Product Introduction
Powered by compressed air, outside Diameter Flange Facer is suitable for applications where electrical sparks need to be avoided. It can machine flange faces, sealing surfaces and related grooves, including RF and RTJ-type surfaces, depending on the tooling configuration. Its portable design allows damaged or worn flanges to be repaired on site without removing the entire pipeline or transporting large components to a workshop.
Product Advantages & Features
1. External Clamping Design
The external clamping system provides stable mechanical support during flange machining and is suitable for large-diameter flange applications.
2. Pneumatic Drive
The compressed-air drive provides fast start and stop response and eliminates the need for an electric drive at the machine. It is particularly useful in applications where electrical sparks should be minimized.
3. Portable On-Site Machining
The portable design allows operators to repair flange sealing surfaces directly at the job site, reducing the need to remove and transport large flanges.
4. High Rigidity
The external clamping structure provides strong support for machining operations and helps maintain stable cutting performance.
5. Adjustable Feed Control
The feed handwheel with a scale display allows operators to control tool movement more accurately during flange face machining.
6. Wide Machining Range
Wellnit offers external clamp pneumatic flange processing machines covering different flange sizes. Current models listed by Wellnit include machining ranges from approximately 0–300 mm to 0–3000 mm O.D., depending on the model

Tool Post Feed Handwheel
The core function of the tool holder feed handwheel is to allow the operator to directly and accurately control the position of the cutting tool radially (toward or away from the center).
Tool holder symbol explanation and feed direction settings
N means neutral, rotates without load "IN" means forward gear, indicating feed from inside to outside. "OUT" means reverse gear, indicating feed from outside to inside. ["3" "2" "1"] Adjust feed rate
Horizontal feed handwheel
Switch the gear lever, and gently turn the [horizontal feed handwheel] when engaging the gear. Make sure the gear is fully engaged.
No directional restrictions
It can be installed horizontally, vertically, or upside down, with no restrictions on working position, making it suitable for any work environment.
Materials

The portable design makes the machine suitable for flange repair and maintenance in shipyards, marine equipment and other restricted working areas.
Machinery Maintenance
Used to restore worn, scratched or uneven flange sealing surfaces without sending large components back to a machining workshop.
FAQ
Q: What is a pneumatic external clamp flange facing machine?
A: It is a portable machining machine that uses an external clamping system and compressed-air drive to machine or repair flange sealing surfaces. It is designed for on-site flange facing and resurfacing.
Q: What is a flange facing machine used for?
A: A flange facing machine is used to repair and machine flange sealing surfaces, helping restore the required surface condition for proper gasket sealing. It can also be configured for machining sealing grooves and other flange features.
Q: What is the difference between external clamp and internal expansion flange facers?
A: An external clamp flange facer is mounted on the outside diameter of the flange, while an internal expansion flange facer is mounted inside the flange bore. External clamping can be a practical choice for larger flanges or applications where internal access is limited.
Q: Can it machine RF and RTJ flanges?
A: Yes. The machine can be used for flange face and sealing surface machining, including RF and RTJ-related applications, depending on the tooling and machining configuration.
Q: Can the flange be repaired without removing the pipeline?
A: Yes. One of the main advantages of a portable flange facing machine is on-site machining. In suitable working conditions, the flange can be repaired directly on the installed pipeline, reducing disassembly and transportation work.
Q: Does Wellnit support customization?
A: Yes. Wellnit provides OEM and customized solutions according to customer requirements. Customers can provide flange dimensions, drawings, machining requirements and application conditions for technical evaluation.
