Application
Chemical Processing: Titanium pipe fittings are widely used in chemical processing industries due to their excellent corrosion resistance against various corrosive chemicals. They are used in pipelines, reactors, and other equipment handling corrosive substances.
Marine: Titanium’s resistance to corrosion in saltwater makes it suitable for marine applications. Titanium pipe fittings are used in shipbuilding for seawater cooling, piping, and other marine equipment.
Oil and Gas: Titanium pipe fittings are utilized in offshore platforms, subsea pipelines, and processing equipment in the oil and gas industry due to their resistance to corrosive environments and high strength-to-weight ratio.
Power Generation: Titanium pipe fittings are used in power plants, especially in environments exposed to high temperatures and corrosive gases. They are employed in heat exchangers, condensers, and other components.
Desalination: Titanium’s corrosion resistance and ability to withstand high temperatures make it suitable for desalination plants. In desalination processes, titanium pipe fittings are used to construct evaporators, condensers, and piping systems.
Chemical and Petrochemical: Titanium pipe fittings are used in chemical and petrochemical plants to handle corrosive chemicals, acids, and alkalis. They are employed in pipelines, reactors, and other process equipment.
