The Steam Rotary Joint acts as a bridge between the fixed steam pipe and the rotating heating part, and although it is small, it is a vital task. In many industrial processes, a steady input of heat is key to ensuring product quality and process efficiency. For example, in the fields of papermaking, food processing, textile printing and dyeing, plastic molding, etc., equipment often needs to be continuously heated by rotating rollers or shafts.

The rotary joint for steam is also called a high temperature rotary joint. Commonly known as plum-type rotary joints. It is a typical Q-type rotary joint.
