What Are Hastelloy Fittings?
Hastelloy Fittings are pipe connection components made from a corrosion-resistant metal alloy known as Hastelloy. This material contains elements like nickel, molybdenum, iron, and chromium, making it ideal for high-stress and highly corrosive environments. These fittings are perfect for industries that deal with strong chemicals, high heat, and high pressure. Thanks to their strength and durability, Hastelloy Pipe Fittings offer long-lasting performance and safety.
Grades of Hastelloy We Supply
We offer Hastelloy Fittings in different grades to suit various applications:
- Hastelloy C22: Great resistance to oxidizing and reducing chemicals. Used in acid processing and waste treatment.
- Hastelloy C276: Highly resistant to seawater, strong oxidizers, and high temperatures.
- Hastelloy B2: Best for handling hydrochloric acid and other reducing chemicals.
Each grade has its unique benefits. Our experts can help you choose the right one based on your industry and environment.
Types of Hastelloy Fittings We Offer
At Solitaire Fittings, we offer a wide variety of Hastelloy Fittings to suit your project needs:
➤ Hastelloy Pipe Fittings
Our Hastelloy Pipe Fittings are used to connect sections of pipe in systems that require resistance to heat and corrosion. They are commonly used in chemical plants and marine environments.
Common types include:
- Elbows (90° and 45°)
- Tees (equal and reducing)
- Reducers (concentric and eccentric)
- Caps
- Stub Ends
These fittings are ideal for carrying corrosive fluids without the risk of leaks or damage.
➤ Hastelloy Buttweld Fittings
Hastelloy Buttweld Fittings are welded directly to the pipes, creating a strong and smooth connection. These are best for systems that need a permanent, leak-proof setup.
Key advantages:
- Smooth interior surface for better flow
- Strong, long-lasting joints
- Ideal for high-pressure systems
We provide Hastelloy Seamless Buttweld Fittings that offer an even higher level of strength and reliability, with no welds or weak spots.
➤ Hastelloy Forged Fittings
Hastelloy Forged Fittings are made by shaping Hastelloy under high pressure and heat. This process increases the strength and durability of the fittings.
Types we offer:
- Elbows (socket weld and threaded)
- Tees
- Couplings
- Crosses
- Unions
These fittings are commonly used in small-diameter piping systems and can handle high pressure with ease.
➤ Hastelloy Threaded Fittings
Hastelloy Threaded Fittings are screwed onto the pipe ends, making them easy to install and remove. They're ideal for low-pressure systems and places where welding isn’t possible.
Uses include:
- Plumbing systems
- Cooling systems
- Low-pressure chemical lines
They come in a variety of shapes and sizes to match your specific needs.
