Weld Neck Flanges Pressure Vessel Flange Series

Weld Neck Flanges Pressure Vessel Flange series

The weld neck flange (WN) is a highly versatile and widely utilized flange type, designed with a long, tapered hub that ensures a robust and seamless connection to pipes.

Ideal for high-pressure and extreme temperature applications, this flange provides an unrestricted flow of fluids through the piping system.

The bore of the weld neck flange aligns with the pipe bore, allowing for a smooth and efficient passage of gases or liquids.

Weld Neck Flange has a cone-shaped neck welded to a pipe or cylinder. It’s a strong, one-piece flange that seals better than slip on flange. But it uses more materials and costs more to make because it needs forging. It’s suitable for high-pressure, temperature, or strict sealing needs.

Why Choose Our Weld Neck Flange?

• Robust and Secure Connection: The cone-shaped neck provides a strong, seamless connection that enhances sealing and reliability, especially in high-pressure and high-temperature environments.
• Versatile Application: Suitable for extreme conditions, ensures unrestricted fluid flow, making it ideal for demanding applications where performance is critical.
• Aligned Bore for Efficiency: The bore of the flange aligns with the pipe bore, facilitating smooth and efficient passage of gases or liquids, reducing turbulence and improving system efficiency.
• High-Quality Materials: Available in 304, 304L, 316L stainless steels, and high-strength alloys like 2507 and 2205, ensuring durability and suitability for various operational needs.
• Compliance with Standards: Manufactured to meet rigorous standards (GB/T9119-2010, HG/T20592-2009, DIN, ASME, BS, JIS).
