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.

The seamless titanium tube has high strength. The tensile strength of titanium alloy is 686-1176mpa, and the density is only about 60% of that of steel, so the specific strength is very high. The hardness of titanium alloy (annealed) is HRC32-38. Seamless titanium tube also has strong corrosion resistance. Titanium at 550℃ in the air below, the surface will form thin and dense rapidly. Therefore, the corrosion resistance of titanium oxide film is better than that of most stainless steel in the oxidizing medium such as atmosphere, sea water, nitric acid and sulfuric acid and strong alkali.

Another great thing about titanium is that, just as there are different types of stainless steel, copper, nickel, there are many different grades of titanium tube.

Multiple ASTM Standards

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. Multiple grades exist for unalloyed titanium, e.g. GR1, GR2, GR5, GR7, GR9 and GR12 etc.

Biocompatible & Nonmagnetic

Another advantage of titanium tube in medical devices is that it is biocompatible. Not only can the human body tolerate the use of titanium, but it is also nonmagnetic — an increasingly important trait as the use of magnetic resonance imaging (MRI) becomes more common in medical diagnostics.

Frequently Asked Questions

Q What are the main advantages of titanium tubes?

Titanium tubes offer light weight, high strength, and superior mechanical properties. They are highly corrosion-resistant against oxidizing media such as atmosphere, sea water, nitric acid, sulfuric acid, and strong alkali, making them ideal for demanding industrial and medical applications.

Q What industries commonly use titanium tubes?

Titanium tubes are widely used in heat exchange equipment including tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators, and conveying pipelines. They are also a standard tube material in nuclear power plants and are used extensively in the medical device industry.

Q 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 specifications and "recipes" for various titanium grades used across different applications.

Q What are the common grades of titanium tubes available?

Common titanium tube grades include GR1, GR2, GR3, GR5, GR7, GR9, GR11, GR12, GR16, and GR17. Each grade has different tensile strength, yield strength, and elongation properties suited to specific applications, as detailed in the tensile requirements table above.

Q Why is titanium tube preferred in medical devices?

Titanium is biocompatible, meaning the human body can safely tolerate it. Additionally, titanium is nonmagnetic, which is increasingly important as magnetic resonance imaging (MRI) becomes more widely used in medical diagnostics. These properties make titanium tubes a preferred material for medical device manufacturing.

Q What is the tensile strength range of seamless titanium tubes?

The tensile strength of titanium alloy ranges from 686 to 1176 MPa. The density of titanium is only about 60% of that of steel, giving it a very high specific strength. The hardness of annealed titanium alloy is HRC32–38, making seamless titanium tubes exceptionally strong and lightweight compared to conventional steel tubes.
