The performance characteristics of titanium fittings!


Excellent corrosion resistance

Titanium fittings perform well in various corrosive environments. This is because titanium can quickly form a dense and stable oxide film (TiO ₂) in air or oxidizing media, which can prevent further contact between corrosive media and the titanium substrate, playing a self-protection role. For example, in the chemical industry, titanium fittings can resist the erosion of strong acids such as concentrated sulfuric acid and nitric acid, as well as highly corrosive media such as seawater and brine, and can transport corrosive fluids stably for a long time, reducing the maintenance and replacement frequency of pipeline systems.

High strength and good toughness

Titanium pipe fittings have high strength, and their tensile strength can reach 300-1000MPa or more depending on different titanium material grades and processing techniques. At the same time, it also has good toughness and can withstand a certain degree of pressure, impact, and vibration without easily breaking. This combination of strength and toughness enables titanium fittings to have reliable performance when subjected to internal fluid pressure and external environmental forces, such as in high-pressure chemical pipeline systems and marine engineering applications.

High temperature and low temperature resistance performance

The melting point of titanium is relatively high (around 1668 ℃), and titanium pipes can maintain good performance within a certain temperature range. In high temperature environments, although its strength decreases with increasing temperature, it can still maintain a certain degree of structural integrity and strength at relatively high temperatures (such as 300-400 ℃), and can be used in some heat exchange systems in medium temperature environments. In addition, titanium fittings also have good performance in low-temperature environments. For example, in low-temperature pipeline systems such as liquid natural gas (LNG) transportation, titanium fittings can avoid cold brittleness and ensure the safe operation of pipelines.

Good biocompatibility

Titanium fittings have important applications in the medical field, thanks to their excellent biocompatibility. The human body has a minimal rejection reaction to titanium, so titanium fittings can be used in medical pipeline systems, such as artificial blood vessels and dialysis equipment. They can interact well with human tissues and body fluids without causing adverse reactions such as inflammation.

Lightweight

The density of titanium is about 4.51g/cm ³, and compared to other commonly used metal fittings such as iron fittings and copper fittings, titanium fittings are lighter in weight. When applied in aerospace, automotive and other fields, it can effectively reduce the overall weight of pipeline systems, thereby improving energy efficiency or vehicle handling performance. For example, using titanium fittings in the fuel delivery system and hydraulic system of an aircraft can reduce its own weight and fuel consumption.
