Application
Heat Exchangers, Condensers, Coolers, Etc.
Product Overview
The ASTM B861 GR2 Titanium Heat Exchanger Tube offers unmatched corrosion resistance, moderate strength, and reliability in extreme environments, making it a premium choice for critical thermal applications. Its seamless construction and rigorous testing ensure longevity and efficiency in demanding industrial settings.
Grade 2 titanium (UNS R50400), classified as commercially pure (CP) titanium.
Chemical Composition
Titanium (Ti): ≥ 98.9%
Iron (Fe): ≤ 0.30%
Oxygen (O): ≤ 0.25%
Nitrogen (N): ≤ 0.03%
Carbon (C): ≤ 0.08%
Hydrogen (H): ≤ 0.015%
Note: Grade 2 is unalloyed but may contain trace elements; it is not a traditional alloy like Grade 5 (Ti-6Al-4V).
Manufacturing Standard
ASTM B861: Specifies requirements for seamless titanium and titanium-alloy tubes for condensers and heat exchangers. Covers Grades 1-38, with GR2 being common for corrosion resistance.
Manufacturing Process
Seamless Construction: Produced via pilgering or extrusion to ensure uniformity and strength.
Cold Worked and Annealed: Enhances mechanical properties and ductility.
Dimensions and Tolerances
Diameter: Typically 1/8" to 5" OD, with custom sizes available.
Wall Thickness: Ranges from 0.028" to 0.165", adhering to ASME B36.19M.
Length: Standard lengths up to 12m; ends may be plain, beveled, or threaded per application needs.
Tolerances: Strict adherence to ASTM B861 for OD (±0.005"), WT (±10%), and straightness.
Mechanical Properties
Tensile Strength: ≥ 345 MPa (50 ksi)
Yield Strength (0.2% offset): ≥ 275 MPa (40 ksi)
Elongation: ≥ 20% in 2 inches
Hardness: ≤ 140 HB (Brinell)
Applications
Heat Exchangers for Corrosive Environments: GR2 titanium is highly resistant to a wide range of chemicals, including hydrochloric acid, sulfuric acid, and chlorides. Ideal for chemical and petrochemical plants processing highly corrosive substances.
Reactors and Cooling Systems: Used in petrochemical plants to withstand aggressive corrosive media and high-temperature conditions.
Marine Heat Exchangers: Perfect for ships, offshore platforms, and marine equipment where seawater corrosion is a major concern.
Offshore Oil and Gas Platforms: Used in cooling systems, water treatment systems, and heat exchange equipment to protect against corrosion in harsh marine environments.
