Grade LRA Shotblasted SA2.5 Shipbuilding Steel Plate

The following is an introduction to Grade LRA Shotblasted SA2.5 Shipbuilding Steel Plate:

 

 

Shipbuilding Steel Plate

 

Application scenarios: Steel plates specifically used for shipbuilding. In various parts of the ship, such as the hull shell, deck, bulkhead and other structures, this kind of steel plate constitutes the main structure of the ship and bears various loads such as seawater pressure, cargo weight and wave impact.

Design requirements: In addition to having good mechanical properties, shipbuilding steel plates also need to meet the requirements of ship design specifications for fire prevention, anti - corrosion, weldability and other aspects. For example, in terms of anti - corrosion, in addition to the above - mentioned shot blasting treatment and surface coating, the chemical composition of the steel may also be optimized by adding an appropriate amount of corrosion - resistant elements.

The following are some application cases of Grade LRA Shotblasted SA2.5 Shipbuilding Steel Plate:

 

Application in large merchant ships

 

Container ships

Application parts and methods: It is widely used in parts such as the hull shell and hatch coaming of container ships. The hull shell is in direct contact with seawater and needs to withstand the corrosion of seawater, the impact of waves, and the pressure after loading goods. After the Grade LRA Shotblasted SA2.5 steel plate is shot - blasted, the surface roughness increases, and the anti - corrosive paint applied can adhere better, effectively resisting the erosion of seawater. For example, for a large container ship with a loading capacity of 8000 TEU (Twenty - foot Equivalent Unit), its hull shell is made of this kind of steel plate, which can reduce the number of maintenance times during the 20 - to 30 - year operation cycle and ensure the normal operation of the ship.

Bulk carriers

Application parts and methods: It is mainly used in parts such as the bottom of the cargo hold and the side structure of bulk carriers. When bulk carriers transport bulk goods such as coal and ore, the bottom of the cargo hold and the side will bear the friction and impact of the goods. The high strength and good toughness of this steel plate can withstand these external forces. At the same time, the surface after shot blasting can be better anti - corrosive treated to prevent the moisture and corrosive substances in the goods from damaging the steel plate. For example, for a 100,000 - ton bulk carrier, the bottom of its cargo hold is made of this steel plate. When transporting highly corrosive goods such as high - sulfur ores, it can effectively reduce the corrosion rate.

 

Application in special ships

 

Chemical tankers

Application parts and methods: It is used in the liquid cargo tank wall and double bottom structure of chemical tankers. The chemicals transported by chemical tankers are diverse, and many chemicals are corrosive to the tank wall. The surface treatment grade and chemical composition optimization of the Grade LRA Shotblasted SA2.5 steel plate make it have good corrosion resistance and can meet the transportation requirements of different chemicals. For example, when transporting extremely corrosive chemicals such as strong acids and strong alkalis, using this kind of steel plate for the liquid cargo tank wall can effectively prevent chemical leakage and ensure the safety of the ship and the environment.

LNG ships (liquefied natural gas ships)

Application parts and methods: It is applied in key parts such as the liquid cargo tank containment system and the secondary shielding layer of LNG ships. LNG ships need to store and transport liquefied natural gas at extremely low temperatures, and the containment structure of the liquid cargo tank faces the dual challenges of low temperature and internal pressure. This steel plate not only meets the requirements of strength and toughness but also can maintain good performance in a low - temperature environment after shot blasting and specific anti - corrosion treatment. For example, using this steel plate in the secondary shielding layer of the liquid cargo tank can prevent natural gas leakage and ensure the safe operation of the ship.
