INDUSTRIES AND APPLICATIONS

The FI40 Flange Facing Machine is engineered for precision flange resurfacing in the most demanding industrial environments. Designed for on-site machining of large-diameter flanges, it offers unmatched performance across a broad spectrum of sectors. Its internally mounted configuration, high machining capacity (6"–40"), and portable design make it ideal for both scheduled maintenance and emergency flange repair.

Oil and Gas Industry

The FI40 is widely deployed for flange facing operations during turnarounds, pipeline maintenance, and refinery overhauls. It handles flanges on oil transmission lines, gas processing units, separators, heat exchangers, and other critical pressurized systems — ensuring flange surfaces are restored to ASME B16.5 compliance for leak-free sealing.

Power Generation

From fossil fuel plants to nuclear facilities and renewable energy stations, the FI40 performs accurate flange resurfacing on high-pressure steam lines, turbine housings, condenser connections, and heat recovery systems. Its precision feeds and rigid mounting base help reduce downtime during scheduled outages.

Chemical and Petrochemical Plants

Corrosive environments in chemical plants often degrade flange surfaces. The FI40 provides on-site precision machining for flanges in reactors, distillation columns, process piping, and pressure vessels — supporting safe and efficient recommissioning.

Shipbuilding and Marine Maintenance

Ideal for shipyards and offshore platforms, the FI40 flange facer is compact enough for confined engine rooms and robust enough for on-deck operations. It restores damaged flange faces on pipelines, valves, and seawater systems, essential for Class approval inspections and vessel integrity.

Industrial Equipment Manufacturing

In heavy equipment fabrication, where large flanges are used on pumps, compressors, and hydraulic systems, the FI40 is used for surface preparation, weld seam finishing, and machining sealing grooves before final assembly — ensuring proper alignment and sealing.

Offshore and Subsea Applications

Corrosion and mechanical wear are common in offshore installations. The FI40 is optimized for modular disassembly and transport, enabling technicians to carry out flange repairs on FPSOs, platforms, and subsea equipment with minimal disruption.
