Bleed Ring - ANSI Class 150-2500 (in)

Written by Matt Milbury. Posted in Accessory Datasheets

A bleed ring is a machined piece of metal 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 bleed ring can also be made to matched with any flange type.  The dimensions on this page are for bleed rings that have a machined face for use with raised face flanges.
