Frequently Asked Questions
What makes Grade 7 Titanium unique?
Grade 7 Titanium is a titanium alloy containing a small amount of Palladium (0.12% to 0.25%). This addition significantly enhances its corrosion resistance, especially in reducing acid environments and localized crevice corrosion.
What are the benefits of seamless titanium tubes?
Seamless tubes offer superior pressure handling capabilities and structural integrity compared to welded tubes. They are ideal for high-stress applications in heat exchangers and chemical processing.
Can I order custom dimensions for Gr7 tubes?
Yes, we provide customization for Outside Diameter (OD), Wall Thickness (WTH), and Length (L) to meet specific engineering requirements beyond the standard sizes.
Which international standards do your tubes comply with?
Our products meet a wide range of global standards including ASTM B338, ASTM B861, DIN 17861, JIS H4631, and GOST specifications, ensuring quality for international projects.
In which environments is Grade 7 most effective?
It is most effective in chemical processing and marine environments where dilute reducing acids or chlorides are present, offering the best corrosion resistance of all titanium grades.
What industries typically use Gr7 seamless tubes?
Key industries include desalination plants, oil and gas extraction, power generation, and marine engineering for firewater and ballast systems.
