Hastelloy Flanges Applications and Uses
Hastelloy flanges are used in a wide range of industrial applications, including chemical processing, oil and gas, pharmaceuticals, and power generation. They are commonly used in pipelines, valves, pumps, heat exchangers, and other equipment. Here are some examples of how Hastelloy flanges are used in various industries:
Chemical Processing Chemical processing plants use Hastelloy flanges to connect pipelines, valves, and other equipment that come into contact with highly corrosive chemicals. Hastelloy’s corrosion resistance properties make it ideal for use in this industry. Hastelloy flanges can also withstand high temperatures and pressures, making them suitable for use in distillation columns, reactors, and other high-temperature applications.
Oil and Gas Oil and gas refineries use Hastelloy flanges in pipelines, valves, and other equipment that come into contact with crude oil, natural gas, and other corrosive substances. Hastelloy’s corrosion resistance properties make it ideal for use in this industry. Hastelloy flanges can also withstand high temperatures and pressures, making them suitable for use in boilers, heat exchangers, and other equipment.
Pharmaceuticals Pharmaceutical companies use Hastelloy flanges in equipment used to produce medicines, vaccines, and other medical products. Hastelloy’s corrosion resistance properties make it ideal for use in this industry, where the equipment must be kept sterile and free from contamination. Hastelloy flanges can also withstand high temperatures and pressures, making them suitable for use in sterilization equipment, reactors, and other high-temperature applications.
Power Generation Power plants use Hastelloy flanges in equipment used to generate electricity, such as boilers, heat exchangers, and turbines. Hastelloy’s high-temperature resistance properties make it ideal for use in this industry. Hastelloy flanges can also withstand high pressures, making them suitable for use in pipelines and valves.
