To Know About Titanium Tube

Titanium tube has the advantages of light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine tube heat exchanger, condenser, evaporator and conveying pipeline. Many nuclear power plants use titanium tube as the standard tube for their units.

⚡

High Strength

Tensile strength of titanium alloy is 686–1176 MPa, with density only ~60% of steel, delivering exceptional specific strength.

🛡️

Superior Corrosion Resistance

Forms a thin, dense oxide film rapidly in air below 550°C, outperforming most stainless steels in oxidizing media including sea water, nitric acid, sulfuric acid and strong alkali.

🏥

Biocompatible

Biocompatible and nonmagnetic — ideal for medical devices and increasingly important as MRI use grows in medical diagnostics.

🔬

The seamless titanium tube has a hardness (annealed) of HRC 32–38. Its corrosion resistance is superior to most stainless steels in oxidizing environments such as atmosphere, sea water, nitric acid, sulfuric acid and strong alkali.

Just as there are different types of stainless steel, copper, and nickel, there are many different grades of titanium tube. ASTM has a variety of standards (principally ASTM B338/ASME SB338, ASTM B265/ASME SB265, ASTM B348/ASME SB348, and ASTM B381/ASME SB381) relating to the "recipes" for titanium grades used in different applications.

📋 Available Titanium Grades

Multiple grades are available for unalloyed titanium under ASTM standards:

GR1 GR2 GR5 GR7 GR9 GR12

Frequently Asked Questions

❓ What are the main advantages of titanium tubes?

Titanium tubes offer light weight, high tensile strength (686–1176 MPa), superior corrosion resistance in harsh environments (sea water, nitric acid, sulfuric acid, strong alkali), and excellent biocompatibility. Their density is only about 60% of steel, resulting in a very high specific strength.

❓ What industries commonly use titanium tubes?

Titanium tubes are widely used in heat exchange equipment (tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers), condensers, evaporators, conveying pipelines, nuclear power plants, and medical devices.

❓ What ASTM standards apply to titanium tubes?

The principal ASTM standards for titanium tubes include ASTM B338/ASME SB338, ASTM B265/ASME SB265, ASTM B348/ASME SB348, and ASTM B381/ASME SB381. These standards define the composition and mechanical property requirements for various titanium grades.

❓ What grades of titanium tube are available?

Common titanium grades include GR1, GR2, GR5, GR7, GR9, and GR12. Each grade has different mechanical properties and is suited to specific applications — for example, GR1 and GR2 are unalloyed and highly corrosion-resistant, while GR5 (Ti-6Al-4V) offers the highest strength.

❓ Why is titanium tube used in medical devices?

Titanium is biocompatible, meaning the human body can tolerate it without adverse reactions. It is also nonmagnetic, which is increasingly important as MRI (magnetic resonance imaging) becomes more common in medical diagnostics. These properties make titanium tubes ideal for medical implants and instruments.

❓ What is the hardness of seamless titanium tube?

In the annealed condition, seamless titanium tube has a hardness of HRC 32–38. Combined with its high tensile strength and low density, this makes it a highly efficient structural material for demanding industrial applications.
