Frequently Asked Questions
Q
What is Grade 12 Titanium (Gr12), and how does it differ from other titanium grades?
Grade 12 titanium is a titanium-molybdenum-nickel alloy (Ti-0.3Mo-0.8Ni) that offers superior corrosion resistance compared to commercially pure grades (Gr1–Gr4), especially in reducing acid environments and crevice corrosion conditions. It provides a strength level similar to Gr9 while maintaining excellent weldability and formability, making it ideal for demanding industrial applications.
Q
What size range is available for Grade 12 Seamless Titanium Tubes?
Standard dimensions cover an outer diameter (OD) from Φ6mm to Φ120mm, with wall thickness (WTH) ranging from 0.1mm to 20mm. Custom lengths and sizes beyond these ranges are also available upon request to meet specific project requirements.
Q
Which international standards do your Grade 12 Seamless Titanium Tubes comply with?
Our Grade 12 Seamless Titanium Tubes conform to a wide range of international standards, including ASTM B338, ASTM B861, ASTM B862 (USA), GB/T3624 and GB/T3625 (China), ΓOCT21945, ΓOCT22897, and ΓOCT24890 (Russia), JIS H4631 (Japan), as well as DIN17861 and DIN17866 (Germany), ensuring global compatibility and quality assurance.
Q
What are the main industries and applications for Grade 12 Seamless Titanium Tubes?
Grade 12 Seamless Titanium Tubes are widely used in the chemical industry, marine engineering, heat exchangers, firewater and ballast water systems, oil and gas pipelines, seawater desalination plants, and power stations. Their exceptional corrosion resistance and mechanical strength make them a preferred choice wherever aggressive media or saltwater environments are present.
Q
Why is Grade 12 Titanium preferred for seawater and marine applications?
The addition of molybdenum and nickel in Grade 12 titanium significantly enhances its resistance to crevice corrosion and pitting in chloride-rich environments such as seawater. This makes Gr12 tubes highly reliable for marine engineering, desalination plants, and offshore oil and gas systems where long-term performance and minimal maintenance are critical.
Q
Can Grade 12 Seamless Titanium Tubes be customized for special project requirements?
Yes. In addition to the standard size range, we offer customized dimensions including non-standard outer diameters, wall thicknesses, and lengths to suit specific engineering and project needs.
