ASTM B862 Ti2 Titanium Welded Pipes For Heat Exchanger

ASTM B862 Ti2 Titanium Welded Pipes , For Heat Exchanger

ASTM B862 is a specification that covers the requirements for welded titanium and titanium alloy pipes. Among the titanium grades, Grade Ti2 (Titanium Grade 2) is one of the most commonly used due to its excellent combination of strength, corrosion resistance, and weldability.

Key Features of ASTM B862 Ti2 Titanium Welded Pipes:

• Material Composition:

  • Grade Ti2 is a commercially pure titanium (CP Ti) material.
  • It contains around 99.2% titanium, with small amounts of iron and oxygen to enhance strength and corrosion resistance.

• Corrosion Resistance:

  • Grade Ti2 titanium pipes exhibit excellent resistance to a wide range of corrosive environments, including seawater, chlorides, and acidic mediums.
  • This makes them ideal for applications in the chemical, marine, and power generation industries.

• Strength and Ductility:

  • Grade Ti2 offers moderate strength but excellent ductility, making it suitable for forming and welding operations.

• Weldability:

  • The pipes are welded using advanced techniques that ensure the integrity of the welds while maintaining the material's corrosion resistance and mechanical properties.

• Applications:

  • Commonly used in industries such as aerospace, chemical processing, desalination plants, heat exchangers, and medical equipment.

• Standards and Dimensions:

  • The pipes are manufactured and tested according to the ASTM B862 standard, ensuring compliance with rigorous mechanical and chemical requirements.
  • They are available in different sizes, wall thicknesses, and lengths to meet diverse industrial requirements.

Advantages of Ti2 Titanium Welded Pipes:

• Lightweight and high strength-to-weight ratio.
• Excellent biocompatibility for medical and pharmaceutical applications.
• Resistance to erosion and corrosion in extreme environments.
• Long service life with minimal maintenance.

Typical Industries Using ASTM B862 Ti2 Pipes:

• Chemical Processing: For handling corrosive chemicals and fluids.
• Desalination: Piping in seawater desalination plants.
• Aerospace: Lightweight and durable piping for critical systems.
• Marine: Corrosion-resistant pipes for shipbuilding and offshore platforms.
• Medical: For surgical tools and implants due to biocompatibility.
