Titanium flange is a pipe connecting component made of titanium or titanium alloy:

1、 Physical and mechanical properties

1. Lightweight and High Strength: With a density of approximately 4.5g/cm ³, it ranks first among metal materials in terms of specific strength, significantly reducing the load on pipeline systems.

2. Excellent temperature resistance

High temperature: Conventional titanium flanges can work for a long time at 300 ℃, while the new titanium alloy is suitable for temperatures up to 600 ℃.

Low temperature: Titanium alloys such as TA7 and TC4 maintain toughness and ductility at -196~253 ℃ without cold brittleness.

3. Low elastic modulus: The elastic modulus is 106.4GPa, and it has stronger elastic deformation ability under stress.

2、 Chemical and Environmental Adaptability

1. Corrosion resistance

A dense oxide film is formed on the surface, which can self repair damage and resist corrosion from seawater, acid, and chloride ions.

Special alloys such as Ti31 have a seawater corrosion resistance rate only 1/10 of 316L stainless steel.

2. Anti crevice corrosion: By optimizing the composition design, the corrosion resistance in sulfide containing environments is significantly improved.

3、 Functional characteristics

1. Non magnetic and non-toxic: Non magnetic, suitable for precision instruments and strong magnetic field environments; Excellent biocompatibility, widely used in medical devices.

2. Anti fatigue and anti damping: Outstanding resistance to alternating loads; Mechanical vibration has a long attenuation time and is suitable for high-precision vibration components.

3. Heat transfer performance optimization: Corrosion resistance allows for a reduction in wall thickness, combined with droplet condensation design to lower thermal resistance and suppress scaling.

4、 Typical application areas

Chemical/Ocean Engineering: Strong corrosive medium pipelines, seawater desalination systems, corrosion resistance;

Aerospace: engine components, rocket structural components, lightweight+high temperature resistance;

Energy: Cooling systems for nuclear power plants, LNG low-temperature valves, low-temperature toughness+radiation resistance.
