Diving equipment: High pressure vessels and connections for use in deep sea environments.
Electronics
Heating Elements: Inconel strip is used to make resistance heaters and electric filaments that maintain performance at high temperatures.
Thermocouples: Sensors used for temperature measurement and control that provide accurate readings at extreme temperatures.
Micro Electro Mechanical Systems (MEMS): Inconel strips are used to manufacture miniature mechanical components that require high strength and stability at high temperatures.
Oil and Gas
Downhole equipment: such as drill pipe, casing and wellhead equipment, Inconel strip is capable of working in high-pressure, high-temperature and corrosive environments.
Natural gas processing equipment: such as desulphurisation units and heat exchangers, handling fluids containing hydrogen sulphide and other corrosive gases.
Offshore mining equipment, such as components of floating production storage and offloading units (FPSOs), which are exposed to the marine environment for long periods of time.
The outstanding properties of Inconel strip make it an indispensable material in these areas, ensuring the reliability and longevity of equipment and systems under extreme conditions.
