What is Flange?
Performing machining maintenance on flange surfaces is known as flange facing. So these flanges are well maintained and repaired on regular basis to protect from leaks and corrosion. Treatments like these guarantee joint integrity in aged flanges.
Benefits
Why Do We Need Flange?
During construction, installation, or cuts caused by gasket leakage leads to flange damage while turbulent flow and interactions with other components. A spiral grooved finish is achieved by facing flanges. This finish makes flanges less prone to leaks as gases and liquids are forced to move in a lengthy spiral route rather than over the flange face. During factory shutoffs or maintenance, flange facing is regarded as one of the most significant repair operations.
Versatility is Important?
You can choose from ten different types of jacks to serve flanges ranging in diameter from 775 to 3061 millimeters. It is possible to create angled cuts such as o-rung grooves, chamfers, square shoulders, etc. by spinning the tool head and tool bit separately 360 degrees. Completely rotating the tool bit also provides for appropriate tool bit location.
For situations with bridge obstacles or where service is necessary on the rear of the pipe flange or exchanger, the choice of a back-facing attachment allows additional freedom in machining operations. The replaceable feed trippers on this model further enhance its adaptability, enabling numerous mounting configurations.
Flange Facing is Needed in Which Industries?
Flange facing is more commonly required in the oil and gas, petrochemical, pharmaceutical, and electrical industries than in other segments.
Power Options: What Are They?
Compressed air is the primary means of propelling most flange facing tools in the oil and gas sectors due to the importance of flanges. In addition to electrical and hydraulic tools, others are also available for other industries.
Applications of Flange Facing
- Main intake steam flanges were refaced.
- Pipe facing and beveling are essential for sealing and weld prep.
- Flanges with flat faces, raised faces, and phonographic finishes can be repaired.
- Repair the flanges that connect the piston rods.
- Feed pumps for boilers.
- Tube sheets need to be re-machined to eliminate seams.
- New ring grooves need to be made or existing grooves need to be fixed.
- Preparation of the vessel and plate welds.
- Resurface the sealing surfaces on ship hatches.
- Repair of a rotary crane’s bearing surfaces.
- Large pump base housings are being resurfaced.
- Heating exchangers can be repaired and valve flanges can be resurfaced.
- Wind turbine flange milling section.
- Faceting, drilling, and machining of ship thruster mounts.
