Frequently Asked Questions
Q
What is Grade 2 (Gr2) titanium, and why is it used for seamless tubes?
Grade 2 titanium is commercially pure titanium with a minimum purity of approximately 99.2%. It offers an excellent balance of strength, ductility, and corrosion resistance, making it the most widely used titanium grade for seamless tubing in industrial applications such as heat exchangers, chemical processing, and marine systems.
Q
What size range is available for Grade 2 Seamless Titanium Tubes?
The standard size range covers an outer diameter (OD) from Φ6mm to Φ120mm, a wall thickness (WTH) from 0.1mm to 20mm, and custom lengths. Custom dimensions beyond these ranges can also be produced upon request to meet specific project requirements.
Q
Which international standards do these titanium tubes comply with?
Grade 2 Seamless Titanium Tubes are manufactured in compliance 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 industries commonly use Grade 2 Seamless Titanium Tubes?
These tubes are widely used across multiple industries, including chemical processing, marine engineering, oil and gas, power generation, heat exchanger manufacturing, firewater systems, ballast water systems, and seawater desalination plants — all environments that demand high corrosion resistance and long service life.
Q
What are the key advantages of seamless titanium tubes over welded tubes?
Seamless titanium tubes offer superior structural integrity with no weld seams, which eliminates potential weak points and reduces the risk of corrosion at joints. They can withstand higher pressures and are preferred in critical applications such as high-pressure heat exchangers, subsea pipelines, and chemical reactors where reliability is paramount.
Q
Can custom dimensions and specifications be ordered?
Yes. In addition to the standard size range, custom OD, wall thickness, and length specifications are available. Customers can contact us with their specific project requirements, and our technical team will provide tailored solutions to meet exact dimensional, standard, and performance needs.
