Hastelloy C276 Flanges

Jun 01

Hastelloy Flanges have gained popularity as one of the most widely used pipe fittings across industries worldwide. They possess exceptional corrosion resistance and versatility. These flanges consist of a highly durable nickel-molybdenum-chromium alloy, ensuring high resistance to corrosion in virtually any environment. In this blog post, we’ll discuss what Hastelloy C276 Flanges are, their properties, and their use in different applications.

What are Hastelloy C276 Flanges?

Hastelloy flanges connect pipes at various angles and provide a leak-tight connection. They come in different sizes, shapes, and ratings to suit the requirements of other industrial processes. Hastelloy C276 is a Nickel-molybdenum alloy with high chromium content for excellent acid resistance. Ideal for harsh chemical processing plants handling hydrochloric, sulfuric, and phosphoric acids.

Properties of Hastelloy C276 Flanges

Hastelloy flanges are highly resistant to corrosion, even in acidic environments. These flanges can withstand temperatures up to 1,900°F, making them ideal for high-temperature environments. They’re also very durable and can withstand high pressure, making them suitable for pipelines and other industrial applications. Their resistance to chemical corrosion makes them ideal for areas with high chemical concentrations, which would otherwise cause rapid deterioration of the flanges.

Uses of Hastelloy C276 Flanges

Due to their exceptional corrosion resistance, Hastelloy flanges are utilised in various applications such as chemical processing, petrochemicals, power generation, and pulp and paper. These flanges can also be used in offshore drilling systems, pollution control systems, and flue gas scrubbers in coal-fired power plants. Their versatility is enhanced by their corrosion, temperature, and pressure resistance, making them highly adaptable to various industrial processes.

Maintenance of Hastelloy C276 Flanges

To ensure the optimal performance of Hastelloy flanges, it’s important to maintain them frequently. One recommended maintenance procedure is a routine inspection to identify worn-out flanges or damaged components. Another effective approach is using a suitable lubricant to protect from corrosion. Regularly performing an acid cleaning also eliminates any buildup of corrosive deposits.


These flanges are critical components in various industrial systems and significantly impact the efficiency and safety of different industrial processes. These flanges are durable, versatile, and highly resistant to corrosion, making them ideal for harsh environments. Proper maintenance of these flanges ensures excellent performance over the long term. By utilising the benefits of Hastelloy C276 flanges, companies can optimise their processes and minimise the risk of system failure or corrosion-related accidents.
