A bleed ring is a ring 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. The face of the ring can also be made to matched with any flange type. A bleed 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.
Bangdong manufactures a wide variety of Carbon and Stainless Steel Bleed Rings .
They are typically furnished with a 0.5'' or 0.75'' Socket Weld or Threaded Side Tap. Customer specific tapping is available upon request.
Stock material grades include A516 Gr70 and A240 Stainless Steel. Alloys upon request.
