Product Description
Description
Big OD (large outer diameter) titanium welded tubes are manufactured from high-quality titanium metal and designed for applications requiring high strength, low weight, and exceptional corrosion resistance.
These tubes, produced to ASTM B862 standards, are widely used in medical, industrial, and aerospace fields where durability and performance are critical.
Compared with traditional steel or aluminium tubes, titanium welded tubes offer:
Superior corrosion resistance
Excellent mechanical strength
Lightweight design
High temperature and fatigue resistance
Titanium Gr1 welded tubes are commonly used in medical implants, while Ti Gr2 welded tubes are popular in industrial equipment such as heat exchangers, condensers, and chemical process systems.
