Shawn Flanges, located in Houston, USA, has made a name for itself as a leading manufacturer and supplier of BLRF (Blind Raised Face) Flanges. These flanges are celebrated for their exceptional performance in pressure-retaining applications where it’s crucial to seal off pipeline ends. With a raised face design, they ensure a secure fit for gaskets, providing a tight seal. Shawn Flanges offers these flanges in a variety of materials, including carbon steel, stainless steel, alloy steel, and exotic alloys, all crafted to meet ANSI, ASME, DIN, and EN standards. They’re widely utilized across sectors like oil & gas, petrochemicals, water treatment, and power generation, where high-integrity systems are essential.
BLRF Flanges from Shawn Flanges are crafted from a selection of materials, including ASTM A105 (carbon steel), ASTM A182 F304/F316 (stainless steel), and A694 F52–F70 (high-yield alloys). While the mechanical properties can differ by grade, they generally provide impressive tensile strength ranging from 485 to 750 MPa and yield strength from 250 to 600 MPa, along with excellent impact resistance and pressure containment. The raised face design not only enhances gasket compression but also boosts sealing effectiveness, even under varying pressure and temperature conditions. These flanges come in multiple pressure classes, from 150 to 2500, catering to a wide array of industrial needs.
