Carbon Steel Flange Forged Bleed Ring Drip Ring Flush Ring A105

A bleed ring, also known as a drip ring or bleed flange, is a specialized component commonly used in piping systems to allow for the safe venting, draining, or sampling of process fluids. It is typically installed between flanges in a pipeline and has a small tapped hole to provide access to the contents of the pipe.Bleed rings also known as Drip rings are placed inside the circular bolts between flanges, mainly to drain or bleed of excess liquid via a valve, thus minimizing the effects of corrosion in steel pipes.Bleed rings can be supplied with threaded or socket-weld taps and for raised-faced or ring-type joint (RTJ) configuration, both male and female. All rings are made in accordance with B16.48.

Features of a Bleed Ring:

1. Shape: It is usually circular with a radial hole (tap) for attaching valves, gauges, or other instrumentation.
2. Material: Common materials include stainless steel, carbon steel, and other alloys suitable for the operating conditions of the system 
3. Design: The bleed ring fits between two flanges and contains bolt holes that align with the flange bolts, ensuring a secure and leak-proof installation.

Common Uses:

1. Venting: Allows for the safe release of trapped gas or air in the system.
2. Draining: Used to drain liquid from the pipeline without disassembling the system.
3. Sampling: Provides access to take fluid samples for testing.
4. Instrument Connections: Can be used as a connection point for pressure gauges, relief valves, or other instruments.

Benefits:

• Easy to install and remove.
• Avoids the need for more invasive modifications to the pipeline.
• Increases system safety by facilitating controlled fluid handling.

Typical Applications:

• Oil and gas pipelines.
• Chemical and petrochemical plants.
• Power generation facilities.
• Water and wastewater treatment systems.
