The strength and corrosion resistance of marine flat bulb are key design considerations and are detailed below:
1. Strength:
Tensile strength: Marine flat bulb steel needs to have sufficient tensile strength to withstand various stress conditions that may occur in the ship structure, such as wind load, wave load, etc.
Yield strength: The yield strength of a material indicates the level of resistance at which it begins to deform. For marine spherical flat steel, this is an important parameter that affects the stability and safety of the structure.
2. Corrosion resistance:
Corrosion resistance in marine environment: Marine flat bulb steel usually needs to have excellent seawater corrosion resistance, because ships are in salt spray and humid marine environments, and long-term exposure to seawater can easily lead to corrosion.
Prevent electrochemical corrosion: Marine flat bulb steel may be in contact with other metal parts in the ship structure. The electrochemical compatibility between materials needs to be considered to avoid electrochemical corrosion.
Coating protection: Surface coating or anti-corrosion treatment can improve the corrosion resistance of marine flat bulb steel, extend its service life and reduce maintenance costs.
3. Testing and Certification:
Material testing: Evaluate the corrosion resistance of marine flat bulb steel through relevant testing methods (such as salt spray test, corrosion test, etc.).
Certification requirements: Marine flat bulbs may need to meet specific classification society standards or international certification requirements to ensure that their strength and corrosion resistance meet industry standards.
The strength and corrosion resistance of marine flat bulb steel directly affect the safety and reliability of the ship structure. These factors need to be considered comprehensively when designing and selecting materials.
