A stainless steel concentric reducer is a type of pipe fitting that is used to connect pipes of different sizes in a piping system. It is a conical shaped fitting that narrows down the diameter of a pipe while maintaining the centerline of the pipe. The reducer has a large end and a smaller end, and it is used to join pipes of different sizes by welding or threading. Stainless steel concentric reducers are commonly used in industrial piping systems where it is necessary to reduce the flow of fluid or gas. They are made of high-quality stainless steel, which makes them resistant to corrosion and suitable for use in high-pressure and high-temperature applications. The concentric design of the reducer ensures that there is no turbulence in the fluid flow, which helps to maintain the overall efficiency of the piping system.
