A Drip 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 Drip Ring has different sizes based on the ANSI flange rating of the process piping.
