Flange facing services by ABS Group

 

What is Flange Facing?

Flange facing is an onsite machining service conducted on a flange to avoid leakages and corrosion. This service helps maintain the joint integrity required between two flange surfaces.

Why is Flange Facing Required?

Flanges constantly experience damage from corrosion or erosion due to turbulent flow, impacts with other components during construction or installation or cuts from gasket leaks.

 

What is the Difference Between Internal Diameter (ID) and Outside Diameter (OD) Mounting?

Flange facing machines can be mounted in two ways. In ID mounting, the machine is placed inside the flange with clamp legs inside. Externally mounted machines are placed around the flange with the clamp legs pushing inwards.
