Application

Chemical Processing: Titanium torispherical heads are ideal for vessels in chemical plants that process highly corrosive substances like acids, alkalis, and other harsh chemicals without degradation.
Oil and Gas Production: Used in separators, pressure vessels, and storage tanks, resistance to corrosion by saltwater and hydrocarbons makes it particularly suited for offshore platforms and onshore refineries.
Pharmaceutical Manufacturing: The non-reactive nature of titanium makes these heads suitable for bioreactors and storage tanks in pharmaceutical production.
Desalination Plants: Titanium torispherical heads are used in the high-pressure vessels of desalination plants, where seawater’s corrosive nature can severely limit the lifespan of less durable materials.
Power Generation: Especially in nuclear power plants, the strength and corrosion resistance of titanium are critical for containing and managing radioactive materials safely.
