(I) Corrosion Resistance
Performance in Chemical Environments
Titanium pipes exhibit excellent corrosion resistance to most organic acids, inorganic acids, alkalis, and salt solutions. For example, in environments containing chloride ions, such as seawater, titanium pipes demonstrate significantly better corrosion resistance than stainless steel. This is because titanium forms a stable, protective oxide film on its surface, preventing further reaction between the medium and the titanium substrate. In marine environments, titanium pipes can be used in seawater desalination plants, ship cooling systems, etc., effectively resisting seawater erosion and greatly extending the service life of equipment.
Corrosion Resistance in Different Industrial Media
In the chemical industry, titanium pipes can withstand corrosion from highly corrosive acids such as sulfuric acid, hydrochloric acid, and nitric acid. Even with nitric acid concentrations up to 80%, titanium pipes maintain good corrosion resistance at room temperature. In the paper industry, pulp contains various chemical substances; titanium pipes can be used in pulp transport pipelines to resist corrosive components such as sulfides, ensuring long-term stable pipeline operation.

(II) Excellent Mechanical Properties
High Strength-to-Weight Ratio
Titanium tubes possess high strength, with tensile strength ranging from 430 to 1400 MPa, while maintaining a relatively low density of approximately 4.5 g/cm³, only about 60% of that of steel. This makes titanium tubes widely used in the aerospace field. For example, in aircraft hydraulic systems, using titanium tubes can significantly reduce the overall weight of the aircraft while ensuring system strength requirements, thereby reducing fuel consumption and improving flight performance.
Good Toughness and Fatigue Resistance
Titanium tubes exhibit excellent toughness, capable of withstanding large deformations without brittle fracture. Under cyclic loading conditions, such as in heat exchanger pipes in petrochemical plants, titanium tubes demonstrate good fatigue resistance. They can operate for extended periods in environments with frequent temperature changes and pressure fluctuations without easily developing fatigue cracks, thus ensuring the reliability and safety of the equipment.
(IV) High Temperature Resistance
Stability in High-Temperature Environments
Titanium tubes exhibit good thermal stability within a certain temperature range. Pure titanium has a melting point as high as 1668℃, and titanium tubes retain a certain level of strength and toughness even at high temperatures. In certain components of aero engines, such as the cooling channels for compressor blades, titanium tubes can withstand high operating temperatures while maintaining structural integrity, thereby helping to improve engine efficiency and reliability.
