A Companion Flange, sometimes referred to as a hub, is a flange that corresponds to another flange. It has bolt holes that align with another flange is a trait of this type of flange. Usually a companion flange features a Raised Face (RF) or Ring Joint (RTJ), with a threaded outlet. Also called a Threaded Flange by some people.
The companion flange is an important component of a pipeline, a plumbing system or wellhead christmas tree. In most situations, this flange is attached to the flange of another pipe and then the pipeline is assembled to fit tightly between the two flanges. A threaded companion flange is also used on a plastic pipe when adding a threaded iron pipe into the pipeline. Companion flanges can be used in the field or in a shop environment for various testing applications.
