Blind Flanges supplied by Anchor Building Materials Trading LLC are engineered for secure pipeline isolation in high‑pressure and high‑temperature systems. Designed without a bore, these flanges completely seal the end of a piping system or pressure vessel opening, making them essential for shutdowns, testing, maintenance, and system modifications.
Manufactured according to ANSI/ASME B16.5, B16.47, DIN, and API standards, Blind Flanges deliver exceptional strength, corrosion resistance, and long‑term reliability. They are widely used in oil & gas facilities, petrochemical plants, power stations, water treatment systems, and industrial processing units across the UAE.
Their robust construction and precision machining ensure leak‑free sealing, even under extreme operating conditions. Blind Flanges are available in raised face (RF), flat face (FF), and ring‑type joint (RTJ) configurations to suit various pressure classes and flange connections.
