Weld Neck Flange (WNRF)

Weld Neck Flanges supplied by Anchor Building Materials Trading LLC are engineered for the most demanding industrial piping systems. Featuring a long tapered hub and butt‑weld connection, these flanges provide superior structural integrity, reduced stress concentration, and exceptional performance under high pressure and high temperature.

Manufactured according to ANSI/ASME B16.5, B16.47, DIN, and API standards, Weld Neck Flanges are widely used in oil & gas pipelines, petrochemical plants, refineries, power generation systems, and critical industrial applications. Their robust design ensures leak‑free operation, excellent fatigue resistance, and long‑term durability in UAE’s harsh industrial environments.

Available in raised face (RF), ring‑type joint (RTJ), and flat face (FF) configurations, Weld Neck Flanges are suitable for a wide range of pressure classes and piping materials.
