Small Aluminum Extrusions: Aluminum Pipe
In the field of shipbuilding, aluminum alloys have gradually become an important material to replace traditional steel due to their light weight, high strength, and corrosion resistance. In particular, small ships such as yachts, patrol boats, fishing boats, etc. have higher requirements for lightweight and seawater erosion resistance, and the application of aluminum alloys meets these needs.
Marine small aluminum extrusions can be divided into four categories according to their functions and forms:
Structural profiles
5052 aluminum-magnesium alloy: It is of low magnesium content, excellent formability and widely used in the hull side plates, decks and other structures of inland ships.
5083 aluminum-magnesium alloy: It has higher magnesium content, outstanding resistance to seawater corrosion and is the preferred material for key parts such as the bottom and stern of marine ships.
6061 aluminum alloy: It has balanced strength and toughness, which is commonly used in ship accessories such as masts, door and window frames.
Decorative profiles
They are mainly surface-treated aluminum profiles, such as anodized or painted profiles, which are used for cabin internal partitions, decorative panels, etc., taking into account both aesthetics and wear resistance.
Equipment support profiles
They need to have high rigidity and load-bearing capacity, such as pipe brackets, engine bases, etc., often made of 6082 or 5083 alloy.
Special functional profiles
This kind includes embossed aluminum plates (anti-slip decks), seamless aluminum tubes (high-pressure fluid delivery), etc., to meet the specific functional requirements of ships.
6082 aluminum pipe
6082 aluminum tube belongs to Al-Mg-Si alloy. Through the optimized ratio of silicon and magnesium elements and T6 heat treatment process, it has the following core advantages:
High strength: The yield strength can reach 275MPa, which is far higher than ordinary aluminum tubes (such as 6061), and is suitable for hull structures that bear dynamic loads.
Easy to process: Complex cross-sections (such as H-type and groove type) can be formed by extrusion, and modular assembly can be achieved through welding process to shorten the construction cycle.
Corrosion resistance: It is stable in freshwater and seawater environments, and can be further improved by anodizing or painting.
Applications of 6082 aluminum pipe
Hull structure reinforcement
Keel and bulkhead support: It replaces traditional steel, reduces hull weight while ensuring strength, and improves speed and fuel efficiency.
Detachable components: Standardized profiles facilitate the rapid installation and maintenance of prefabricated cabins and equipment brackets.
Fluid delivery system
Fuel and cooling pipes: Smooth inner wall reduces resistance and its corrosion resistance is better than steel pipes, and long-term maintenance costs are reduced.
Ballast tank pipes: It is adapt to the high-pressure environment of seawater and ensures the reliability of ship balance adjustment.
Mechanical and power systems
Engine brackets and drive shafts: It can withstand high-frequency vibration and impact, and meet the performance requirements of special ships such as high-speed boats.
Hydraulic system pipelines: High-precision aluminum tubes ensure the stability and safety of fluid control.
Special applications in marine engineering
Offshore platform support structure: It is resistant to seawater corrosion and high strength characteristics, extending the service life of facilities.
Deep-sea exploration equipment frame: Lightweight design takes into account pressure resistance and adapts to complex marine environments. Welcome to inquire aluminum pipe price.
