Frequently Asked Questions
Q What is Grade 12 (Gr12) titanium and how does it differ from other titanium grades?
A Grade 12 titanium is a commercially pure titanium alloy containing small additions of molybdenum and nickel (Ti-0.3Mo-0.8Ni). Compared to Grades 1–4, Gr12 offers superior corrosion resistance — especially in reducing acid environments and high-temperature saline conditions — while maintaining excellent weldability and formability.
Q What size range is available for Grade 12 seamless titanium tubes?
A Standard sizes cover an outer diameter (OD) from Φ6mm to Φ120mm, with wall thickness (WTH) ranging from 0.1mm to 20mm. Custom lengths and dimensions beyond these ranges are also available upon request.
Q Which international standards do your Grade 12 seamless titanium tubes comply with?
A Our tubes are manufactured in compliance with a wide range of international standards, including ASTM B338, ASTM B861, ASTM B862, GB/T3624, GB/T3625, GOST 21945/22897/24890, JIS H4631, DIN 17861, and DIN 17866, ensuring compatibility with global engineering and procurement requirements.
Q What industries and applications are Grade 12 seamless titanium tubes best suited for?
A Grade 12 seamless titanium tubes are widely used in demanding environments including chemical processing plants, marine engineering, heat exchangers, firewater and ballast water systems, oil and gas pipelines, seawater desalination facilities, and power generation stations — anywhere high corrosion resistance and mechanical strength are critical.
Q Why is Grade 12 titanium preferred for seawater and marine applications?
A The nickel and molybdenum additions in Gr12 titanium significantly enhance its resistance to crevice corrosion and pitting in chloride-rich environments such as seawater. This makes it an ideal material for offshore platforms, desalination plants, and ballast water treatment systems where long-term durability is essential.
Q Can Grade 12 seamless titanium tubes be customized for special project requirements?
A Yes. In addition to the standard dimensional range, we offer customized sizes, lengths, and surface finishes to meet specific engineering or project requirements. Custom orders are welcome, and our technical team can assist with material selection, dimensional tolerances, and compliance documentation.
