ASME SB338 / ASTM A338 GR.7 Titanium Alloy Seamless Tubes

ASME SB338 / ASTM A338 GR.7 Titanium Alloy Seamless Tubes

ASME SB338 / ASTM A338 Gr.7 seamless titanium tubes are high-performance alloy tubes specifically designed for demanding industrial applications. These tubes are manufactured in accordance with the standards set by the American Society of Mechanical Engineers (ASME) and the American Society for Testing and Materials (ASTM), ensuring exceptional quality and reliability.

Key Features

• Material Composition
  Grade 7 titanium alloy is primarily composed of titanium with a small addition of palladium (0.12%-0.25%) for enhanced corrosion resistance. This makes it especially suitable for use in aggressive chemical environments.

• Excellent Corrosion Resistance
  Titanium Grade 7 exhibits outstanding resistance to corrosion, particularly in oxidizing and reducing conditions, including exposure to chloride-rich environments and acidic solutions.

• High Strength-to-Weight Ratio
  The seamless titanium tubes offer a superior strength-to-weight ratio, making them lightweight yet capable of withstanding high pressure and stress.

• Thermal and Mechanical Properties
  The alloy demonstrates excellent mechanical performance, good thermal stability, and high resistance to cracking even in extreme temperature fluctuations.

Applications

• Chemical Processing: For equipment exposed to corrosive substances.
• Aerospace: Lightweight and durable tubing for critical structural components.
• Marine and Offshore: Piping systems in seawater environments.
