Deep sea oil and gas engineering: guardians of pressure and corrosion resistance
In the field of deep-sea oil and gas engineering, titanium rings have demonstrated strong compressive and corrosion resistance, becoming a key component to ensure the safety and efficiency of underwater oil and gas extraction.
Subsea pipeline connection system
In the subsea pipeline connection system, TC4 titanium rings serve as flange seals and play a crucial sealing role. In extreme environments with a water depth of 1000 meters, it has to withstand pressures of up to 10 MPa to ensure that the pipeline connections do not leak. In the ultra deep scenario of tens of thousands of meters, the

Accurate oil circuit control is crucial for stable flight of aircraft in flight control hydraulic systems, and the high-precision performance of titanium alloy servo valve rings provides strong support for flight safety.
Automotive Manufacturing Upgrade: Representations of Lightweight and High Performance
With the development of the automotive industry, lightweight and high-performance have become important goals in automotive manufacturing, and the application of titanium rings in the automotive field precisely meets this demand.
Lightweight powertrain system
The titanium ring housing of the turbocharger replaces traditional cast iron parts, which can reduce weight by 40%, greatly reducing the weight of the car and improving fuel economy. At the same time, it can withstand exhaust gas corrosion temperatures up to 950 ℃, ensuring long-term stable use in high-temperature exhaust gas environments. The TC4 titanium alloy connecting ring of the transmission shaft has achieved zero failure after 100000 cycles of torsional fatigue, with a specific strength of 29, improving the reliability and service life of the transmission system.
Application of new energy vehicles
In hydrogen energy storage tanks, the titanium ring head is formed using ultra plastic forming technology, which can reduce the wall thickness to 3mm, but still maintain a pressure bearing capacity of 70MPa.
