Reducer is a type of pipe fitting used for connecting pipes of different diameters. According to their different shapes, they are divided into two types: concentric reducer and eccentric reducer. Concentricity is easy to understand as the center points of the circles at both ends of the pipe being on the same straight line, which is called a concentric reducer. Conversely, it is called an eccentric reducer. The large and small heads are suitable for controlling water, gas, oil products, and corrosive media in industries such as chemical, petroleum, metallurgy, light industry, electricity, plumbing, food, medicine, fiber, ink, etc.

The key function of a pipe reducer is to facilitate a smooth transition between pipes of different sizes while maintaining the flow capacity of the piping system. It helps to avoid turbulence, pressure drops, and excessive resistance to flow. Pipe reducers are commonly used in various industries, including oil and gas, chemical processing, water treatment, and HVAC systems.
