Titanium Grade 2 Tubing
Titanium Grade 2 Tubing
Titanium Grade 2 is a commercially pure titanium. It is the most commonly used grade of titanium because of its strength, weldability, and outstanding resistance to corrosion. Good ductility and formability make it a popular alloy choice for tubing or piping systems, heat exchangers, reaction and pressure vessels, and flue-gas desulphurization systems. Titanium Gr2 is used across industries such as chemical processing, petrochemical processing, aerospace, and marine.

Fabrication
Titanium Grade 2 responds well to cold forming using standard methods. It can be readily machined, but special attention must be paid to maintaining sharp tools and the liberal use of coolant. As with machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.
Industry Applications
Aerospace
Due to its good tensile strength and high melting point, titanium Grade 2 is used to withstand high pressures and heat situations, which are commonly seen in the aerospace industry. Typical applications include titanium tubing used in reactor autoclaves.
Chemical Process
Commonly used for chlorate manufacturing, Titanium Grade 2 tubing’s corrosion resistance properties make the alloy an ideal choice for chemical processing applications, which are needed, for example, in refineries and petrochemical plants.
Marine
Known for its ability to provide excellent service in aggressive chloride-containing environments commonly seen in the marine industry, titanium Grade 2 is an excellent choice for heat exchangers and seawater cooling applications, as well as desalination equipment.
Oil & Gas
Oil and gas components needed for offshore oil rigs in the oil and gas industry can rely on Grade 2 titanium tubing for cost effectiveness and corrosion resistance properties.
Power Generation
In the power generation industry, heat exchangers for geothermal wells require an alloy that can withstand exposure to geothermal or high-salinity brines. Grade 2 titanium tubing’s corrosion resistance properties make it an excellent choice.
Pulp & Paper
In the pulp and paper industry, titanium Grade 2 tubing is used for bleaching environments where chloride is present due to its corrosive resistance properties.
