how to test eccentric reducer dimensions
Eccentric reducer is a kind of pipe fittings used for reducing the diameter of pipes. The forming process usually used is reduced diameter pressing, expanded diameter pressing or reduced diameter plus expanded diameter pressing. For some specifications of reduced diameter tubes, stamping can also be used.

In addition to the use of steel pipes as raw materials for eccentric reducers, some specifications of reducers can also be produced by stamping with steel plates. The shape of the die used for drawing is designed with reference to the inner surface size of the reducer. After blanking, the steel sheet is pressed and stretched.

Both ends of the concentric reducing pipe have the center of the circle on the same axis. When changing the diameter, the position of the pipe will not change when calculating the pipe position based on the axis. It is generally used for gas or vertical liquid pipe diameter reduction. The ends of the eccentric reducer are cut in the circumference of the mouth and are generally used for horizontal liquid pipes.

How to test the size of the reducer:
First select the size of the two ends of the reducer according to the size of the two different pipes to be linked, and select the concentric reducer or eccentric reducer according to the purpose.

Select the wall thickness specifications of the reducer according to the wall thickness of the pipe.
When the tangential point of the eccentric reducer pipe is upward, it is called top-level installation. It is generally used for pump inlet to facilitate exhaust. Concentric reducers are conducive to fluid flow. When changing the diameter, the interference to the fluid flow state is small. Therefore, concentric reducers are used for gas and vertical flowing liquid pipelines. The eccentric reducer is flat on one side, which is good for exhausting or draining liquid, which is convenient for startup and maintenance. Therefore, eccentric reducer is generally used for horizontally installed liquid pipes.
