Ring Joint Facings - ASME/ANSI B16.5 & B16.47

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.

Pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification.

Note:

- Values for minimum flange thickness,

C, and overall length, D, are detailed in

the flange tables.

- For ring joint tolerances see page 8-9.
