FE12 Flange Facing Machine | OD-Mounted Tool for Pipe End and Flange Repair

The FE12 Flange Facing Machine is a heavy-duty, OD-mounted solution engineered for precision resurfacing of damaged or corroded flange sealing surfaces up to 12 inches (305 mm) in diameter. Designed for both field and workshop use, this versatile flange facing machine delivers flatness restoration and ASME-compliant spiral serrated finishes, ensuring leak-free flange connections in high-pressure systems.

Its externally mounted (OD-mount) configuration eliminates the need for internal pipe access, making it ideal for applications where internal entry is restricted or hazardous. Suitable for vertical, horizontal, and overhead setups, the FE12 is widely used in the oil and gas industry, petrochemical plants, power generation facilities, and offshore platforms, where reliable flange repair and maintenance are critical to operational integrity. Whether performing routine maintenance or emergency repair, the FE12 provides consistent results, portability, and operator-friendly features that make it a trusted choice for professional machinists.

INDUSTRIES AND APPLICATIONS

The FE12 flange facing machine is widely used in industries where precision sealing surfaces are critical to safety, performance, and compliance. Its externally mounted design and ability to generate ASME B16.5-compliant spiral serrated finishes make it the ideal solution for a wide range of flange resurfacing and maintenance tasks in the following sectors:

Oil and Gas Industry

Used extensively for the maintenance of flanged connections in refineries, pipelines, and offshore drilling platforms. The FE12 enables technicians to restore damaged or corroded flange faces on oil lines, gas separators, and pressure vessels—eliminating leaks and preventing costly downtime.

Petrochemical and Chemical Processing

In chemical processing environments, the integrity of flanged joints is crucial for safety and environmental compliance. The FE12 ensures that all flange sealing surfaces meet tight flatness and finish tolerances after shutdowns or gasket failures, reducing the risk of hazardous leaks.

Power Generation Facilities

Applicable to thermal, nuclear, and renewable power plants, this machine efficiently resurfaces high-pressure steam and fluid system flanges. Its precision feed rates and portability make it ideal for use in limited-access turbine halls, boiler rooms, and pipe racks during outages.

Maintenance, Fabrication and Industrial Workshops

The FE12 supports workshop and field teams with consistent, repeatable flange finishing for repair and retrofit projects. Its rugged design and quick setup optimize workflow in environments where power sources and space are limited.
