The Difference of Concentric Reducer and Eccentric Reducer

Jul. 07, 2020

I believe that many people know what steel pipe fittings are, but they don’t know what a reducer is. It is also divided into concentric non-reducing pipes and eccentric reducers. You may not know how to use these two kinds of fittings. The following BSP Fittings supplier takes you to understand the application of concentric reducer and eccentric reducer. Before we understand the application, first understand what the reducer is!

Reducing pipe is one of the chemical pipe fittings, used to connect two different pipe diameters. The materials of the reducer include stainless steel reducer, alloy steel, carbon pipe head of reducer, and reducer 20 steel. Reducing pipe is a pipe fitting used to change the pipe diameter. The commonly used forming process is reduced-diameter forming, enlarged-diameter forming or reduced-diameter plus expanded-diameter forming, and stamping forming can also be used for certain specifications of pipes of different diameters. The shrinkage hole forming process of tubes of different diameters is to put the tube blank and the tube with the same diameter at the large end of the tubes of different diameters into the forming die, and squeeze along the axial direction of the tube blank to move and shrink the metal along the mold cavity. According to the variable diameter of different pipe diameters, it can be divided into one press forming and multiple press forming.

Concentric Reducer

Concentric Reducer

What are eccentric reducers and concentric reducers?

Reducing pipes are also called big and small heads and are used to connect pipes of different sizes. Eccentric reducer refers to tubes with different diameters whose centers are not on the same straight line. Tubes with a center on the same line are called concentric reducers. The commonly used forming process is reduced-diameter forming, enlarged-diameter forming or reduced-diameter plus expanded-diameter forming, and stamping forming can also be used for certain specifications of pipes of different diameters.

Application of eccentric reducer

The diameters of the two ends of the eccentric reducer are different, so they are used to connect pipes or flanges with different diameters to change the diameter. The eccentric pipes of different diameters at both ends of the mouth have the center of the circle on the same axis. When the shaft diameter is used to calculate the pipe diameter, the position of the pipe remains unchanged. It is generally used for the change of the diameter of gas or vertical liquid pipes.

The eccentric pipe ends of different diameters are cut eccentrically in the circumferential direction and are generally used for horizontal liquid pipes. When the cutting point of the eccentric pipes of different diameters is upward, it is called top installation. It is generally used for the pump inlet and is conducive to exhaust. The cutting point is inserted into the bottom to install. It is generally used for the installation and drainage of control valves.

The eccentric reducer pipe is conducive to fluid flow, and changing the diameter has less interference with the fluid flow pattern. Therefore, concentric and eccentric reducer pipes are used in liquid pipes containing gas and vertical flow.

Eccentric reducer pipe fitting is a kind of pipe fitting suitable for different pipe diameters. The commonly used forming process is reducing diameter, expanding diameter or reducing the diameter, and expanding pressure. Stamping forming can also be applied to certain specifications of pipes with different diameters.

Application of Concentric Reducer

Concentric reducers will not produce corrosion, pitting corrosion, corrosion or wear, and can play a good role and performance in the industry. Concentric circular tubes are also one of the high-strength materials in construction metal materials.

The above is the specific content of concentric reducer and eccentric reducer shared for you, I hope to help you.
