Hastelloy C22 Round Bar Application
The Hastelloy C22 round bars manufactured by us play a vital part in a great many industrial fields. They have a lot of excellent properties and have a wide range of application scenarios. Let’s take a look together.
- Chemical and Petrochemical Fields：Hastelloy C22 round bars are often used to manufacture key chemical equipment such as chemical reactors, heat exchangers, storage tanks and pipelines. Since various corrosive media like strong acids, alkalis and salts will be encountered during the chemical processing, Hastelloy C22 round bars are able to keep stable performance in tough corrosive conditions, guaranteeing the safe and effective progress of chemical production.
- In the Oil and Gas Industry: The corrosion resistance of Hastelloy C22 round bars enables them to operate stably for a long time under acidic conditions. They are often used in equipment for oil and gas exploration, processing, and transportation in high-temperature and high-pressure environments.
- Seawater Cooling Facilities and Marine Engineering: As seawater contains a large amount of chloride ions and has extremely strong corrosiveness, Hastelloy C22 round bars are often used in seawater cooling equipment, subsea pipelines, and marine vessel equipment.
- Environmental Protection and Wastewater Treatment: Hastelloy C22 round bars are widely used in environmental protection devices such as flue gas desulfurization equipment. They can effectively resist the corrosion of strongly acidic gases. It is also commonly used in wastewater treatment equipment, such as desulfurization towers and denitrification towers.
