Titanium Seamless Pipe for Ships

• Excellent corrosion resistance

Titanium content ≥ 99.5%, through the self-healing mechanism of surface oxide film, the annual corrosion rate in seawater, nitric acid and neutral salt solutions is less than 0.02mm, and the resistance to Cl ⁻ corrosion is better than 316L stainless steel. Typical applications include seawater desalination equipment (5000 meter deep sea environment) and chlor alkali industry electrolytic cells, with a lifespan of more than three times that of stainless steel.

• Mechanical performance balance

Tensile strength ≥ 240MPa, yield strength 170-310MPa, elongation ≥ 24%. Through vacuum melting and cold rolling process, it has excellent fatigue resistance. Cold bending test shows that pipes with an outer diameter of ≤ 25mm can be bent 90 ° without cracks, making them suitable for installation in complex pipelines.

• Strong process adaptability

The specifications cover an outer diameter of 3-300mm with a wall thickness of 0.2-15mm, and support customization of coils (≤ 3000mm) or straight sections (≤ 9000mm). Welding requires high-purity argon gas (≥ 99.99%) protection, and the weld strength should reach over 90% of the base metal. The surface can be customized with acid wash or bright annealing to meet the flow requirements of different media.

• In the field of chemical engineering, replacing stainless steel with reactor coils and heat exchanger bundles can reduce equipment weight by 40% -60% and maintenance costs by more than 50%.
• Medical field: Orthopedic implants (such as bone nails), medical equipment tubing, ensuring long-term implantation safety.
• Ocean engineering: deep-sea detector pressure resistant shell, seawater transportation pipeline, no risk of stress corrosion cracking in salt spray environment.
• Power industry: Condenser tubes for nuclear power plants, resistant to high temperature and high pressure steam corrosion, with a service life of over 20 years.

Technical Parameter

• Chemical composition: Ti ≥ 99.5%, Fe ≤ 0.20%, O ≤ 0.18%, in accordance with ASTM B337 and GB/T 3624-2023 standards;
• Certification support: ISO 9001 certification.

Quality Assurance

• Adopting vacuum consumable melting+precision rolling process, the entire process passes ultrasonic testing and third-party mechanical performance testing. The surface of the product is treated with acetone degreasing and acid washing, and sealed in moisture-proof packaging.
