Titanium Grade 2 Pipes - Composition Properties And Uses

Titanium is a metal known for its strength, lightness, and resistance to corrosion. It’s one of the most versatile metals, with applications ranging from aerospace and medical implants to jewelry and car parts. Among its many varieties is Titanium Grade 2, a popular choice for pipes in various industries. This blog post explores the composition, physical and mechanical properties, and common uses of Titanium Grade 2 pipes.


Titanium Grade 2 Pipes Composition

Titanium Grade 2, also known as Ti-2 or Commercially Pure Titanium (CP Ti), is a variant of titanium that contains 99.2% pure titanium. It also has trace amounts of iron, oxygen, carbon, nitrogen, and hydrogen. The absence of other alloys or metals makes it highly ductile and malleable, which enables it to be easily formed into pipes of different shapes and sizes. It also has excellent weldability and machinability, further enhancing its processing capabilities.

Titanium Grade 2 Pipes Physical Properties

WERKSTOFF NR. 3.7035 Hexagonal Pipe have a 4.5 grams per cubic centimetre density, about 60% less than steel. This makes them ideal for applications requiring lightweight yet strong materials, such as aerospace and marine engineering. They also have a high melting point of 1660℃, which makes them highly heat-resistant. Furthermore, they have a low thermal conductivity, making them suitable for insulation.

Titanium Grade 2 Pipes Mechanical Properties

Titanium Grade 2 Seamless Pipe can withstand a maximum temperature of 315℃ or 600℉. They have a tensile strength of 275 MPa (megapascals) and a yield strength of 250 MPa. They also exhibit a low elasticity modulus of 110 GPa (gigapascals), which means they can deform easily without breaking. These mechanical properties make them suitable for applications requiring strength and flexibility, such as chemical and petrochemical plants.

Titanium Grade 2 Pipes Uses

Titanium Grade 2 pipes have a wide range of uses across various industries. The aerospace industry uses them for components such as hydraulic lines, ducting, and exhaust pipes. In the marine industry, they’re used for piping systems in freshwater and seawater applications. The chemical industry uses them for processing equipment involving acids, chlorides, or other aggressive chemicals. They’re also used in medical implants, jewellery, and sporting goods.

Titanium Grade 2 Pipes Heat Treatment

Titanium Grade 2 pipes can be heat treated to enhance their strength and hardness. The heat treatment involves heating the pipes to a specific temperature, holding them there for a set time, and then cooling them down at a controlled rate. This process can improve their tensile and yield strength, making them even more resistant to deformation and breakage.

Titanium Grade 2 Pipes Corrosion Resistance

One of the most notable properties of Titanium Grade 2 pipes is their corrosion resistance. They’re highly corrosion-resistant to seawater, brine solutions, and other chloride-containing environments. They’re also resistant to other common acids and alkaline solutions. This corrosion resistance makes them a popular choice for applications that involve exposure to harsh environments, such as offshore oil rigs and desalination plants.


In conclusion, Titanium Gr2 alloy Pipe are versatile and reliable for various industrial and commercial applications. Their composition, physical and mechanical properties, and corrosion resistance make them ideal for aerospace, marine, chemical, and medical industries. Their heat treatment capabilities also make them customizable to specific needs. Overall, Titanium Grade 2 pipes are a valuable investment for anyone needing a lightweight and durable piping system.
