Our industrial Forged Flanges are engineered to provide exceptional structural support and leak-proof sealing in high-pressure pipelines, ensuring easy access for cleaning, inspection, and modification.
We supply a massive inventory of flanges across all configurations, including Weld Neck (WNRF) for high-stress applications, Slip-On (SORF) for easy alignment, and Blind Flanges for isolation. Our material expertise spans from Forged Statinless Steel (A105) and Low Temp Steel (LF2) to Austenitic Stainless Steel (304L/316L). For offshore and subsea environments, we offer high-strength Duplex 2205, Super Duplex 2507 (F53/F55), and the hyper-corrosion resistant SMO 254 super austenitic flanges.
All flanges are strictly manufactured in accordance with ASME B16.5, B16.47 Series A & B, and DIN/EN standards. We provide multiple facing options such as Raised Face (RF), Ring Type Joint (RTJ), and Flat Face (FF). Every flange undergoes rigorous ultrasonic testing and dimensional inspection to ensure it withstands extreme thermal expansion and mechanical loads in oil, gas, and power generation sectors.
