Frequently Asked Questions
What is Grade 2 Seamless Titanium Tube and why is Gr2 commonly used?
Grade 2 (Gr2) titanium is commercially pure titanium with excellent corrosion resistance, good formability, and moderate strength. It is one of the most widely used titanium grades for industrial tubing because it performs reliably in aggressive environments such as seawater, chemical processing, and high-temperature applications, while remaining cost-effective compared to higher-grade alloys.
What dimensional range is available for Grade 2 Seamless Titanium Tubes?
The standard dimensional range covers an outer diameter (OD) from Φ6mm to Φ120mm, wall thickness (WTH) from 0.1mm to 20mm, with customizable lengths. Custom sizes beyond these ranges can also be produced upon request to meet specific project requirements.
Which international standards do these titanium tubes comply with?
Grade 2 Seamless Titanium Tubes are manufactured in compliance with multiple 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 broad global acceptance and application.
What industries and applications are Grade 2 Seamless Titanium Tubes suitable for?
These tubes are widely used across numerous industries, including chemical processing, marine engineering, heat exchangers, firewater systems, ballast water systems, oil and gas, seawater desalination plants, and power generation stations. Their superior corrosion resistance and durability make them ideal wherever harsh or corrosive media are present.
Can Grade 2 Seamless Titanium Tubes be customized for special project needs?
Yes. Beyond the standard dimensional range, custom sizes, lengths, wall thicknesses, and surface finishes can be accommodated. Customers are encouraged to provide their specific technical drawings or project requirements so that a tailored solution can be offered.
How does Grade 2 Titanium compare to other titanium grades for tube applications?
Grade 2 titanium offers an optimal balance of corrosion resistance, weldability, ductility, and cost for most industrial tube applications. While higher grades like Gr5 (Ti-6Al-4V) provide greater strength, Gr2 is preferred where superior corrosion resistance and ease of fabrication are the primary requirements, particularly in aqueous, chloride-rich, and oxidizing environments.
