Blind Raised Face (BLRF) flanges are round plates that seal the ends of piping systems. These flanges lack a center hole but include all necessary bolt holes. They are commonly used to block pipelines, pumps, and valves, but they can also be used as inspection covers. Their sturdy design makes them ideal for safely sealing pipe ends. Tesco Steel & Engineering is a trusted BLRF flanges manufacturer, providing these flanges in a variety of sizes, grades, and thicknesses to meet industrial specifications.
BLRF flanges are available in sizes ranging from 1/2″ (15 NB) to 48″ (1200 NB). Pressure classes include 150, 300, 600, 900, 1500, and 2500 LBS, along with DIN standards ND-6 to ND-40. Available in surface treatments like anti-rust paint, zinc plating, oil black paint, and hot-dip galvanizing for extended life and protection. These blind flanges are made from materials such as stainless steel, carbon steel, low-temperature carbon steel, alloy steel, copper alloy, duplex and super duplex steel, and nickel alloys. The wide variety ensures you get exactly what your system demands.
These flanges are built for precision and strength. Their solid construction makes them reliable under high pressure and load. Known for smooth operation and long service life, they are cost-effective and easy to install. The design provides easy access to a sealed line, making it useful for maintenance or system changes. BLRF flanges are often machined to accept a nominal size pipe for reductions, either threaded or welded. They can also be fitted with NPT connections for pressure testing when needed.
