Applications

Titanium has proven to be an indispensable material across numerous industries due to its unique combination of strength, corrosion resistance, and light weight. It is widely used in:

Aerospace and aviation – for airframes, engines, and structural tubing

Chemical processing – for reactors, heat exchangers, and piping systems

Power generation – particularly in surface condensers and seawater cooling systems

Oil and gas – for offshore and subsea equipment

Marine industry – due to its resistance to seawater corrosion

Medical field – for surgical instruments and implants

Titanium tubes can be easily fabricated, welded, and formed for various industrial uses.
There are currently 38 titanium grades approved under ASME B338 and ASTM B338, including Grades 1, 2, 3, 7, 9, 11, 12, 16, 17, 26 (TiRU-26TM), and 27 (TiRU-27TM).
Among these, Grade 2 titanium is the most commonly used, especially for power plant surface condensers.

Typical titanium alloys used for tubing include Ti-3Al-2.5V and Ti-6Al-4V.
