Hastelloy C22 Flanges

Jul 29

If you’re in an industry that requires high levels of heat, corrosion and chemical resistance, then hastelloy c22 flanges are an excellent option. Hastelloy c22 is an alloy containing nickel, molybdenum, chromium, and tungsten, making it highly resistant to corrosion and other chemical degradation. This blog post dives into everything you need about hastelloy flanges, including their features, benefits, and applications.

What are Hastelloy C22 Flanges?

Hastelloy flanges are an alloy of nickel, molybdenum, chromium and tungsten. It offers superb corrosion resistance properties in a wide range of media. In addition to excellent weldability and good formability characteristics, these flanges provide superior levels of mechanical strength. This makes them a sought-after choice for high-pressure applications such as water desalination systems, petrochemical equipment and pipelines.


This flanges are known for their excellent resistance to oxidizing and reducing environments. They also highly resist stress-corrosion cracking, pitting, and crevice corrosion. Also, hastelloy c22 flanges can withstand temperatures up to 1250°C, making them an ideal choice for high-temperature applications. They also resist sulfuric acid, hydrochloric acid, and other harsh chemicals. Due to these properties, hastelloy flanges are highly sought after in chemical processing, pharmaceuticals, and waste management industries.


Because hastelloy flanges offer exceptional resistance to corrosion and high temperatures, they offer many benefits. For example, they’re long-lasting and require minimal maintenance, making them ideal for harsh environments with frequent wear and tear. Also, hastelloy flanges are extremely versatile, and compatible with many other alloys, gaskets, and fittings. They also offer excellent sealing performance, which minimizes the risk of leaks or spills. Finally, hastelloy c22 flanges are cost-effective, as their long lifespan requires replacement less frequently than other materials.


These are used in a wide range of industrial applications. One of the primary uses for c22 Hastelloy flanges is in chemical processing, transporting harsh chemicals safely and efficiently. They’re also used in the pharmaceutical industry, where they’re used to manufacture medicines and other treatments. Also, flanges are essential in the waste management industry, which stores and transports hazardous materials. Other applications for hastelloy flanges include oil and gas production, food and beverage processing, and pulp and paper manufacturing.

Choosing the Right Hastelloy Flanges

When choosing hastelloy flanges, it’s essential to consider a few key factors. First, you need to determine the size and pressure rating of the flanges you need. It’s also essential to consider the temperature and chemical environment to which the flanges will be exposed, as this will affect the type of gaskets and fittings you’ll need. Additionally, it’s crucial to choose a reputable supplier who can provide high-quality hastelloy c22 flanges that meet industry standards.


In conclusion, hastelloy c22 flanges are an excellent choice for industries requiring high heat, corrosion, and chemical resistance. They offer many benefits, including long-lasting durability, versatile compatibility, excellent sealing performance, and cost-effectiveness. By understanding the features, benefits, and applications of hastelloy c22 flanges, you can choose the right flanges for your specific needs and ensure that they provide optimal performance.
