3. Application Of GOST33259 Titanium Flange Titanium Ring:
Chemical industry: Titanium flanges are widely used in chemical factories, petroleum refineries, pharmaceutical factories and other chemical fields. Due to the excellent corrosion resistance of titanium materials, it can withstand strong corrosive media such as acids and alkalis, salts and organic solvents, so it is used to connect pipes, containers and equipment.
Marine engineering: The marine environment is extremely corrosive to metal materials, and titanium has excellent seawater corrosion resistance, so titanium flanges are widely used in marine engineering such as offshore platforms, ships, and submarine pipelines.
Aerospace industry: Due to the high strength and low density of titanium materials, titanium flanges are widely used in aerospace fields, such as aircraft engines, gas turbines, aerospace equipment, etc.
Oil and natural gas industry: High pressure and corrosive media are often encountered in the process of oil and natural gas extraction, transportation and storage. Titanium flanges can meet the requirements under these harsh conditions and are used to connect pipelines, valves and storage tanks.
Medical field: Titanium has good biocompatibility and corrosion resistance, so it is widely used in medical devices such as medical equipment and artificial joints. Titanium flanges are used to connect and support piping systems for medical equipment.
