One end of an eccentric reducer pipe is flat; as the diameter changes, both the position and direction of the cutting point vary. Accordingly, the installation and functionality of an eccentric reducer pipe also differ. Specifically: when the cutting point at the pipe opening faces upward, this configuration is referred to as a top-mounted installation, typically used at pump inlets and conducive to air venting.
One end of an eccentric reducer is flat; as the diameter changes, the position and orientation of the cutting point also vary. Accordingly, the installation and functionality of an eccentric reducer differ depending on its configuration. Specifically: when the cutting point at the pipe opening faces upward, this arrangement is referred to as a top-mounted installation, typically used at pump inlets and conducive to air venting.

When the pipe opening’s tangent point becomes the bottom-mounted device, it is typically used for regulating valves and drainage systems. In general, horizontal liquid pipelines usually employ eccentric reducers. The manufacturing method and process for reducing-diameter pipes should be selected based on user requirements and national standards. Generally speaking.
The roundness of pipes with different diameters should not exceed 1 percent of the corresponding outer diameter at either end, with an allowable deviation of up to ±3 mm. The forming processes for tapered pipes include reduced-diameter forming, expanded-diameter pressing, or a combination of reduced-diameter and expanded-diameter forming. Stamping can also be used for certain specifications of pipe materials with varying diameters.
Regardless of which forming method is chosen, the manufacturing process for variable-diameter pipes is similar: it always involves inspecting the incoming material, marking the workpiece, verifying the cut material, checking the fitting and folding processes, and only then proceeding to actual forming. The above article provides an introduction to eccentric pipes; we hope it has given you some insight.
