense sunlight, extremely high ambient temperatures, and, in some areas, corrosive dust and salt fog. The long-term reliability and safety of the pipeline, which is the country’s energy artery, are of paramount importance. The project’s key objectives included:

Highly effective insulation: Crude oil transported through the pipeline must maintain a specific temperature to ensure its fluidity, while high external temperatures exacerbate evaporation and crude oil loss, creating a thermal risk to the surrounding ecosystem. Therefore, the pipeline system requires a high-quality insulation layer.

Long-term corrosion resistance: The external metal components of the pipelines are exposed to harsh environmental conditions and must have extremely high corrosion resistance to ensure the long-term safety of the structure and reduce maintenance costs.

Ease and cost-effectiveness of construction: Large-scale projects with tight deadlines require the use of protective materials that are easy to handle and install, as well as adaptable to the requirements of large-scale industrial construction.

Solution: Grade 1060 aluminum coil was selected as the protective outer casing.
After a comprehensive design evaluation, grade 1060 aluminum coil was ultimately selected as the material for the outer protective casing for the pipeline’s anti-corrosion and thermal insulation layer. This choice was based on the following superior properties of grade 1060 aluminum coil:

Excellent corrosion resistance: As an industrially pure aluminum with an aluminum content of over 99.6%, grade 1060 aluminum naturally forms a dense and durable protective aluminum oxide film on its surface. This film effectively resists atmospheric exposure, ultraviolet radiation, sand, and salt fog, providing a reliable barrier for expensive internal insulation layers (such as mineral wool or glass wool) and the pipeline body, ensuring an estimated service life of decades.

Excellent moisture resistance and sealing: Professional rolling and edge sealing ensure that aluminum coils form a continuous, hermetic protective layer. This is crucial for preventing nighttime condensation or rare rainwater penetration into the insulation layer, ensuring long-term dryness and high insulation performance, as well as preventing insulation degradation and internal corrosion caused by moisture absorption.

Excellent reflective and thermally conductive properties: The smooth surface of 1060 aluminum has a high solar reflectivity (over 80%). It reflects most of the sun’s heat back, reducing heat transfer from the external environment to the pipeline’s interior. This synergistically interacts with the inner insulation layer, ensuring a stable crude oil temperature inside the pipeline and reducing cooling energy consumption.

High processing and installation rates: 2,000 tons of 1060 aluminum coils are processed into coils of specified width and thickness for easy transportation and on-site forming. Moderate strength and excellent flexibility allow aluminum to be easily bent, wrapped, and secured in place using specialized equipment, significantly improving construction efficiency and meeting the rapid completion requirements of large-scale pipeline projects.

Project Results and Far-Reaching Impact

During the project’s implementation in 2014, these 2,000 tons of 1060 aluminum coils were successfully used in the corrosion protection and insulation system of the entire oil pipeline. They served as a strong, shiny “armor” for the pipeline, effectively withstanding the harsh conditions of the UAE.

This project not only completed construction on time and to high quality, increasing the UAE’s export potential, but also became a model example of the large-scale, standardized use of 1060 aluminum coils in large-scale energy infrastructure. It demonstrated that even in traditional sectors such as the oil industry,
