1. Excellent corrosion resistance: titanium has strong resistance to seawater, chloride ions, etc,
far superior to stainless steel and carbon steel.
2. No rusting risk: titanium can be used long-term without coatings or cathodic protection,
suitable for corrosive environments such as marine and chemical industries.
3. High strength and lightweight: titanium's strength is close to steel, but its density is only 60% of steel,
which significantly reduces the weight, makes it suitable for aerospace, shipbuilding and other fields.
4. Low temperature performance: titanium flange can maintain toughness even in ultra-low temperatures
(such as in liquid nitrogen and liquid oxygen environments), suitable for low-temperature engineering.
5. Excellent heat resistance: titanium flanges can maintain mechanical properties (such as TA2, TA9 and
other alloys) at 300-500°C, with short-term tolerance to even higher temperatures.
6. Oxidation resistance: titanium will form a dense oxide film on the surface at high temperatures,
preventing further oxidation.
7. Long lifespan and low maintenance cost durability: lifespan can exceed that of stainless steel by
over ten times in corrosive environments.
8. Economic efficiency: although titanium flange costs are higher initially, but it costs over the entire
lifecycle are lower.
9. Biocompatibility non-toxic and harmless: suitable for industries such as pharmaceuticals and food
processing, which require high material purity.
10. Good machinability and joint performance weldability: titanium flange can be welded using methods
such as TIG and plasma welding, providing high weld strength, they can be designed for flat welding,
butt welding, threaded types, etc., to meet the needs of different piping systems.
