Product Description
ASTM B861 GR2 Titanium Seamless Pipe For Refining Equipment
Product Specifications
In refining equipment, the core function of ASTM B861 Gr2 titanium seamless pipes is to maintain equipment integrity and reliability in highly corrosive environments. The naturally formed dense titanium oxide protective film on its surface effectively resists corrosion from chlorides, sulfides, and organic acids, significantly extending equipment service life. Particularly in condensation systems of atmospheric and vacuum distillation units, catalytic cracking units, and acid water treatment pipelines, this material can withstand corrosion challenges under high temperature and pressure conditions, preventing equipment failures and production interruptions caused by pipeline corrosion. Meanwhile, the high strength-to-weight ratio of titanium pipes enables thin-wall design while maintaining mechanical performance, reducing system weight and improving equipment energy efficiency.
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%
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.
