FI26 Portable Internal Flange Facer: 120-700 mm Facing Diameter with Pneumatic / Electric Servo Drive and ID-Mounted Design

The FI26 is a robust, bore-mounted flange facing machine engineered to deliver workshop-grade accuracy for on-site mid-to-large diameter machining. Specially designed for confined spaces and critical plant turnarounds, it covers an extensive machining envelope from 120 to 700 mm (4.72"-27.56").

This high-performance field tool is built to re-machine warped, eroded, or leaking sealing faces back to stringent ASME B16.5 standards. By locking securely inside the pipe bore, the FI26 provides a rigid, vibration-free cutting platform that eliminates the need for costly asset dismantling, allowing teams to service flanges in horizontal, vertical, or overhead positions.

• Comprehensive Profile Versatility: Seamlessly restores Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ) grooves, Tongue & Groove (T&G), lens rings, and custom sealing profiles.
• Dual-Drive Adaptability: FI26P: Driven by a spark-free air motor, engineered for safe operation in ATEX-regulated or hazardous petrochemical environments. FI26E: Outfitted with a digital servo motor for constant torque and micro-controlled speed stability during fine finishing passes.
• Pre-Loaded Alignment Components: Equipped with premium NSK precision bearings paired with hardened linear guideways to resist structural deflection and tool chatter.
• Two-Speed Mechanical Feed System: Offers automated radial feed rates of 0.125 mm/rev and 0.5 mm/rev, allowing operators to toggle effortlessly between smooth finishes and the precise phonographic (spiral-grooved) surface required for gas-tight gasket seating.
• Multi-Angle Tooling Head: The tool post features a full 360-degree swivel mechanism, allowing technicians to execute complex internal counterboring, angled chamfers, and detailed profile grooves.
• Rapid Centering Mounting System: Three interchangeable internal mounting bases with micro-adjusting chuck jaws ensure quick centering, secure clamping, and repeatable setup across varying bore sizes.

• Oil & Gas Pipeline Maintenance: In-situ repair of mid-bore pipeline joints and transport manifolds.
• Refinery & Petrochemical Turnarounds: Re-machining aggressive-media pipeline connections and pressure vessel nozzles.
• Power Generation Facilities: Maintenance of critical steam lines and cooling system connections in thermal, hydro, and nuclear plants.
• Offshore & Marine Engineering: Corrosive-environment servicing of topside piping, FPSO systems, and subsea tie-ins.
• Fabrication Workshops: Precision flange face preparation and custom groove cutting before installation.
