Backing Ring Flanges, Backing Flanges, and Backup Flanges are all different terms used to describe the same type of flange. These flanges are used to reinforce and support flanged connections in piping systems.
A backing ring flange is a ring-shaped component that is installed between two flanges in a pipeline. It is typically made of a material that is compatible with the pipe and flange materials, such as carbon steel, stainless steel, or PVC. The purpose of a backing ring flange is to provide additional support to the joint and prevent the flange from deforming or breaking under high pressure or temperature.
The terms “backing flange” and “backup flange” are also commonly used to refer to this type of flange, although they may be used in slightly different contexts. For example, a backing flange may be used to describe a flange that is installed on the backside of a piping component, while a backup flange may be used to describe a flange that is used as a backup or replacement for a damaged flange.
Regardless of the terminology used, these types of flanges are an important component in many piping systems and are used in a variety of industries, including oil and gas, chemical processing, and water treatment.
