When industries operate in extremely corrosive, high-temperature, or chemically aggressive environments, ordinary pipe fittings fail quickly. This is where ASTM B366 Hastelloy C22 Buttweld Fittings stand out. Designed for unmatched corrosion resistance and long service life, these fittings are trusted across critical industries worldwide.
We manufacture and supply a complete range of Hastelloy C22 Pipe Fittings that meet international quality standards and demanding industrial applications. Our fittings are known for precision, strength, and reliability, even in the harshest service conditions.
What Are ASTM B366 Hastelloy C22 Buttweld Fittings?
ASTM B366 UNS N06022 Hastelloy C22 ButtWeld Fittings are high-performance nickel-chromium- molybdenum alloy fittings used to connect pipes through butt welding. These fittings are produced according to ASTM B366 / ASME SB 366 specifications, ensuring uniform dimensions, excellent weldability, and superior mechanical properties.
Hastelloy Alloy C22 (Werkstoff Nr. 2.4602) is one of the most corrosion-resistant alloys available today. It offers outstanding protection against:
- Pitting corrosion
- Crevice corrosion
- Stress corrosion cracking
- Oxidizing and reducing chemicals
Because of this, Hastelloy Alloy C22 Butt Welding Fittings are widely used in chemical processing, pollution control, marine, and pharmaceutical industries.
Why Choose Hastelloy C22 Pipe Fittings?
From our hands-on manufacturing and supply experience, we’ve seen Hastelloy C22 outperform many other nickel alloys in real-world conditions. Some key advantages include:
- Excellent resistance to chlorides and halides
- High strength at elevated temperatures
- Superior weldability without post-weld heat treatment
- Long operational life with minimal maintenance
- Reliable performance in both oxidizing and reducing environments
This makes Hastelloy C22 grade buttweld pipe fittings a preferred choice for engineers and plant designers.
