A dense TiO₂ oxide film, 2 to 10 nm in thickness, forms on the surface of titanium, enabling the material to withstand corrosion from condensates containing sulfur and nitrogen oxides.
The operating temperature range for titanium exhaust piping spans from -250°C to 600°C (for long-term exposure). It retains exceptional mechanical strength even at high temperatures between 500°C and 600°C, with an instantaneous temperature tolerance of up to 800°C. This ensures that critical components within the exhaust system maintain their structural integrity, dimensional stability, and oxidation resistance under high-temperature conditions.
Customized Services
- Based on exhaust system design drawings, we can precisely customize outer diameter, wall thickness, and length dimensions, maintaining a dimensional tolerance within ±0.05 mm.
- Depending on the client's specific operating conditions, we offer a wide range of material grades, including Grade 1, Grade 2/2H, Grade 3, Grade 4, Grade 5, Grade 7/7H, Grade 9, Grade 10, Grade 11, Grade 12, Grade 13, Grade 14, Grade 15, Grade 16/16H, Grade 26/26H, Grade 27, Grade 28, and Grade 29.
- We support various surface treatments, such as matte sandblasting, mirror polishing (Ra ≤ 0.4 μm), and heavy-layer acid pickling and passivation combined with anti-oxidation coating.
- We provide precision cutting services to create custom geometric shapes for automotive exhaust systems.

Possible Alternative Grades
- Grade 5 (Ti-6Al-4V): Offers superior strength, making it suitable for exhaust systems where ultimate performance is paramount; however, it entails higher costs and presents greater machining challenges.
- Grade 9: Combines excellent strength with good weldability, making it suitable for structural components within exhaust systems.
- Grade 1: Possesses optimal formability and corrosion resistance, making it the ideal choice for components subject to lower stress levels that require complex bending and forming processes.
application areas

FAQ
Q: Is titanium tubing easy to weld?
A: Our titanium tubing has excellent weldability, and its surface undergoes rigorous treatment, removing oil and oxide scale, reducing welding difficulty. TIG welding is recommended; the welded joint strength can reach over 95% of the base material.
Q: Can the strength of our titanium alloy exhaust pipes meet the vibration requirements of a car chassis?
A: Our tubing has passed mechanical performance testing and possesses excellent toughness and deformation resistance, enabling stable operation under conditions of car chassis vibration and road bumps.
Q: Can you provide custom sizes?
A: Yes, we offer non-standard custom services. In addition to dimensions, we can provide bends, reducers, dual exhaust pipes, and other irregular structures according to customer needs.
