Introduction to Titanium-Lined Flanges!

2026,02,05

Titan-lined flanges are flange connectors that combine Titanium Material as an inner lining with base metals such as carbon steel. They integrate titanium's corrosion resistance with carbon steel's high strength and cost-effectiveness, making them suitable for industrial applications in chemical, petrochemical, and pharmaceutical sectors where highly corrosive media exist alongside stringent structural strength requirements.

1. Structural Features and Working Principle

Titan-lined flanges typically consist of a carbon steel flange body with an inner titanium lining layer, generally 1.6–3 mm thick. This thickness effectively resists corrosion from aggressive media like chloride ions and acidic solutions. This design achieves “toughness on the inside, strength on the outside”: the outer carbon steel provides mechanical strength and connection stability, while the inner titanium layer directly contacts the medium, preventing corrosion penetration and extending equipment lifespan.

2. Key Advantages

High Cost-Effectiveness: Compared to solid titanium flanges, the lined structure significantly reduces material costs, making it particularly suitable for large-diameter, high-pressure piping systems.

Exceptional Corrosion Resistance: The titanium lining demonstrates stable performance in environments like hydrochloric acid, chlor-alkali, and seawater, exhibiting extremely low corrosion rates.

Excellent Machinability: Supports customized designs, including various pressure ratings (PN10~PN100), diameters (DN15~DN600), and connection methods (butt welding, slip-on welding, threaded connections).
