Aluminum alloy pipes fitting for ship
Aluminum alloy has both the excellent properties of aluminum and steel, and mainly has the characteristics of light weight, high strength and easy processing. In addition, aluminum alloy has no magnetism and good welding performance, which also lays the foundation for its wide application. At the same time, aluminum ore is widely distributed, rich in content and abundant in resources. The application value of aluminum alloy in low temperature and corrosive environment is relatively high, because it is not brittle at low temperature, and as the temperature decreases, the shape and strength of aluminum alloy pipes fitting will continue to increase, especially the increase in toughness and elongation. , Provide compressive performance for aluminum alloy tube, so that it can work normally at extremely low temperature without being damaged.
With the continuous development of new technologies for aluminum alloy pipe materials, aluminum alloy pipes have been greatly applied in the shipbuilding industry due to their excellent properties. As an alloy material, aluminum alloy tube has many characteristics such as light weight, high strength, easy processing, and corrosion resistance and low temperature resistance. It is suitable for making various parts of ships.
In the current shipping industry, it is important to consider the strength and corrosion resistance of ship materials. Combining these requirements and selecting appropriate materials can improve the applicability of ship materials. In the field of ship manufacturing, there are high requirements for equipment strength and corrosion resistance, which are divided according to the actual use. In the upper part of the hull, duralumin alloy will be 6000 aluminum alloy, mainly aluminum alloy with strong corrosion resistance . 7000 aluminum alloy can also be applied to some structures on the ship
Application of aluminum alloy pipe in ship
The vigorous development of the shipbuilding industry has made many developed countries begin to dig deeper in the shipbuilding industry-related fields, and the development trend of aluminum alloys for ships has also shown diversification.
Currently,The development of aluminum alloys for ships in developed countries in Europe and America is mainly manifested in the following three categories:
1) One type of structure. The first type of structure mainly refers to large-strength structural parts, such as the hull of a large ship, missile launching tube, etc. The typical representative of this type of 4 is the launch orbit of the "Ford Ship". The launch orbit of this American aircraft carrier is an aluminum alloy structure.
2) Second-class structure. Compared with the first type of structure, the structure of the second type of structure is less stressed, that is, the medium part structure in the ship, such as windshield, doors and windows, water tanks, etc., this type of structure usually bears less force, and most of the materials used are It is an alloy material, and it is also a widely used material structure in shipbuilding.
3) Three types of structures. The three types of structures are different from the force standards of the first and second types of structures. The three types of structures mainly emphasize the versatility of materials. The same materials have multiple uses, which is the main difference between the three types of structures. The decorative materials inside the cabin can not only embellish the environment in the cabin, but also have the effect of physical heat insulation and sound insulation, and its corrosion resistance is extremely strong. For example, foam aluminum panels can be used as doors and windows, as well as interior decoration, and can also be used for engine sound insulation, which is extremely practical.
Aluminum and aluminum alloy tubes are more common in shipbuilding. With the development of ship technology, these three types of structures will surely achieve new breakthroughs and innovations in the field of shipbuilding, making full use of their durability and durability characteristics, and better Enrich ship performance
