Features Of High-strength Seamless Rectangular Tube For Ships
High strength: 610L material gives the rectangular seamless tube excellent tensile strength and yield strength, can withstand the various complex stresses encountered in the process of ship navigation.
Seamless process: Seamless production process ensures the uniformity and integrity of the internal structure of the steel pipe. This can avoid defects caused by welding and improve the overall performance and reliability of the product.
Rectangular section: This section design makes the product more flexible to adapt to various layout requirements in the ship structure, while providing a larger section moment of inertia, enhancing the bending ability of the structure.
Corrosion resistance: After special treatment, it has good resistance to seawater corrosion and can maintain stable performance in long-term offshore environment.
Easy to process: it has good weldability and plasticity, easy to process into a variety of shapes and sizes, to meet the diversified needs in the shipbuilding process.
Operation of Seamless Rectangular Tube
1. Handling and storage: during handling, scratches or impacts on seamless rectangular tubes should be avoided. Storage should be placed in a dry, well-ventilated environment and avoid prolonged exposure to sunlight or humid environment.
2. Cutting and welding: relevant operating procedures should be followed during cutting and welding to ensure a clean and safe operating environment. The welding area should be preheated before welding to improve the welding quality.
3. Installation and commissioning: during the installation process, the correct position and fixing mode of the steel pipe should be ensured. During debugging, the tightness and sealing performance of each connection part should be checked to ensure the stability and safety of the structure.
4. Maintenance: check and maintain steel pipes regularly to find and deal with potential problems in time. When used in harsh environment, anti-corrosion measures should be strengthened to extend the service life.
610L Marine high strength seamless rectangular pipe is widely used in the skeleton structure, support structure, deck structure and bulkhead structure of all kinds of ships. Its high strength and corrosion resistance make this product an ideal choice in the shipbuilding industry, helping to improve the overall performance and safety of ships.
