FI40 6''–40" Industrial ID-Mounted Flange Facing Machine: Portable Precision In-Situ Refacing

The FI40 is a heavy-duty, internal-diameter (ID) mounted flange facing system engineered to restore workshop-grade surface geometry directly on-site. Designed for critical plant turnarounds, this portable unit covers a broad machining range from 6" to 40" (153–1000 mm).

By re-machining corroded, scored, or warped sealing faces back to strict ASME B16.5 standards, the FI40 eliminates the costly need to cut, torch, and re-weld large-diameter piping. This on-site approach minimizes facility downtime while ensuring leak-free gasket sealing across high-pressure systems.

Frequently Asked Questions (FAQ) – FI40 Flange Facer

Q1: What is the maximum and minimum flange diameter the FI40 can machine?

A: The FI40 Flange Facer can machine flanges from 6 inches (153 mm) to 40 inches (1000 mm) in diameter, making it ideal for a wide range of industrial applications.

Q2: Is the machine suitable for both flat face (FF) and raised face (RF) flanges?

A: Yes, the FI40 is capable of machining flat face (FF), raised face (RF), ring type joint (RTJ), and other groove profiles such as V grooves and weld repairs, all in compliance with ASME standards.

Q3: What are the differences between the pneumatic and electric models?

A: FI40P (Pneumatic) uses a Modec air motor, suitable for explosive environments or sites without power supply.

FI40E (Electric) features a servo motor, offering precise speed control and ease of use in well-powered settings.

Q4: Can the FI40 be used in vertical or overhead positions?

A: Yes, thanks to its internally mounted design and modular structure, the FI40 can operate in any orientation, including vertical and overhead setups.

Q5: How long does it take to set up the machine on-site?

A: With its quick-set independent mounting bases and micro-adjustable jaws, setup typically takes 15–30 minutes, depending on the flange condition and operator experience.
