ASTM B861 GR.2 UNS R50400 Titanium Unalloyed Pipe For High Corrosion Resistance
ASTM B861 GR.2 UNS R50400 Titanium Unalloyed Pipe manufactured from commercially pure, unalloyed Titanium Grade 2. This material identified by the Unified Numbering System (UNS) designation R50400, is characterized by its excellent balance of moderate strength, superior ductility, and outstanding formability. Its primary value lies in its exceptional resistance to corrosion across a wide range of environments, particularly in chloride-containing media such as seawater, brines, and oxidizing acids, where stainless steels would typically fail. These seamless pipes are produced without a longitudinal weld, ensuring enhanced structural integrity, uniform mechanical properties, and superior reliability for high-pressure and critical applications in aggressive service conditions. They are a cornerstone material in industries like chemical processing, offshore oil and gas, marine engineering, and power generation condensers.

2. Key Adventages
High Strength-to-Weight Ratio: Provides strength comparable to some steels at nearly half the weight, leading to more efficient and lightweight system designs.
Seamless Integrity: Manufactured without a longitudinal weld, eliminating a potential failure point and ensuring uniform microstructure and mechanical properties throughout the pipe's circumference, ideal for high-pressure applications.
Excellent Fabricability: Possesses good ductility and formability, allowing for easier bending, flaring, and welding compared to higher-strength titanium alloys.
Biocompatibility: Grade 2 titanium is biocompatible, making it suitable for pharmaceutical, food processing, and bio-medical applications.
3. Key Applications
Oil & Gas: Offshore platform piping, risers, heat exchanger tubes in seawater cooling systems.
Power Generation: Condenser and heat exchanger tubes in coastal and nuclear power plants.
Marine & Offshore: Seawater piping systems, ballast systems, firewater lines.
Aerospace: Hydraulic lines and tubing for non-structural components.
Pharmaceutical & Food: Process equipment where product purity and corrosion resistance are paramount.
Pulp & Paper: Bleach plants and equipment handling corrosive liquors.
