🔍 Product Overview:

The Hastelloy B3 Weld Neck Flange, built to AWWA C207 Class D standards, is designed to provide reliable and secure connections in high-pressure piping systems where corrosion resistance is crucial. With a 2-inch nominal size and a Class D pressure rating, this flange is ideal for applications in chemical processing, water treatment, and marine environments, where corrosion resistance is critical. Manufactured from Hastelloy B3, a high-performance nickel-molybdenum alloy, it offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it perfect for handling aggressive and corrosive substances.

🛡️ Material Advantages – Hastelloy B3:

Superior resistance to corrosion in harsh environments, particularly in chloride-induced and high-temperature conditions

Highly resistant to sulfuric acid, phosphoric acid, and hydrochloric acid, which can severely degrade other materials

Outstanding weldability and fabrication properties, making it ideal for welded piping systems

Enhanced performance in aerospace and chemical processing industries due to its ability to withstand both high temperature and corrosive conditions

⚙️ Flange Features:

Flange Type: Weld Neck Flange (WN Flange) – Designed with a long neck that allows for smooth flow transitions and better alignment in the piping system. This type of flange is well-suited for high-pressure applications and systems with fluctuating temperatures.

Standard: AWWA C207 Class D – Manufactured to American Water Works Association standards, ensuring it meets the demands of water systems and provides reliable sealing in municipal and industrial pipelines.

Size: 2 inches – A compact and standard size for smaller pipeline systems, ideal for applications where space is limited.

Pressure Rating: Class D – Suitable for medium-pressure applications in systems that require a durable seal and ability to handle various environmental stressors.

Material: Hastelloy B3 – A nickel-molybdenum alloy known for its exceptional resistance to aggressive chemicals and corrosion, especially in high-temperature and acidic environments.

Face Type: Raised Face (RF) – Ensures a tight seal when mated with a corresponding flange, providing leak-free operation in high-pressure systems.

🏭 Typical Applications:

Chemical Processing: Ideal for systems that handle aggressive chemicals such as phosphoric acid, hydrochloric acid, and chlorides, where corrosion resistance is crucial.

Water Treatment Plants: Used in water systems that require corrosion-resistant components to prevent degradation from harsh water environments.

Marine Environments: Performs well in seawater and other saltwater applications, protecting the system from corrosion and ensuring long-lasting service.

Power Plants: Suitable for handling high-temperature fluids and providing reliable seals under extreme operational conditions.

Aerospace and Aviation: Perfect for applications in high-temperature environments where corrosion resistance and performance are critical.
