✅ Hastelloy C276 Weld Neck Flange – API 6A – 4" – 10000 PSI

Product Name: Hastelloy C276 Weld Neck Flange
Standard: API 6A
Nominal Size: 4 inches
Pressure Rating: 10000 PSI
Material: Hastelloy C276 (UNS N10276)
Flange Type: Weld Neck Flange (WN Flange)

🔍 Product Overview:

The Hastelloy C276 Weld Neck Flange, produced according to the API 6A standard, is engineered to offer exceptional resistance to a variety of aggressive corrosive environments. Manufactured from Hastelloy C276 (UNS N10276), a nickel-molybdenum-chromium alloy, this 4-inch flange is designed to withstand high pressures of up to 10000 PSI. It is especially suitable for industries that handle high-temperature and high-pressure systems, such as oil & gas, chemical processing, and marine environments.

The Weld Neck Flange design ensures integrity and strength for high-pressure systems by providing a smooth transition from the pipe to the flange, making it ideal for stress-concentrated environments.

🛡️ Material Advantages – Hastelloy C276:

Unmatched corrosion resistance to a wide variety of aggressive media, including sulfuric acid, chlorides, and sea water

Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking

Withstands exposure to oxidizing and reducing environments with temperatures up to 1,800°F (982°C)

Superior weldability and fabrication properties, making it ideal for high-performance and safety-critical applications

Highly resistant to chloride-induced stress corrosion cracking (CISCC)
