Stainless Steel 316Ti Instrumentation Tubes are widely recognized for their superior corrosion resistance, high-temperature strength, and reliability in demanding environments. These tubes are specially designed for instrumentation systems that require precise flow control, high performance, and long-term durability. The addition of titanium (Ti) in the 316 stainless steel alloy significantly enhances its resistance to sensitization and intergranular corrosion, especially in high-temperature applications.
What are Stainless Steel 316Ti Instrumentation Tubes?
Stainless Steel 316Ti is a titanium-stabilized version of 316 stainless steel. While 316 contains molybdenum for improved resistance to pitting and crevice corrosion, the inclusion of titanium in 316Ti enhances its resistance to carbide precipitation during welding and prolonged exposure to elevated temperatures (typically above 800°F or 425°C).
Instrumentation tubes made from 316Ti are precision-engineered to meet the requirements of industries like petrochemicals, oil & gas, power generation, pharmaceuticals, and food processing. These tubes are commonly used in measurement and control equipment, chemical injection systems, and hydraulic and pneumatic lines.
Key Features of SS 316Ti Instrumentation Tubes
- High-Temperature Resistance: Titanium stabilization prevents chromium carbide formation, making the tubes suitable for elevated temperature applications.
- Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and general corrosion in chloride-containing environments.
- Weldability: Good weldability without the risk of sensitization, maintaining corrosion resistance after welding.
- Dimensional Accuracy: Manufactured with tight tolerances for precision in flow and pressure control systems.
- Clean Inner Surface: Ideal for high-purity applications where contamination must be minimized.
