Product Q&A

Q:What are the common applications for Weld Neck Flanges?

They are ideal for critical high-pressure, high-temperature, and high-vibration applications in oil & gas, power generation, petrochemical, and marine industries.

Q:What materials are available for these flanges?

Materials include Carbon Steel (A105, Q235B), Stainless Steel (304/316), Alloy Steel (F11/F22), and Duplex Stainless Steel (2205/2507).

Q:What sealing face types are supported?

Common types include Raised Face (RF), Ring Joint Face (RJ), Tongue-and-Groove (TG), and Male-Female (MFM).

Q:Which international standards are followed?

Manufacturing follows ANSI B16.5, ANSI B16.47, DIN EN 1092-1, BS 4504, and GB/T 9115 standards.

Q:How does the design improve pipeline performance?

The tapered hub eliminates stress concentration and reduces pressure drop by minimizing turbulence during fluid flow.
