ASTM Standard Specification for Tubes Made of Titanium and Titanium Alloys: Frequently Asked Questions
1. What is the ASTM standard for tubes made of titanium and titanium alloys?
The ASTM standard for tubes made of titanium and titanium alloys is defined by ASTM B861 for non‐welded tubes and ASTM B862 for welded tubes. These standards set clear requirements for use in corrosion‐resistant and high‐temperature applications.
2. Which titanium grades are covered by the ASTM standard?
The ASTM standards cover several titanium grades. These include unalloyed titanium grades (commonly Grade 1 and Grade 2), Grade 5 (Ti-6Al-4V) and Grade 9 (Ti-3Al-2.5V). Each grade exhibits specific chemical compositions and mechanical properties.
3. How are titanium tubes manufactured in accordance with the ASTM standard?
Titanium tubes are produced by different methods. Non‐welded tubes are manufactured using processes such as extrusion or rotary piercing, followed by cold forming and annealing. Welded tubes are formed from sheet or plate, then joined using a gas-shielded welding process and subsequently heat treated to relieve stresses.
4. Which tests and inspections are required?
The ASTM standards require several tests to verify mechanical properties and quality. These include tensile tests, hydrostatic or pneumatic pressure tests, flattening tests and non‐destructive tests such as ultrasonic or radiographic inspections. Chemical analysis is also performed to verify the composition.
5. How are tube size and wall thickness determined?
Tube size and wall thickness are specified according to the ASTM standards. They are generally based on the tube schedules published by the American National Standards Institute (ANSI). The standards contain detailed dimensions for nominal pipe sizes and corresponding wall thicknesses.
6. Can titanium tubes be used in high-temperature applications?
Titanium and its alloys possess high strength-to-weight ratios and corrosion resistance at elevated temperatures. Most titanium tubes can be used up to 316°C (600°F). Some alloys may perform at higher temperatures, subject to their specific composition.
7. What are the main applications of ASTM-specified titanium tubes?
Tubes that comply with ASTM standards are used in applications that require high strength, low weight and excellent corrosion resistance. They are employed in hydraulic systems in the aerospace sector, chemical processing facilities, power generation plants, desalination installations and offshore drilling operations. Owing to its biocompatibility, titanium is also used in medical devices and implants.
