Corrosion-resistant plate escorts the safety of ships

The steel for offshore platforms was developed on the basis of hull structural steel. The steel platforms initially constructed were made of hull structural steel. However, with the development of the marine industry, oil development has gradually developed from shallow seas to deep seas, from warm seas to low-temperature cold seas. Offshore platforms have to withstand various climatic conditions and wind and waves, are corroded by seawater, and the working environmental conditions are very harsh.
 
Secondly, the trend of large-scale structure is obvious, the structure is complex, the welding workload is large, and the welding of the nodes is already difficult. In addition, the concentration of stress is high, and the structure is in a more dangerous state; The danger is increasing. Therefore, in order to ensure the safe and reliable operation of the offshore platform, higher requirements are imposed on the steel used than the hull structural steel.
 
The corrosion of steel has knocked down many bridges and ships in the world and killed many people. At nuclear power plants, corrosion has killed at least dozens of lives, almost caused the melting of nuclear reactors, and threatened stored nuclear waste.
 
No matter day or night, you will hear the sound of metal rust. Corrosion is attacking doors, chassis, bearings, bridges, and ships. Many companies use corrosion-resistant plates to design ships and bridges, special alloys such as low-alloy plates and pressure vessel plates have strong bearing pressure, and corrosion-resistant plates have high corrosion resistance, which provides protection for the safety of bridges and ships in the world.
 
Even so, corrosion still occurs secretly. Therefore, studying the principle of electrochemical corrosion, strengthening the construction of corrosion-resistant plates and reusing special steels are of great significance to prevent metal corrosion from damaging the national economy.
