FI80 Portable ID-Mounted Tool for 26″ to 80″ Flange Refacing
The FI80 Flange Facing Machine is a heavy-duty, internally mounted solution engineered for on-site machining and repair of large-diameter flanges. With a working range from 26.34" to 80" (670–2032 mm), it is the go-to choice for field operations requiring precision, portability, and high-performance flange resurfacing.
Built for challenging industrial environments, the FI80 delivers ASME B16.5-compliant surface finishes on flat face (FF), raised face (RF), ring-type joint (RTJ), V-groove, and specialty sealing surfaces. Its precision NSK bearings, rigid body frame, and V-guide linear slide system ensure smooth, vibration-free cuts — even on oversized flanges.
Available in two drive configurations—pneumatic (FI80P) and electric servo (FI80E)—this flange facing machine adapts easily to various job site power conditions. Its modular mounting system enables fast alignment inside the pipe bore, minimizing downtime and maximizing productivity.
Designed for the oil & gas, chemical, power generation, and offshore industries, the FI80 comes packaged in a rugged waterproof transport crate, ensuring durability and portability across remote or harsh locations.

INDUSTRIES AND APPLICATIONS
The FI80 Flange Facing Machine is purpose-built for large-diameter flange machining tasks across a diverse range of industrial sectors. With its rugged design, internal mounting capability, and ability to handle extreme field conditions, the FI80 delivers consistent, high-precision performance in on-site and workshop environments alike.
Oil and Gas Industry
In the oil and gas sector, the FI80 is widely used for resurfacing flanges on high-pressure pipelines, separators, valve stations, and compressor systems. It is especially suited for offshore platforms and refineries where RTJ and RF flanges must be machined to ASME B16.5 standards. Whether during scheduled maintenance or emergency shutdowns, the machine ensures safe, leak-free sealing through precise flange refacing.
Power Generation
The FI80 plays a vital role in both conventional and nuclear power plants. It is employed to restore sealing surfaces on turbine flanges, steam generator connections, condensers, boilers, and other pressure boundary components. By ensuring a consistent surface finish and flatness, it supports safe plant operation and reduces downtime during outages.
Petrochemical and Chemical Plants
In highly corrosive chemical environments, flange integrity is critical. The FI80 provides accurate and repeatable machining for large-diameter flanges in distillation columns, pressure vessels, storage tanks, and reactors. Its robust structure and finish control help prevent leaks and ensure safety in high-risk process lines.
Shipbuilding and Marine Engineering
From engine room piping to ballast and seawater systems, the FI80 is ideal for large-vessel flange repair and refacing. Its modular design allows it to be used in tight engine compartments or on deck. It also supports repair operations aboard FPSOs, tankers, and offshore drilling platforms, both during drydock overhauls and afloat maintenance.
Mining and Heavy Industry
In mining, cement, and bulk material industries, the FI80 is used to resurface worn or damaged flanges on slurry pipelines, high-pressure pumps, thickener tanks, and heavy-duty processing lines. Its portability allows for field machining in remote, rugged locations where downtime is costly.
Pipeline Construction and Fabrication
The FI80 is a go-to solution for flange preparation in prefabrication shops and on construction sites. It delivers high-precision finishes on flange faces before final welding or bolting, helping reduce rework and ensure perfect gasket contact in critical joints.
Emergency Field Repair Services
For mobile machining crews or on-call maintenance providers, the FI80 supports rapid deployment to restore flange surfaces during unplanned failures. Its internal mounting system and flexible drive options (pneumatic or electric) allow for fast setup and machining without removing the flange from the system, greatly minimizing operational disruptions.
