Flange Facing

Flange facing is a machining process in which the faces of flanged and other types of pipe and vessel connectors are machined. Faces can be damaged due to impacts with other components at the time of construction or installation and due to corrosion or erosion caused by gasket leaks. Hub profiles, the front and rear face of heat exchangers, oval man ways, oval handholds and sealing surfaces of pressure vessels and boilers are machined by the flange facing process.

Machinable flanges are:

Vee Groove
RTJ Groove
Blind
Pipework flanges
FPSO turret flanges
Crane seats
Square, Oval and Irregular shaped manway doors
Lens Ring Groove
Full Faced & Raised Face
Thruster housing faces
Tube Sheet Face and Back Face
Cylinder liner entablature faces
Diving/compression chamber flanges
Stern tube faces rudder housing faces

Flanges and connectors can be re-machined to original specifications conforming to relevant standards such as – IS , BS, ANSI
