ASTM B862 UNS R50400 Titanium Alloy Welded Pipe

If you're searching for high-performance titanium welded pipes for chemical processing, seawater desalination, or aerospace systems, ASTM B862 UNS R50400 titanium alloy welded pipes are an excellent choice. Manufactured to ASTM B862 standards using commercially pure Grade 2 titanium (UNS R50400), these pipes deliver exceptional corrosion resistance, strength, and weldability.

 

GNEE maintains an inventory of ASTM B862 Grade 2 titanium pipes. As a widely used titanium mill product, ASTM B862 UNS R50400 titanium pipe is favored for its outstanding formability, moderate strength, and superior corrosion resistance in both oxidizing and weakly reducing environments.

Our ASTM B862 Grade 2 titanium welded pipes are approximately 45% lighter than steel while offering a high strength-to-weight ratio. They are suitable for TIG, MIG, or resistance welding methods, exhibit exceptional resistance to seawater, chlorides, and oxidizing acids, and maintain stable mechanical properties at temperatures up to 400°C (752°F).
Additionally, these titanium alloy welded pipes comply with ASME SB/ASTM B862 standards for Grades 1, 2, 3, 5, 7, 8, 9, 11, 12, and 23. They have been certified and tested through hardness testing, hydrostatic testing, eddy current inspection, tensile testing, flattening, flaring, annealing, hydrostatic testing, tempering, and stress relief to ensure reliability and performance.
