What is bleed ring?
Able to be matched with any flange type, bleed rings are a ring section with one or more radial pipe connections designed to fit between standard flanges with the bolt circle, using conventional gasket materials.
Standard bleed rings are manufactured with at least one 1/2-inch or 3/4-inch tapping to allow easy connection of valves and instruments. While Bleed rings with multiple taps or alternative tap sizes are available, these may impact the overall thickness of the ring. Bleed rings are available in a variety of materials such as stainless steel, carbon steel and special alloys as required.
Bleed Ring Usage:
Bleed Ring Standards and Regulations
For more information on bleed ring standards, consult the following ASME standards:
ASME B16.5 - Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard
ASME B16.20 - Metallic Gaskets for Pipe Flanges: Ring-Joint, Spiral-Wound, and Jacketed
ASME B16.47 - Large Diameter Steel Flanges: NPS 26 Through NPS 60 Metric/Inch Standard
ASME B16.48 - Line Blanks
It’s also important to consider that despite being comparable to very thick, solid metal gaskets, bleed rings may require registration as a fitting and a CRN depending on your intended usage and use environment.
