Titanium tube is a type of pipe that is used in a wide variety of industrial applications. It is approximately 40% lighter than steel and is extremely resistant to corrosion. In 2026, this hollow, cylindrical tube made of titanium or titanium alloys will play a key role in key industries such as aerospace, medical, chemical, and marine engineering.

What is Titanium Tube? Definition

Titanium pipes is a hollow cylindrical product made from titanium and titanium alloys by specialized processes. Customized titanium tubes sizes, thicknesses and lengths are available to meet different industrial needs.

As one of the important processing forms of titanium raw materials, titanium tube has the core qualities of titanium metal, and at the same time, by virtue of its hollow structure, it becomes an ideal choice for fluid transportation and heat exchange scenarios, and it is one of the core components for realizing high-efficiency transportation and heat exchange.

Core Advantages of Titanium Tube

Compared to traditional tubing, the advantages of titanium tube focus on five major aspects: strength, weight, corrosion resistance, high temperature resistance and biocompatibility, each of which corresponds to the core needs of key industries.

High Strength - Light Weight

The density of titanium is only 4.5g/cm³, while the density of stainless steel is 7.7-8g/cm³. titanium tubes is 40%-42% lighter than stainless steel tubing, and titanium tubes is even lighter than ordinary steel tubing.

In weight-sensitive areas such as aerospace and automotive, every kilogram of weight lost can significantly improve fuel efficiency or operational performance. Lightweight titanium tube is also easier to handle and install during installation.

Strong corrosion resistance

The corrosion resistance of titanium tubes is one of its core strengths, far exceeding that of stainless steel tubing. titanium tubes can effectively resist erosion by seawater, marine atmosphere, chlorine-containing solutions, all kinds of acids and alkalis, as well as oxidizing, reducing and other complex working conditions. In the chlorine-containing environment, stainless steel pipe is prone to pitting and stress corrosion cracking, while titanium pipe can perfectly avoid this problem.

High Temperature Resistance

Unlike many metal materials, titanium can maintain stable mechanical properties at high temperatures and is not easy to soften or deform.

Some titanium alloys can operate continuously at temperatures as high as 600°C (1112°F), while the upper limit of the applicable temperature of ordinary industrial pure titanium can be up to 350°C. For high-temperature conditions, high-temperature-resistant titanium alloys are required, which can withstand temperatures up to 550°C or more.

Good biocompatibility

Titanium is a metal with excellent biocompatibility, in contact with human tissue, will not produce allergies, rejection and other adverse reactions, and will not corrode, but also with the human skeleton, tissue fusion.

At the same time, titanium is non-toxic and non-magnetic and will not interfere with the normal operation of medical equipment. This characteristic makes titanium tubes the material of choice in the medical field.

Difference Between Titanium tube and Steel Tube

Compared to conventional steel, stainless steel and other alloy tubes, titanium tubes are strong, lightweight and corrosion-resistant. Traditional steel tubing is still strong, but heavy and prone to corrosion; stainless steel tubing has limited corrosion resistance and is easily damaged in harsh environments.

Common Types of Titanium Tube

The difference in performance of titanium tubes stems mainly from the different grades of titanium alloy used in it. Below are the four most common grades of titanium tubes, corresponding to different industry needs.

Grade 2 titanium (industrially pure titanium)

Grade 2 titanium is industrially pure titanium with no other alloying elements added, and is one of the most commonly used grades of titanium tubes. Its core strengths are excellent corrosion resistance, good moldability and moderate strength at a relatively low cost and low processing difficulty.

Since it is not necessary to take on high strength requirements, pure titanium tubes is widely used in industrial scenarios that do not require high strength, such as heat exchangers, condensers, chemical processing equipment, and marine components.

Grade 5 Titanium (Ti-6Al-4V)

Grade 5 titanium is an alpha-beta type titanium alloy and is the most widely used grade of titanium alloy - more than 50% of global titanium alloy usage is accounted for by grade 5 titanium.

Grade 5 titanium pipe has excellent strength, weldability, formability and corrosion resistance, with thermal properties and stiffness comparable to commercial titanium, and strength up to 900MPa or more, making it suitable for structural components.

Grade 9 Titanium (Ti-3Al-2.5V)

Grade 9 titanium is also an alpha-beta type titanium alloy, with core advantages of good ductility, high strength, excellent corrosion resistance, as well as cold working and welding, and excellent molding properties.

Grade 9 titanium pipe is used in the aerospace field for the manufacture of components such as aircraft hydraulic systems, aircraft honeycomb panels, etc. The applications of titanium tubes also cover the fields of medicine, dentistry, marine and sports, which makes it a more versatile grade of titanium tubes.

Grade 12 Titanium (Ti-0.3Mo-0.8Ni)

Grade 12 titanium has two alloying elements, molybdenum and nickel, and its core strengths are corrosion resistance and creep resistance at high temperatures, excellent weldability, and strength comparable to that of No. 2 titanium.

Grade 12 titanium is used in high-temperature industrial processing, chemical equipment and other scenarios, especially suitable for equipment that needs to operate for a long time in a high-temperature, corrosive environment, which can effectively extend the service life of the equipment.

Precision Manufacturing of Titanium Tube

The excellent performance of titanium pipe depends not only on the grade of titanium alloy, but also on the precision manufacturing process and strict quality control.

Seamless titanium tubes

Seamless titanium pipes are mainly produced by extrusion or pilger milling process, without welding, with higher overall sealing and strength, and better dimensional accuracy.

The production process involves multiple steps such as titanium sponge melting, ingot billeting, tilting and piercing, hot extrusion, etc. The vacuum self-consuming arc furnace melting temperature needs to be over 1700°C, and the melting should be repeated 2-3 times in order to eliminate segregation, while the electron beam cold-bed furnace is used for production of aerospace-grade titanium tubes, which can control the content of impurity oxygen to less than 0.12%.

COMBAT offers titanium tubes in different sizes, with outside diameters ranging from a few millimeters to hundreds of millimeters and wall thicknesses customized to requirements.

Welded titanium tubes

Welded titanium tubes are mainly produced by laser or TIG (Tungsten Inert Gas Welding) processes and are suitable for the production of thin-walled titanium tubes down to a wall thickness of 0.5 mm.

The production process includes titanium strip coil molding, argon gas protection welding, cold rolling wall reduction, intermediate annealing and other processes, the intermediate annealing temperature needs to be controlled at 650-750 ℃, in order to eliminate work hardening.

For example, the outer sleeve of minimally invasive surgical instruments and injection needle tubes can be as low as 0.5mm titanium tube OD.

Strict quality control

Titanium tube quality control is particularly stringent and relies heavily on a variety of non-destructive testing (NDT) methods to ensure quality.

Eddy current testing is a commonly used method for titanium tubes, which can detect defects as small as 0.1mm, ensuring that the tubing is free of cracks, porosity, etc. For titanium tubes used in aerospace hydraulic systems, 100% ultrasonic testing is conducted in accordance with AMS 4928 standards, eliminating any potential defects.

In addition, wall thickness deviation will be monitored by laser calibrator to ensure dimensional accuracy, industrial tubes need to be hydrostatic, flaring and other performance tests in accordance with GB/T 3625 standards, the surface will be removed by pickling (using a mixture of HF+HNO₃, the concentration of which is controlled at 5%-10%) to remove oxidized skin, and some of the high-end products will be polished so that the roughness Ra ≤ 0.2μm.
