Frequently Asked Questions
Q
What is Grade 2 Seamless Titanium Tube, and how does it differ from other titanium grades?
A
Grade 2 (Gr2) is commercially pure titanium with excellent corrosion resistance and good formability. Compared to higher grades such as Gr5 (Ti-6Al-4V), Gr2 offers superior weldability and is preferred for applications requiring resistance to aqueous and chemical environments rather than high structural strength.
Q
What size range is available for Grade 2 Seamless Titanium Tubes?
A
Standard dimensions cover an outer diameter (OD) from Φ6mm to Φ120mm and a wall thickness (WTH) from 0.1mm to 20mm. Custom lengths and non-standard sizes can also be manufactured upon request.
Q
Which international standards do these titanium tubes comply with?
A
The tubes comply with a wide range of international standards, including ASTM B338, ASTM B861, ASTM B862 (USA), GB/T3624, GB/T3625 (China), ΓOCT21945, ΓOCT22897, ΓOCT24890 (Russia), JIS H4631 (Japan), and DIN17861, DIN17866 (Germany), ensuring global applicability.
Q
What are the main application areas for Grade 2 Seamless Titanium Tubes?
A
These tubes are widely used in the chemical industry, marine engineering, heat exchangers, firewater and ballast water systems, oil and gas industry, seawater desalination plants, and power stations — wherever high corrosion resistance and long service life are critical requirements.
Q
Why choose seamless titanium tubes over welded titanium tubes?
A
Seamless titanium tubes have no weld seam, which eliminates potential weak points and provides superior pressure resistance, structural integrity, and uniform corrosion resistance. They are the preferred choice for high-pressure, high-temperature, or highly corrosive environments such as heat exchangers and offshore systems.
Q
Can Grade 2 Seamless Titanium Tubes be customized for special project requirements?
A
Yes. Beyond the standard size range, custom outer diameters, wall thicknesses, lengths, and surface finishes can be produced to meet specific engineering or project specifications. Please provide your technical drawings or requirements for a tailored quotation.
