Seamless Grade 7 Titanium Tube from China Suppliers - Durable and Corrosion-Resistant Factory Direct Products

Grade 7 Titanium (Gr7) is a commercially pure titanium alloy with a small addition of palladium (0.12–0.25%), which significantly enhances its corrosion resistance — especially in reducing and oxidizing acid environments. Compared to Grade 2, Gr7 offers superior resistance to crevice corrosion and is ideal for more aggressive chemical and marine applications.

The standard dimensional range is OD Φ6–Φ120mm, wall thickness 0.1–20mm, with customizable lengths. For special project requirements, custom sizes beyond these ranges can also be accommodated upon request.

These tubes comply with a wide range of international standards, including ASTM B338, ASTM B861, ASTM B862 (USA), GB/T3624, GB/T3625 (China), ΓOCT series (Russia), JIS H4631 (Japan), and DIN17861, DIN17866 (Germany), ensuring compatibility with global project specifications.

Gr7 seamless titanium tubes are widely used in chemical processing, marine engineering, heat exchangers, firewater and ballast water systems, oil and gas pipelines, seawater desalination plants, and power stations — wherever high corrosion resistance and long service life are critical requirements.

Seamless titanium tubes are manufactured without any weld seams, resulting in a more uniform structure, higher pressure resistance, and better mechanical integrity. This makes them the preferred choice for high-pressure systems, corrosive media, and applications where reliability and leak-free performance are essential.

Yes. Beyond the standard dimensional range, custom OD, wall thickness, and length specifications are available. Surface finishing, heat treatment conditions, and compliance with specific project standards can also be tailored to meet the exact requirements of your engineering project.
