FI26 Flange Facer – Portable ID-Mounted Flange Facing Machine for On-Site Repair (120–700 mm)
FI26 Internally Mounted Flange Facer
Portable ID-Mounted Flange Facing Machine for On-Site Repair (120-700 mm)
Product Overview
The FI26 Internally Mounted Flange Facer is a robust and high-accuracy portable flange facing machine developed for on-site flange resurfacing, sealing face correction, and groove restoration. Designed to mount securely inside the flange bore, the FI26 covers a wide machining range from 120 to 700 mm (4.72"-27.56"), making it suitable for both medium and large-diameter flanges.
This ID-mounted flange facing machine is engineered to restore flat face (FF), raised face (RF), ring type joint (RTJ), tongue and groove (T&G), lens ring, and special sealing profiles, ensuring surface finishes compliant with ASME B16.5 requirements. Its rigid construction, precision bearing system, and flexible drive configurations make the FI26 a reliable solution for demanding field maintenance in oil & gas, petrochemical, power generation, marine, and offshore industries.
Key Advantages
ID-Mounted, Field-Ready Design
The internal mounting system provides stable, vibration-free clamping, allowing safe and accurate machining in horizontal, vertical, or overhead positions—ideal for confined job sites.
High Machining Accuracy
Equipped with NSK high-precision bearings and linear guideways, the FI26 maintains excellent rigidity, ensuring consistent cutting accuracy and superior surface finish quality.
Dual Feed Rate System
Selectable feed speeds of 0.125 mm/rev and 0.5 mm/rev enable both smooth finishes and phonographic spiral serrations to meet standard sealing specifications.
Wide Flange Application Range
Capable of machining FF, RF, RTJ, T&G, compact flanges, lens ring grooves, and customized sealing geometries.
Adjustable Mounting Bases
Three interchangeable ID-mount bases with micro-adjustable jaws ensure fast centering and easy alignment across various bore sizes.
360° Swivel Tool Post
Allows multi-angle cutting operations, complex groove machining, and improved flexibility for different flange standards.
Built for Harsh Environments
Designed for long-term use in offshore platforms, refineries, chemical plants, and power stations, even under demanding site conditions.
