As a marine aluminum profiles manufacturer, we have cultivated the overseas market for many years, serving shipyards in Europe, America, Japan, and South Korea. Through long-term export practice, we have found that the reason marine aluminum pipe have become the core tubing choice in modern shipbuilding is no accident. It is due to the high degree of compatibility between their core technological characteristics and the harsh operating environment of ships, and is also an inevitable result of the trend towards lightweight and energy-efficient shipbuilding.

Corrosion resistance, adapting to the harsh marine environment, is the core prerequisite for aluminum pipes' success in marine applications. In the marine environment, salt spray, tidal immersion, and chloride ion corrosion can cause severe damage to tubing. Traditional steel pipes are prone to corrosion and have high maintenance costs, while the natural corrosion resistance of aluminum pipes becomes prominent. Our marine aluminum pipe is made from specialized marine-grade aluminum alloys such as 5083 and 6061. A dense oxide film naturally forms on its surface, resisting long-term seawater corrosion. After anodizing, it withstands over 1000 hours of salt spray testing, with an annual corrosion rate of less than 0.03mm and a service life of over 30 years. Aluminum tubing for yacht cooling systems exported to a US shipyard, suitable for its near-shore leisure yachts, has undergone five years of operation and maintenance testing in high-salinity seawater without significant corrosion or leakage, significantly reducing maintenance costs for the shipowner. This is a key reason why our products have gained recognition from overseas customers.

The combination of lightweight and high strength, meeting the energy-saving and safety requirements of ships, is the core driving force behind aluminum tubing's replacement of traditional tubing. A ship's weight directly affects speed, fuel consumption, and navigation stability. Aluminum's density is only one-third that of steel, and our marine aluminum pipe, through precision extrusion and tempering, achieves a tensile strength of over 300MPa, fully meeting the pressure requirements of marine piping systems. Taking an ocean-going cargo ship exported to a French shipyard as an example, its hydraulic control system and seawater cooling system both utilize our 6061-T6 aluminum pipe. Compared to traditional steel tubing, the weight of the tubing per ship is reduced by more than 60%, resulting in a cumulative weight reduction of nearly 20 tons for the vessel. Actual navigation verification has shown a 12% reduction in fuel consumption, aligning with the international trend of low-carbon emission reduction in shipping while also enhancing the ship's navigation flexibility and stability.

Excellent processing and adaptability allow it to accommodate complex piping layouts on ships, reducing construction costs for overseas shipyards. The compact and complex piping layouts of ships place extremely high demands on the bending, welding, and forming performance of the tubing. Aluminum pipe possesses excellent weldability and ductility. Utilizing dual-pulse MIG welding technology, precise welding can be achieved, resulting in a narrow heat-affected zone and a joint strength coefficient exceeding 0.9. Furthermore, it can be processed into round and square tubing of various specifications according to ship design requirements, adapting to various scenarios such as seawater cooling, fuel transportation, and ventilation. We customized specialized aluminum tubing for a UK-based hovercraft manufacturer, precisely matching the compact layout of their hull. This allowed for direct installation without complex processing or adjustments, significantly shortening the shipyard's construction cycle and reducing construction difficulty.

Based on years of export experience, I deeply understand that the widespread adoption of aluminum pipe in marine applications reflects the synergistic development of materials technology and the maritime industry. Currently, the international shipbuilding industry is increasingly demanding low-carbon, high-efficiency, and long-lasting performance, extending the application scenarios of marine aluminum pipe from ordinary piping systems to specialized fields such as polar vessels and high-end yachts. As an exporter, we are always guided by overseas market demands, optimizing alloy formulations and production processes, overcoming corrosion challenges in the high-pressure environment of the deep sea, and continuously providing overseas shipyards with cost-effective marine aluminum pipe solutions.

Aluminum pipe, with its core technological advantages of corrosion resistance, lightweight, and ease of processing, perfectly meets the stringent operational requirements of ships and aligns with the international trend of low-carbon development in shipping. In the future, with the intelligent and green development of ships, we will continue to deepen our technological research and development, promoting the upgrading of marine aluminum tubing towards functional integration, and contributing to the high-quality development of the global maritime industry.
