Bleed rings provide a convenient way of draining piping, taking samples, attaching instruments or even bleeding of a valve. Unified Alloys stock bleed rings in stainless steel and other corrosion resistant material options.

A bleed ring is machined from forged metal with one or more radial pipe connections designed to fit between standard flanges within the bolt circle, using conventional gasket material. The ring normally comes with a 3/4" tapped or 1/2" socket weld for connecting with valves and instruments.

The typical bleed rings have a machined face (125-250 RMS) for use with raised face flanges.

Please note: 1" NPS tappings and above will require a thicker bleed ring to accommodate the additional outside diameter of the tapping.
