High-hub flanges designed to transfer stress to the pipe, reducing stress concentration at the flange bottom. Primarily used in pressure vessel construction as nozzles, eliminating additional welding requirements and providing integral reinforcement.
Features a reducing diameter neck for welding to smaller diameter pipes. Ideal for space-constrained installations, these flanges effectively reduce pipeline diameter without requiring additional reducer fittings.
Maximum allowable working gauge pressures (psi) at various temperatures (°F) according to ASME B16.5 and ASME B16.47 standards. Available in multiple pressure classes from 75 to 2500, with temperature ranges from -20°F to 1200°F.
Our flanges undergo comprehensive manufacturing processes including forging, machining, and quality testing to ensure dimensional accuracy and material integrity for demanding industrial applications.
