ASTM A182 F55 Forged Pipe Fitting S32760 Duplex Steel Bleed Ring / Drip Ring / Vent Ring

A bleed ring, also known as a drip ring or vent ring, is a specialized fitting used in piping systems, particularly in the oil and gas industry. A bleed ring is a circular device installed between two flanges in a piping system. They can have threaded or socket-weld connections and are designed to fit within the bolt circle of standard flanges It typically features one or more radial or tangential ports. These ports can be fitted with plugs or valves to control the flow of fluid or gas. 

Bleed rings are commonly made from durable materials such as carbon steel, stainless steel, and various alloys. These materials ensure they can withstand harsh operating conditions.

Primary Functions:

• Pressure Relief: Bleed rings help prevent overpressurization by allowing excess pressure or fluid to be safely released.
• Drainage and Sampling: They provide a convenient point for draining fluids or taking samples without interrupting the flow.
• Leak Detection: By monitoring pressure changes through the bleed ring, operators can detect leaks

Material & Grades of Bleed Rings

Benefits of using bleed ring

• Safety: By providing a controlled method for pressure relief, bleed rings help prevent equipment failure and ensure worker safety.
• Efficiency: They allow for targeted maintenance and sampling without shutting down the entire system.
• Customization: Bleed rings can be customized in terms of material, size, and connection types to suit specific applications

Applications

• Oil and Gas Industry: Bleed rings are extensively used in refineries, petrochemical plants, and offshore platforms. They are crucial for pressure relief systems and flow measurement applications.
• Maintenance and Inspection: They simplify flange maintenance by allowing operators to release residual fluid or gas.
• Sampling and Testing: In custody transfer processes, bleed rings enable periodic sampling to ensure fluid quality
