FI80 Heavy Duty Internal Flange Facer: The Large-Scale Machining Powerhouse

The FI80 is a premier, bore-mounted flange facing system engineered for the precision in-situ restoration of extra-large industrial flanges. With a massive machining envelope of 26.34" to 80" (670-2032 mm), this heavy-duty unit is the industry standard for projects requiring absolute flatness and structural rigidity across large surface areas.

From offshore energy hubs to massive petrochemical reactors, the FI80 is designed to return worn, pitted, or warped sealing faces to ASME B16.5 factory specifications. Its reinforced modular frame and high-torque drive system ensure that even the largest flanges can be machined with workshop-level accuracy directly in the field.

Key Features and Advantages

Massive Diameter Versatility: A single-platform solution covering 26" to 80" diameters, eliminating the need for multiple machines on complex, large-scale maintenance sites.
Multi-Profile Precision: Engineered to machine Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ) grooves, and custom chamfers or V-grooves with repeatable accuracy.
Advanced Guidance System: Features a specialized heavy-duty "V" linear guide and premium NSK bearings, providing the vibration-free stability necessary for large-diameter cutting.
Dual-Drive Performance: FI80P (Pneumatic): High-output air motor for safe operation in ATEX-restricted or hazardous gas zones. FI80E (Electric Servo): Precision-controlled servo drive for consistent torque and ultra-fine surface finishes in stable power environments.
Superior Sealing Finish: Produces the high-integrity phonographic (spiral serrated) finish essential for long-term gasket reliability and leak prevention.
