Bleed Rings

In this paragraph I am going to tell you about bleed rings & drip rings. Firstly they have many names. For example, bleed rings & drip rings are also known as a bleeder ring, flushing ring, vent ring or a test insert. Furthermore, a bleed ring is in a shape of a ring designed to fit between pipe. Along with standard flanges, using most material. The bleed ring (Drip ring, bleeder ring, flushing ring, vent ring, Test Insert) can come in any material or size, and is designed for connecting valves and instruments. The face of the Drip ring can be manufactured to match with any flange type. The standard sizes for a bleed ring are 1″ to 24″ and, ANSI ratings from 150# through 1500#.

Drip Rings

Dannenbaum LLC can supply any size or material for the bleed rings. Standard material is carbon steel. Bleed Rings can provide a beneficial way of draining piping, taking samples, attaching instruments or even bleeding of a valve. They can also be used with a valve and/or blind flange. Therefore, this allows you to reduce and dispose of the pressure for your valve before you remove the flange. This is usually done with a replacement for a leaky valve. Contact Dannenbaum LLC for more information.

Vent Rings

A bleed ring is a section 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. A drip ring has different sizes based on the ANSI flange rating of the process piping.

A bleed ring can be used instead of an orifice flange union. It is easier to install and cheaper than installing orifice flanges, especially in a brown field application. It comes in many different materials such as carbon steel, stainless steel, PVC, ect., depending on the use. They provide a convenient way of draining piping, taking samples, attaching instruments or even bleeding of a valve. When used with a valve and blind flange, it allows you to relieve the pressure if your valve is leaking before you remove the flange.
