This reducer consists of the symmetrical and conical shaped fittings that enlarge or reduce the diameter equally about the center line. For an example, when 1” pipe transitions to ¾” pipe, then the top or bottom of the pipe do not remain level.
Concentric Reducers are used to join pipe or tube sections on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. A pipe reducer can be a single diameter change or a multiple diameter change. The pipes cannot recognize what the outside configuration of the pipe reducer looks like.
Concentric reducers are designed with the small and large diameters on opposite ends and joined by a cone shaped transition section. They are available in both seamless and welded construction.
The pipe flow is affected by the inside diameter conical transition configuration which can be axially moved and externally reconfigured to provide for more economical reducer fittings. Thus, concentric reducers connect pipes of unequal size but have a common centerline. In other words, it is a type of pipe fitting with different size ends to join pipes of different diameter that joins pipe sections on the same axis.
Butt weld reducer can adjust the flow rate and speed. One end welded with a large diameter pipe and another end with a smaller OD pipe. It has two types:
Concentric and Eccentric Reducer.
Use these concentric reducers to connect two carbon steel pipes with different inside diameters. The carbon steel construction is stronger than stainless steel, is very resistant to wear, and can withstand high pressure, but is also susceptible to corrosion.
