Butt Welded Flange 1 Pressure Vessel Flange series butt-welding flange

A neck butt-welding flange has a cone-shaped neck welded to a pipe or cylinder. It's a strong, one-piece flange that seals better than flat weld flanges. It's suitable for high-pressure, temperature, or strict sealing needs.

A neck butt-welding flange has a cone-shaped neck welded to a pipe or cylinder. It’s a strong, one-piece flange that seals better than flat weld flanges. 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).
