Everything You Need to Know About Hastelloy C22/C276 Flanges – Applications, Advantages, and Types

Hastelloy C22 and C276 flanges are critical components used in extreme industrial environments where corrosion resistance, durability, and high performance are essential. At Sandvik, we specialize in providing top-grade Hastelloy flanges engineered to perform under the harshest conditions. Whether you're managing a chemical processing facility or an offshore oil rig, our flanges deliver unmatched reliability and long-term value.

But what exactly are Hastelloy C22/C276 flanges? These are high-alloy components made from nickel-chromium-molybdenum-based superalloys, specifically Hastelloy C22 and Hastelloy C276. They serve as connectors in piping systems, providing secure joins while resisting corrosion and oxidation in aggressive environments. These flanges are widely chosen for their strength, heat resistance, and resistance to a wide range of chemical substances.

One of the standout advantages of using Hastelloy C22/C276 flanges is their superior corrosion resistance. Both grades can withstand oxidizing and reducing agents, which makes them ideal for industries handling toxic and corrosive chemicals. C22 offers better resistance to oxidizing media than C276, while C276 is renowned for its effectiveness in wet chlorine gas, hypochlorite, and chlorine dioxide environments. These alloys also resist stress corrosion cracking and pitting, ensuring a longer service life and reducing maintenance costs.

Hastelloy C22/C276 Flanges Manufacturers like Sandvik understand the importance of precision and performance. That’s why our flanges are produced using advanced manufacturing techniques and strict quality control to ensure they meet global standards. We offer custom machining and dimension flexibility, so your operations don’t have to compromise.

The applications of Hastelloy C22 and C276 flanges span across multiple high-stress industries. In chemical processing, they are used in reactors, heat exchangers, and pressure vessels. In marine and offshore sectors, they prevent seawater corrosion. Power generation plants use them for boiler feedwater systems, while pharmaceutical and food industries rely on them for hygiene and contamination resistance. Their versatility extends to pollution control, paper manufacturing, and waste treatment as well.

Hastelloy C22/C276 Flanges Suppliers play a crucial role in ensuring that clients receive the correct grade and specification for their exact need. At Sandvik, we maintain a robust inventory to meet urgent project timelines and custom requirements swiftly.

Now let’s break down the major types of Hastelloy flanges:

Weld Neck Flanges: Ideal for high-pressure applications, these flanges are welded to the pipe, providing excellent stress distribution and structural integrity.

Socket Weld Flanges: These flanges are best for smaller-diameter, high-pressure pipes. They offer easy alignment and a leak-proof connection.

Slip-On Flanges: Cost-effective and easy to install, they are commonly used in low-pressure and non-critical systems.

Blind Flanges: Used to seal the end of a piping system or vessel opening. Essential for maintenance and inspection.

Lap Joint Flanges: Paired with a stub end, they’re suitable for systems that need frequent dismantling for inspection or cleaning.

Hastelloy C22/C276 Flanges Stockists like Sandvik offer all these variants with detailed specifications, ready for dispatch globally. We ensure optimal compatibility with your existing systems, reducing downtime and installation challenges.
