Applications

Titanium has long proven to be an indispensable material in modern industry due to its combination of strength, corrosion resistance, and light weight.
It is widely used in the following sectors:

Aerospace and aviation: airframes, engine components, structural tubing

Chemical processing: reactors, piping systems, heat exchangers

Power generation: surface condensers, seawater cooling systems

Oil and gas: offshore and subsea equipment

Marine industry: desalination systems, seawater piping

Medical field: surgical instruments and implants

Titanium tubes can be easily fabricated, welded, and formed for a variety of industrial uses.
Currently, there are 38 titanium grades that meet ASME B338 and ASTM B338 standards for pressurised service.
Common grades include Gr1, Gr2, Gr3, Gr7, Gr9, Gr11, Gr12, Gr16, Gr17, Gr26 (TiRU-26TM), and Gr27 (TiRU-27TM).
Among these, Grade 2 titanium is most widely used, especially in power plant surface condensers.

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