Application
Storage Tanks and Pressure Vessels: High silicon-containing stainless steels offer enhanced resistance against concentrated acids, such as sulfuric acid, which is advantageous in storing and processing these chemicals.
Process Piping and Heat Exchangers: The high corrosion resistance of high molybdenum-containing and duplex stainless steels makes them suitable for pipes and heat exchangers in environments where aggressive chemicals are processed.
Offshore Platforms: Duplex stainless steel, known for its high strength and excellent corrosion resistance, is ideal for structural components in harsh marine environments.
Pipelines and Valves: The high strength and corrosion resistance of ASTM A240 steels make them suitable for pipelines that transport corrosive oil and gas mixtures under high pressures.
Flue Gas Desulfurization Systems: High silicon stainless steels in flue gas systems help resist the corrosive effects of sulfur compounds produced during combustion.
Boilers and Components: High-temperature and high molybdenum stainless steels can withstand the corrosive and high-temperature environments in boilers.
Evaporators and Filters: Duplex stainless steels are used in components that require high corrosion resistance and strength to endure the saline and corrosive environment in desalination plants.
Piping Systems: High molybdenum stainless steel’s corrosion resistance to chlorides makes them ideal for piping in water treatment facilities.
Processing Equipment: ASTM A240 stainless steel plate is commonly used in food processing equipment because it maintains purity standards and resists acidic food substances.
Storage Containers: Its non-reactive properties make it suitable for large tanks that store various liquids and processed foods without altering taste or safety.
Reactor Vessels and Fermenters: These steels’ cleanability and corrosion resistance are crucial in environments where sterility and resistance to various chemicals are necessary.
Piping and Ductwork: Ensures purity and resistance to corrosive cleaning agents.
